I was lucky enough to hike the Long Range Traverse with my family a few years ago. It is a truly beautiful area. Western Brook Pond was gorgeous, but my favourite shot is of my dad standing above Ten Mile Pond.
Now for some Ontario:

Finally, I know this is supposed to be about Canadian places, but I just came back from my annual pilgrimage to the Red River Gorge in Kentucky, and in the spring and fall it might as well be Canadian seeing as so many of us head down there. It's possibly one of my favourite places in the world; world-class climbing, beautiful scenery, and a fantastic vibe.
