It might be good to remember that the wolves in southern Ontario are not Gray wolves, they're Eastern Canadian Wolves, which _do_ hybridize with coyotes.
Gray Wolves are a completely different story. They _don't_ hybridize, and they're _huge_ compared to a Coyote. The first time I saw a Black-morph Gray wolf in Manitoba, I thought I was looking at a black bear.
The Algonquin wolf page has a pretty good writeup.
