Coyotes are very common throughout Ontario, Quebec and other provinces. They're shy and careful, and just not often seen, but they're always around unless you're right in a city.
The one in the back looks like it might be a coyote-dog hybrid, which is also becoming increasingly common - and concerning. Dog crosses behave differently, are less predictable, and less cautious about humans and human dwellings. They can also be quite large, like in the 60-80 lbs. range. A few like this have been found in the Rouge Valley in Scarborough, the fringes of Toronto.
I'd never be nervous about pure coyotes. They do not attack people, at all, ever (unless rabid, but that's exceedingly rare these days). Here, they don't even go after livestock. They keep a very respectful distance during the day, though we hear them every night. We have large family groups here, sometimes with close to 30 voices. This time of year we hear their cubs yipping, too. Even so, we free range our chickens all day, with zero incidents in over six years.
Anyway, very nice shot, and a nice sighting for you. Don't be worried about them though.
