they are majestic but I wouldn't like to run into them - yes, I wouldn't want to run into them in the Canadian wilderness. It's often claimed that they're fearful of humans but I'm an unlucky so-and-so. Wolves regularly run down and kill prey many times my weight, with greater strength, speed and endurance than I have.
Where I live in Poland (backyard is Kampinos National Park) the boars are viewed as a nuisance by the local farmers - any local wolf packs will hunt the boars.
we have re-introduced lynx to deal with the problem of too many deer - here in the UK, we also have too many deer. They are culled annually. Some scientists are discussing re-introducing lynx into the UK to deal with this same problem. I think the UK could sustain a population of lynx but not wolf. I don't think we have enough wilderness for wolves here.
