Farley Mowat served in the Canadian Army in Dubya-Dubya Too, and wrote some about it, but i don't know if was collected into a single book. I'm not sure if he wrote enough about it for a book.
There is an excellent book on Canada's military experience which is not quite what you've asked for, but which you might enjoy entitled
Fighting for Canada: Seven Battles, 1758-1945, by various authors, and edited by Donald Graves. This book was so popular that another has been compiled,
More Fighting for Canada: Five Battles, 1760-1944. You can read about it at the
Fighting for Canda web site.
