Here is an excellent article by J.L. Granatstein the author of “Canada's Army: Waging War and Keeping the Peace” (2002).
An excerpt from the this article relates to my own interest in the veterans of Southwestern Ontario:
“Consider the case of the 1st Infantry Battalion (from Southwestern Ontario) of the First Canadian Division. Its normal strength was some 900 officers and men, but this one unit saw 6,500 men pass through its ranks. It lost 49 officers and 699 men killed, and 126 officers and 3,055 men wounded. In other words, almost 4,000 men of the 1st Battalion did not return to Canada in one piece, and such numbers likely omit the stress casualties, who woke up screaming for years to come.”
