5th Canadian Division

The 5th Canadian Division of the Canadian Corps was formed during World War I under Major-General Garnet Burk Hughes. The 5th began assembling in Britain in February, 1917, but was broken up in February 1918 before it was fully formed. The Division adopted a coloured formation patch identical in design to that worn by the four combatant divisions of the Canadian Corps. Its men were used as reinforcements for the other four Canadian divisions, helping to maintain the over-strength Divisions of 22,000–25,000 with more than 100,000 men total. It was reactivated in 2013.

The 5th Canadian (Armoured) Division was a Canadian division during World War II. It was formed on 27 February 1941 as the 1st Canadian Armoured Division. However it was later redesignated as the 5th Canadian (Armoured) Division on 26 June 1941. Following its redesignation from 1st Canadian Armoured Division, the bulk proceeded overseas in one main convoy, arriving in the United Kingdom at the end of November 1941.

The 5th Canadian (Armoured) Division spent two years of the war uneventfully in the United Kingdom, before finally transferring to the Mediterranean theatre in November 1943 to join the 1st Canadian Infantry Division as part of I Canadian Corps, under command of the British Eighth Army. The division moved without its tanks and vehicles, inheriting heavily used equipment as a legacy from the veteran British 7th Armoured Division ("The Desert Rats") who they relieved on the Italian Front. The majority of the vehicles were completely worn out, having first been issued in North Africa or were two-wheel drive–useless in Italy. It took several months for the division to be fully equipped with new vehicles, including M4 Shermans. Only the 11th Canadian Infantry Brigade was committed prior to 31 January 1944.

The 5th Armoured took part in the Italian Campaign until the end of 1944, seeing notable action on the Hitler Line after the Allied breakthrough at Cassino in May 1944 and also during Operation Olive on the Gothic Line in August 1944. During the latter battle its single infantry brigade was augmented by a second, which was raised using reinforcements and units serving in other roles. Among them was the 4th Princess Louise Dragoon Guards–1st Canadian Division's armoured reconnaissance regiment. As with other Allied armoured divisions in the Mediterranean, local resources were used to establish an additional infantry brigade, the 12th Canadian Infantry Brigade. Based on the colour of its shoulder patch, the division became known as the "Mighty Maroon Machine".

In January 1945, the division, together with the 1st Canadian Infantry Division, as part of Operation Goldflake, moved by truck, train, and naval transport to Belgium via Livorno and Marseille. After arriving on the Western Front, it disbanded the 12th Brigade, and re-equipped to join the First Canadian Army in time to participate in the final advance into Germany.

In April 1945, the Irish Regiment of Canada was assigned to Operation Cleanser in the Netherlands. They had to liberate the route from Arnhem to Harderwijk. This unexpectedly resulted in a fierce fight at the Battle of Otterlo.

Eastern Command

In 1946, the Canadian Army was divided into five regional total-force commands that were responsible for all Active Force and Reserve Force within assigned regions. The Canadian Army’s Eastern Command was headquartered in Halifax with responsibility for all Atlantic provinces, which later included Newfoundland when it joined confederation in 1949. Eastern Command was also mandated to generate 5th Canadian Division headquarters and division troops in the event of an emergency or other mobilization.

Following Unification of the Canadian Armed Forces in 1968, the Army Reserve was reorganized into militia districts and total force regional commands no longer existed.

Land Force Atlantic Area (1991–2013)

Land Force Atlantic Area (LFAA) was created on 1 September 1991, taking command of what was previously the militia areas and the Regular Force Army units and formations in Atlantic Canada. At that point in time, the Militia Areas ceased to exist, and the subordinate Militia Districts were reorganised. On 4 September 1992, the Combat Training Centre was allocated to LFAA.

Later that decade, the reserve force districts were again reorganized into two Canadian Brigade Groups. LFAA was the formation responsible for Canadian Army operations in the Canadian provinces of New Brunswick, Newfoundland and Labrador, Nova Scotia, and Prince Edward Island and was headquartered at Canadian Forces Base Halifax.
