There are definately people that hunt them, just like coyotes... You're essentially going out calling.
(I mean, I know people who bait FOR wolves, but one of them recently got charged with "using dead stock as bait" to the tune of $8000 in fines... you can't bait wolves successfully using table scraps IMHO, cuz they eat like horses - or better yet, they eat horses! nuk, nuk, nuk

) They're biologically adapted to eating 50 lbs of meat at a time, and then not eating for days at a time.
in the areas of ontario where "development" meets bush, there are wolves and coyotes, but generally more coyotes because the wolves aren't into developed areas that much. Coyotes thrive on that "border area of development and bush. In rural ontario, if you want to go calling, (my .02): you go to an area likely to hold wolves or coyotes, then you start looking for tracks... If there are lots of coyote tracks, there are likely no wolves...same deal with fox.
there are a couple good sites on the subject. Google "predator hunt canada" (It's the best site on the internet

after CGN of course

) and join up to read.
cheers to you.
