[6] The 97th Regiment (Algonquin Rifles) recruited to its full active strength and supplied 12 officers and 251 other ranks to the 15th Battalion, CEF.

The battalion was mobilized on 5 July 1916, trained at Camp Borden in Angus, Ontario, during that summer and fall of 1916, and embarked for England on 1 November 1916, with a strength of 1,004 men.

The regiment was transferred to Niagara-on-the-Lake and assigned guard duty on the Niagara River and the Welland Canal in November 1941, before finally being asked for their first draft for overseas enforcements on 14 January 1942.

In February 1942, the regiment was transferred to Newfoundland and assigned protection duties at Torbay Airport and Cape Spear.

In January 1943, the regiment was chosen for operations overseas, was moved to Debert Camp in Nova Scotia and, for administration purposes, was assigned to the 20th Brigade of the 7th Canadian Infantry Division.

The regiment embarked on the RMS Empress of Japan in Halifax on 10 June 1943, and sailed the following day for England with a complement of 4,500 troops.

The morning of 25 July, all four companies of the Algonquin Regiment landed on Juno Beach where, in the following days, learnt of their ensuing mission to support the 4th Canadian (Armoured) Division in closing the Falaise Gap.

[10] Leading up to 31 August, the Algonquin Regiment, moving within the 4th CAD, were tasked with filling the gap to the south at Hill 240, fighting alongside the 1st Polish Armoured Division.

The fighting, all day and suffering multiple setbacks resulting in numerous casualties across all the regiments, ended 10 September with the Allies across the Ghent–Brugge Canal after holding back the German counterattacks.

[12] A few days later the attempt of the regiment to cross the Leopold Canal was successfully repelled at Moerkerke by the German 245th Infantry Division.

Over the next couple of months, the Algonquin Regiment continued to fight, as they had been the entire war, under the 4th Division, crossing the Rhine with the last round-up (16 April–4 May) and cease-fire called just past Rastede, Germany.
