4th Canadian Division

The 4th Canadian Division is a formation of the Canadian Army headquartered in , , tasked with generating and sustaining combat-ready, multi-purpose land forces at specified readiness levels to support defence priorities, with a primary focus on operations within . Comprising over 13,000 personnel—including , reserve force, , and civilians—it oversees units across 46 communities in the province, drawing on major bases such as and Kingston. The division emphasizes training, readiness for domestic emergencies, and contributions to international missions, maintaining a structure that integrates , , engineers, and support elements under the command of a brigadier-general. Formations designated as the 4th Canadian Division have appeared multiple times in Canadian history, though the current iteration stems from post-1991 reorganizations rather than direct perpetuation of wartime units. During the First World War, the original 4th Canadian Division was raised in in April 1916 from elements, deploying to France that August to join the on the Western Front, where it engaged in sustained , assaults at Vimy Ridge, and advances through and the until in 1919. In the Second World War, a new 4th Canadian Division was authorized in as but redesignated the 4th Canadian Armoured Division in 1941 after conversion to armoured units; it trained in the before landing in in July 1944 as part of II Canadian Corps, participating in the closing of the Falaise Gap, the , and subsequent drives liberating Belgian and Dutch territory en route to by war's end. These historical divisions contributed to Canada's through high-casualty engagements that prioritized empirical tactical adaptations, such as manoeuvres, over doctrinal rigidity.

Origins and World War I Service

Formation and Early Deployment

The 4th Canadian Division was authorized for formation in late 1915 but officially established on 25 April 1916 in England, drawing from existing Canadian units stationed there and reinforcements scheduled to arrive from Canada. Organized primarily at Bramshott Camp under the command of Major-General David Watson, the division comprised the 10th, 11th, and 12th Infantry Brigades, along with supporting artillery, engineers, and machine-gun units, totaling approximately 15,000 to 18,000 personnel by mid-1916. Watson, a Canadian officer with prior experience commanding the 4th Infantry Brigade, prioritized rapid assembly to bolster the Canadian Corps amid ongoing demands on the Western Front. Initial training emphasized , rifle drill with the Lee-Enfield, gas defense, and coordination with , conducted at Bramshott through July 1916 before the division embarked for in early August. The units crossed the and began disembarking in by mid-August, with the division entering the line for familiarization on 25 August 1916 in a relatively quiet sector to acclimate troops to trench conditions. Further training followed at St. Omer in September, including practice with creeping barrages and raid simulations, as the division prepared for integration into the Canadian Corps, which it formally joined by late November. Early deployment shifted to the offensive in , where the 4th Division relieved exhausted units of the 1st and 3rd Canadian Divisions by 10 October, taking over positions amid mud, rain, and entrenched German defenses. The division's first major actions centered on Regina Trench, a fortified German position dominating the battlefield; assaults by the 11th Brigade on 1 and 8 failed with heavy casualties due to inadequate artillery support and wire entanglements. Partial success came on 21 when the 87th and 102nd s captured a 600-yard section, securing 160 prisoners, though subsequent attacks on 25 by the 44th stalled amid poor barrage coordination, incurring around 200 casualties. Persistence paid off on 10-11 November, as the 10th and 11th Brigades fully seized Regina and adjacent Desire Trenches, capturing 90 prisoners despite fierce resistance and appalling weather that turned the ground into a quagmire. A final push on 18 November advanced half a mile, netting 625 prisoners at a cost of 1,250 casualties, marking the division's in the protracted fighting.

Major Engagements on the Western Front

The 4th Canadian Division arrived in in mid-August 1916 and entered the line near Ypres-Comines Canal on 25 August, relieving elements of the amid ongoing Somme operations. Its initial major engagement came during the later phases of the , particularly around Regina Trench from 21 October to 11 1916, where the 11th Brigade captured a 600-yard section on 21 October, taking 160 prisoners at a cost of 200 casualties, while the 44th Battalion's assault on 25 October failed with approximately 200 losses. By 10-11 , the division secured the remainder of Regina and Desire Trenches, capturing 90 prisoners with lighter casualties, and on 18 advanced about 0.5 miles over a 2,200-yard front, yielding 17 officers and 608 other ranks as prisoners but incurring 1,250 casualties overall. In April 1917, the division participated in the (9-14 April), assaulting Hill 145 on 9-10 April with battalions including the 72nd, 73rd, 75th, and 54th, capturing it along with 150 prisoners, followed by the seizure of The Pimple on 12 April for 500 prisoners. Preparatory actions in late February to early March involved 1,700 troops and resulted in 687 casualties from failed surprises and gas exposure, contributing to the Canadian Corps' overall capture of the ridge despite total casualties of 10,602 (3,598 fatal). Later in 1917, during operations around , the division captured (26-29 June) and took part in the (15-25 August), repelling multiple German counter-attacks alongside the 1st and 2nd Divisions to secure strategic heights, though with Canadian casualties totaling 9,198 for the operation. The division's role in the Third Battle of Ypres intensified at from 26 October to 10 November 1917, where the 44th and 85th Battalions captured Bellevue Spur (26-28 October) at a cost of 2,481 casualties (585 killed, 965 wounded), and the 12th Brigade (85th, 78th, 72nd Battalions) assaulted on 30 October to take Crest Farm and positions east of the Passchendaele road, suffering 884 killed and 1,429 wounded amid mud and resistance. These actions supported the 3rd Division's push, securing higher ground and the village by 6 November, though conditions limited broader advances. During the Hundred Days Offensive in 1918, the 4th Division advanced at Amiens (8-11 August), covering 6,000 yards on a 7,000-yard front and capturing key positions. It then breached the Drocourt-Quéant Line (2-3 September) and assaulted the Canal du Nord (27 September-1 October), defeating 50 German battalions, capturing Bourlon Wood, and taking approximately 3,000 prisoners en route to Cambrai. Final engagements included Valenciennes (1-2 November), seizing Mont Houy and the town by 3 November with significant prisoner hauls, and the passage of the Grande Honelle (5-7 November), contributing to the armistice on 11 November.

Organizational Structure and Infantry Units

The 4th Canadian Division, formed on 26 April 1916 in under Major-General David Watson, was structured as a standard of Expeditionary Force, comprising three brigades each with four battalions, , engineers, machine-gun companies, and other supporting elements. Initially lacking dedicated divisional , which was added in June 1917 from existing Canadian units in France, the division's formed its core combat strength, totaling approximately 12,000 rifles by late 1916. Each brigade included trench mortar batteries equipped with Stokes mortars and machine-gun companies that were consolidated into the 4th Battalion, Canadian Machine Gun Corps, by March 1918, providing 96 guns across four companies. The 10th Canadian Infantry Brigade, commanded initially by Brigadier-General W. St. P. Hughes, consisted of the 44th Battalion (), 46th Battalion (South Saskatchewan), 47th Battalion (British Columbia), and 50th Battalion (Calgary). These units, drawn from western Canadian recruits, maintained their four-battalion composition throughout the war without major disbandments. The 11th Canadian Infantry Brigade, under Brigadier-General Victor W. Odlum, included the 54th Battalion (Kootenay), 75th Battalion (Mississauga), 87th Battalion (Canadian Grenadier Guards, joined June 1916 from the 12th Brigade), and 102nd Battalion (North British Columbia). This brigade's battalions reflected a mix of British Columbia and eastern Canadian personnel, with the 87th providing Montreal-based guardsmen. The 12th Canadian Infantry Brigade, led initially by Lord Brooke and later Brigadier-General J. H. MacBrien, underwent more changes: it started with the 38th Battalion (Ottawa), 51st Battalion (Edmonton, detached November 1916), 72nd Battalion (), 73rd Battalion (, disbanded April 1917 due to manpower shortages), and 78th Battalion (Winnipeg Grenadiers), later reinforced by the 85th Battalion () from April 1917. By mid-1917, it stabilized at four battalions, emphasizing highland and central Canadian units. Supporting the infantry was the 4th Canadian Pioneer , redesignated from the 67th in September 1916 but disbanded in April 1917, with personnel redistributed to other units like the 54th and 102nd . strengths were often augmented beyond establishment by 100 men each to offset casualties, ensuring the division's resilience in prolonged .

World War II as 4th Canadian Armoured Division

Mobilization and Training

The 4th Canadian Infantry Division was authorized on 24 May 1940 under General Order 184/40, with the government's decision to mobilize nine infantry battalions for the formation announced to on 27 May 1940. Its headquarters was established at Camp Debert, , in 1941, and divisional headquarters was formally constituted on 10 June 1941 under Major-General L.F. Page as . The constituent brigades concentrated at separate training sites: the 10th Infantry Brigade at Nanaimo Camp, , in October 1940; the 11th Infantry Brigade at Camp Borden, , in October 1940; and the 12th Infantry Brigade at Camp Valcartier, , in March 1941, relocating to Camp Borden in June 1941. Conversion to an armoured formation commenced in early 1942, with official redesignation as the 4th Canadian (Armoured) Division occurring on 26 January 1942 per General Order 132/42. This shift addressed Canada's need for additional armoured capabilities, drawing on non-permanent active militia units re-roled from infantry roles, such as the South Alberta Regiment. Initial training in Canada emphasized basic armoured operations using domestically produced Ram tanks, though progress was constrained by the division's lower priority for equipment and personnel compared to earlier formations, leading to transfers of units like the 17th Field Regiment to the 1st Armoured Division. Elements of the division deployed to the in late , with convoys arriving at the Clyde on 31 August, 6 October, and 4 November. in , spanning from arrival through July 1944, focused on collective armoured tactics, achieving squadron-level proficiency by 15 1943 and advancing to and divisional exercises thereafter. Regiments participated in joint manoeuvres, including war games with the Polish 1st Armoured Division, to refine integration and prepare for North-West operations. Major-General F.F. Worthington assumed command on 2 , overseeing this extended preparation phase amid resource limitations typical of later-mobilized Canadian divisions.

Campaigns in North-West Europe

The 4th Canadian Armoured Division (4 CAD) entered combat in North-West Europe on 29 July 1944, deploying to as part of II Canadian Corps following the initial D-Day landings. It relieved elements of the 3rd Canadian Infantry Division east of the Falaise road and participated in the later stages of the campaign, including from 7-10 August, which aimed to break through German defenses south of toward Falaise. During Totalize, the division advanced through heavy resistance at positions like Cintheaux and Hautmesnil, suffering significant tank losses, with the Dragoons alone losing 47 tanks and incurring 112 casualties. In (14-16 August), 4 CAD supported the closure of the , capturing Damblainville on 17 August and advancing to Trun, where it linked with U.S. forces at Chambois on 19 August, contributing to the encirclement and destruction of much of the German Seventh Army. A notable action occurred at St. Lambert-sur-Dives from 18-19 August, where Major David V. Currie of C Squadron, South Alberta Regiment of Cavalry, commanded a mixed force that repelled counterattacks, destroyed or captured over 200 enemy vehicles, and took 2,100 prisoners, earning the for his leadership. The division crossed the Seine River on 26 August near Elbeuf, securing bridgeheads alongside the 3rd Canadian Infantry Division, then advanced rapidly to the , crossing it on 2-3 September despite logistical challenges. Following the Normandy breakout, 4 CAD shifted to clearing coastal areas, engaging in the from to to open Antwerp's port. It assaulted the at Moerbrugge on 8 , establishing a after intense fighting, and later supported operations at the Leopold , including failed crossings at Moerkerke (13-14 ) that cost 148 casualties. In Operation Switchback (21 onward), the division cleared along the -Terneuzen , while in October, it tackled the Breskens Pocket and participated in Operations Suitcase and , capturing Esschen (22 October), Bergen-op-Zoom (27 October), and Steenbergen (4 ), facilitating the reduction of South Beveland and islands. These actions involved amphibious assaults, use across canals, and heavy artillery support against fortified positions. During the winter of 1944-1945, 4 CAD held the Nijmegen Salient and conducted operations like clearing Kapelsche Veer (26-31 January 1945). In the Rhineland Campaign (Operation Veritable, February-March 1945), it assaulted the Hochwald Forest and Gap from 26 February to 4 March, facing fierce resistance in wooded terrain and mud, before clearing Veen (to 9 March) and Winnenthal (10 March). The division supported the Rhine crossing in Operation Plunder (23 March) and advanced into Germany from 1 April, crossing the Twente Canal (3 April), liberating Almelo (4-5 April), and pushing through Neuenhaus, Emlichheim, Coevorden, and the Ems River to reach Bad Zwischenahn by 30 April. Hostilities ceased on 5 May 1945, with 4 CAD having inflicted heavy losses on German forces across multiple fronts, though at the cost of its own inexperienced units learning through combat.

Tactical Achievements, Criticisms, and Key Personnel

The 4th Canadian Armoured Division contributed decisively to the closure of the between 18 and 21 August 1944, with its forces capturing Trun on 18 August and advancing to St. Lambert-sur-Dives, where a company of the South Alberta Regiment of Armour under Major David V. Currie repelled seven German counterattacks over 36 hours, destroying 12 tanks and 150 vehicles while capturing 2,100 prisoners. These actions, which earned Currie the , helped link with the 1st Polish Armoured Division and seal the pocket, leading to the destruction or capture of much of the German 7th Army and . In the subsequent pursuit, the division advanced rapidly northeast from , occupying Buchy on 31 August and reaching the east of by 2 September, supporting the Allied drive toward the . During the from early October to late November 1944, the division established bridgeheads over the Ghent Canal at Moerbrugge and assaulted across the using flame throwers and amphibious vehicles, clearing entrenched German positions and contributing to the liberation of Bergen-op-Zoom on 27 October while aiding in the reduction of the Breskens Pocket. These operations, conducted in flooded terrain against fortified defenses, opened the Estuary for Allied shipping to by 28 November, despite incurring 6,367 Canadian casualties in the campaign overall. Criticisms of the division's performance centered on command decisions and operational tempo. Major-General George Kitching, the division's commander since February 1944, was relieved on 30 August 1944 after Falaise, officially for delays in coordinating with U.S. forces that permitted some German escape from the pocket, though subsequent historical analysis has questioned the fairness of this attribution given the division's successes. Field Marshal Montgomery faulted the First Canadian Army's post-Seine pursuit, including the 4th Division's advances to St. Omer, as "badly handled and very slow" amid logistical strains and rearguard actions. In at the Hochwald Gap from 25 February to 2 March 1945, under Major-General Chris Vokes, the division's frontal assault through narrow, minefield-laced terrain defended by three German parachute battalions resulted in heavy losses—over 200 casualties in one battle group alone—and was later decried by veterans and historian Denis Whitaker as a "death trap" due to persistence despite bogged armor and intense anti-tank fire, implicating Vokes and II commander Lieutenant-General . Key personnel included Major-General George Kitching, who led the division through its Normandy debut and Falaise; Major-General Chris Vokes, who commanded from September 1944 to war's end and oversaw the and operations; Major David V. Currie of the South Alberta Regiment, awarded the for his Falaise actions; and Lieutenant-General , whose II Canadian Corps directed the division's engagements. Brigadier Robert Moncel commanded the 4th Armoured Brigade during key advances.

Post-War Dormancy and Reserve Evolution

Disbandment and Integration into Reserves

The 4th Canadian Armoured Division commenced shortly after on 8 May 1945, with remaining elements performing occupation duties in before repatriation to . The formation returned progressively throughout 1945, culminating in its formal disbandment in December 1945 as part of the broader reduction from wartime strength of approximately 780,000 personnel to a peacetime establishment of around 25,000 in the Permanent Active Militia. This process involved the release of most personnel through points-based systems prioritizing length of service and overseas time, with veterans receiving rehabilitation benefits including loans and job placement assistance under the Veterans Rehabilitation Act. Following disbandment, the division's constituent units—such as the 10th Infantry Brigade's regiments including The Lincoln and Welland Regiment, The Algonquin Regiment, and The Argyll and Sutherland Highlanders of Canada—were demobilized and reintegrated into the Non-Permanent Active Militia, the precursor to the modern . These regiments perpetuated the division's battle honors and traditions within regional reserve formations, contributing to the 1946 reorganization of the Canadian Army reserves into infantry and armoured brigades without maintaining a distinct divisional headquarters. This integration preserved unit identities amid fiscal constraints and a shift toward a smaller focused on commitments, rendering the 4th Division formation dormant until its reserve reactivation in 2013.

Reorganizations Leading to 2013 Reactivation

Following the of wartime forces after 1945, units associated with the 4th Canadian Armoured Division were perpetuated in the Canadian Army's (militia), integrated into a of 10 military districts that managed part-time soldiers across for territorial defence and augmentation roles. Unification of the Canadian Armed Forces in dissolved the standalone , placing reserve land units under Mobile Command's regional formations, which emphasized interoperability with Regular Force elements amid priorities. A pivotal reorganization in September 1991 restructured reserve administration by consolidating the prior five Areas into four Land Force Areas under Land Force Command, facilitating closer integration of Regular and Reserve components to support expeditionary commitments. The Land Force Central Area (LFCA), headquartered in , assumed responsibility for Ontario's reserve forces, commanding four brigade groups—31st (), 32nd (), 33rd (), and 34th ()—comprising approximately 6,000 personnel focused on , , and service support roles. This framework enabled reserve mobilization for operations like those in the former during the , where LFCA units provided individual augmentees and sub-units, testing the area's capacity for rapid force generation. Subsequent adjustments in the 2000s addressed demands, including enhanced training standards and equipment modernization under the Total Army concept, which sought to treat reserves as a scalable extension of the for missions in . By 2010, evaluations highlighted limitations in the area-based model, such as fragmented command and insufficient historical identity, prompting the Canadian Army Reserve Force Realignment Framework in 2013. The 2013 reforms redesignated the Land Force Areas as numbered divisions to revive divisional lineage, boost morale, and streamline command for better domestic and overseas surge capacity. LFCA was specifically renamed the , inheriting the shoulder patch and honours from its and II predecessors, while retaining oversight of Ontario's reserve brigades and integrating select enablers. This reactivation, effective throughout 2013, aligned with broader Army efforts to field multi-purpose land forces at varying readiness levels, emphasizing the division's composition for operations like and high-readiness battlegroups.

Modern Reactivation and Current Mandate

2013 Reforms and Operational Focus

In 2013, as part of a broader initiative to restore traditional formation names and enhance operational identity, Land Force Central Area (LFCA)—an administrative command established in 1991—was redesignated the 4th Canadian Division. This change, announced on November 5, 2013, by Chief of the Land Staff Lieutenant-General Marquis Hainse, aligned the structure with historical precedents from the World Wars while aiming to foster unit cohesion and readiness among reserve forces. The redesignation did not involve significant alterations to personnel or equipment but emphasized divisional-level command for better integration of regular and reserve components in , the division's area of responsibility. The primary operational focus of the 4th Canadian Division post-reform centers on generating and sustaining combat-ready, multi-purpose land forces at specified readiness levels to fulfill government-directed tasks, particularly in domestic and continental defense scenarios. Headquartered at Denison Armoury in Toronto, it oversees approximately 13,000 personnel, including over 5,800 regular force members, nearly 6,000 reservists, and Canadian Rangers, with a mandate to conduct general-purpose training for operations ranging from sovereignty patrols to disaster response and support to NATO or NORAD commitments. Emphasis is placed on reserve mobilization, enabling rapid augmentation of regular units for high-readiness tasks such as heavy equipment transport teams (HET) or search and rescue support, reflecting Canada's post-Cold War shift toward flexible, expeditionary-capable reserves rather than large standing armies. This structure supports causal priorities in force employment, prioritizing empirical readiness metrics like training cycles and equipment maintenance over expansive deployments, given fiscal constraints and the low likelihood of peer-level continental threats. The division's role remains administrative and training-oriented, with no dedicated combat maneuver brigades, focusing instead on integrating Ontario-based units—including elements at CFB Petawawa—for scalable responses to events like wildfires or floods, as demonstrated in periodic exercises.

Command and Leadership Structure

The 4th Canadian Division is led by a brigadier-general serving as commander, who reports directly to the at army headquarters in . This officer oversees the division's primary mandate of generating combat-ready reserve forces across , integrating capabilities where required, and coordinating with Joint Task Force Central for domestic operations support. The headquarters, located at Denison Armoury in , includes a (typically a ) handling operational planning, , and administration, alongside specialized staff officers for , operations, and personnel. As of September 2025, Brigadier-General J. Éric Landry holds the position of Commander, 4th Canadian Division, having replaced Brigadier-General C.I. Oberwarth, who departed the role in August 2025 to assume duties as , Digital Services Group. Landry's appointment aligns with annual senior officer rotations announced by the to maintain operational continuity and expertise in reserve force mobilization. The commander's dual role as head of (Central) emphasizes readiness for both international deployments and national emergencies, such as . The Formation Sergeant-Major, a , serves as the senior , advising the on enlisted matters including training standards, discipline, welfare, and morale across the division's approximately 13,000 personnel (including reserves). Recent updates to this , such as the December 2024 appointment of a master promoted to the role, reflect ongoing efforts to align with evolving reserve commitments. Subordinate leadership flows through four regional Canadian Brigade Groups—31 CBG (headquartered in ), 32 CBG (), 33 CBG (), and elements of adjacent groups—each commanded by a responsible for unit readiness within their area. These brigades integrate , , engineers, and service support units, enabling scalable force generation under division-level direction. Quarterly command team reviews and annual exercises ensure alignment with priorities, such as high-readiness taskings for or UN missions.

Present-Day Organization and Capabilities

Brigade Groups and Reserve Units

The 4th Canadian Division commands three Canadian Brigade Groups (CBGs), which serve as primary reserve formations responsible for the mobilization, training, and administration of Army Reserve units across . These brigade groups align with geographic regions—southwestern, central, and —and collectively encompass over 50 reserve units, including , , , engineers, signals, service support, and medical elements. 31 Canadian Brigade Group, headquartered in London, Ontario, oversees reserve units in southwestern Ontario, such as the 1st Hussars (armoured reconnaissance regiment with squadrons in London and Sarnia), 4th Battalion, The Royal Canadian Regiment (light infantry in London and Stratford), 31 Combat Engineer Regiment (engineers in Windsor, St. Thomas, and London), 31 Service Battalion (logistics in London), and 31 Medical Company (medical support in London). The brigade focuses on high-readiness capabilities for domestic operations and augmentation of regular forces, with approximately 2,000 reservists. 32 Canadian Brigade Group, based in Toronto, Ontario, manages units in the Greater Toronto Area and central Ontario, including the Royal Regiment of Canada (primary reserve infantry in Toronto), 48th Highlanders of Canada (infantry in Toronto), Queen's Own Rifles of Canada (infantry in Toronto), Toronto Scottish Regiment (infantry in Toronto), 32 Combat Engineer Regiment (engineers in Toronto and North Bay), 32 Service Battalion (logistics in Toronto), and 7 Toronto Regiment, Royal Canadian Artillery (field artillery in Toronto). It supports rapid deployment for operations like disaster response, drawing from urban reserve pools exceeding 3,000 personnel. 33 Canadian Brigade Group, headquartered in Kingston, Ontario, covers eastern Ontario with 16 reserve units, such as the Princess of Wales' Own Regiment (light infantry in Kingston), Stormont, Dundas and Glengarry Highlanders (infantry in Cornwall and Prescott), Governor General's Foot Guards (ceremonial and light infantry elements affiliated in ), 33 Combat Engineer Regiment (engineers in and Kingston), 33 Service Battalion (logistics in ), and 33 Signals Regiment (communications in Kingston). The group emphasizes interoperability with regular forces at bases like , maintaining around 2,500 reservists for high-intensity training exercises. These brigade groups integrate with the division's support elements, including the 4th Canadian Division Support Group, which provides logistics, signals, and garrison services to enable reserve units' operational readiness. Reserve personnel from these formations have contributed to missions such as in (training Ukrainian forces since 2015) and domestic responses to wildfires and floods, demonstrating scalability from individual augmentation to battalion-level deployments.

Training Facilities and Recent Commitments

The 4th Canadian Division Training Centre (4 CDTC), located in Meaford, Ontario, serves as the primary training facility for both and soldiers within the division's area of responsibility, which encompasses west of Peel . Established to deliver foundational military skills, the centre focuses on basic soldier qualification courses, including , weapons handling, offensive and defensive operations, and tactics, techniques, and procedures. It supports an average of over 600 personnel in training each week and accommodates international partners such as units from the , , , and , as well as non-military organizations like police and emergency services for joint exercises. The facility includes extensive live-fire ranges, such as the Paardeberg Anti-Tank Range, training areas for maneuver, accommodations, and logistical support services. Additional training infrastructure supporting the division includes Canadian Forces Base Kingston on the north shore of for specialized infantry and operational training, and various regional ranges such as those at Cedar Springs, Winona, and Windsor Armouries for weapons qualification and small-unit drills. The 4th Canadian Division Support Base Petawawa provides garrison-level sustainment, enabling focused training by handling administrative, maintenance, and logistical requirements for units conducting exercises in the region. Recent commitments emphasize readiness for domestic operations and high-readiness tasks under the Canadian Army's Managed Readiness Plan. In December 2023, chaplains from the division participated in Exercise RESILIENT SPIRIT, a focused training event to enhance spiritual resilience and operational support capabilities amid joint operations command scenarios. In May 2024, elements of Joint Task Force Central—commanded concurrently by the 4th Canadian Division—conducted an emergency response exercise originating from northeastern sites like Jack Garland Airport, simulating rapid deployment for disaster relief under Operation LENTUS protocols. The division's reserve formations routinely contribute to Operation LENTUS responses, including flood and wildfire assistance in , with personnel from units like the 31 Canadian Brigade Group augmenting evacuations and infrastructure support, as seen in recurring activations through 2024 and into 2025. These activities align with the division's mandate to generate combat-ready forces for general-purpose operations, including potential high-readiness rotations for commitments.
