"So there was a war? Tough ... if you were a French Canadian in Montreal in the early 1940s, you did not automatically believe that this was a just war ... we tended to think of this war as a settling of scores among the superpowers." - Pierre Trudeau
Actually, I was just reading an Osprey Publishing book titled “D-Day Beach Assault Troops,” published in 2017.
It references a lot of Canadian units, some French. For example, on page 38 there’s a pic of soldiers from Le Regiment de la Chaudiere waiting in their landing craft.
As to French Canada’s overall contribution to the war effort, I admit I have not studied this closely. I get the impression that the Quebecois were more engaged in WW2 than the Great War, but that’s just an impression.
