After the war, the battalion disbanded, and in the 1920 re-organisation of the Militia, in the wake of the work of the Otter Commission, a new regiment was created amalgamating the 50th Regiment and the 88th Regiment Victoria Fusiliers, and named "The Canadian Scottish Regiment". The title "(Princess Mary's)" was appended in 1948 by permission of King George VI and Mary, Princess Royal and Countess of Harewood, who had consented to become colonel-in-chief of the regiment in 1930, being also colonel-in-chief of the Royal Scots (The Royal Regiment) since 1927, and to whom the Canadian Scottish had been allied in 1927.
