Himself and I have been in Toronto, Canada, a couple of times on 11th November, and it is certainly commemorated there. Poppies everywhere - we had a couple with us that a friend had made before we went, our Canadian DIL requested them so we left them with her - poppies for sale in the weeks leading up to 11th November. Displays in shop windows....the music shop on the corner (now sadly closed, as the owner retired after 50 years) had a display of memorabilia, including the battle jacket worn by the owner's father in WWII. There was even a music evening there singing songs from war years, which I was able to join in - they let me borrow a ukulele.

So yes+, very much in Canada.
