I drive regularly in Northern Ontario and see roughly one moose per year on average. I have seen a mother and calf once. These are mostly just quick sightings off the side of the road, though the mother and calf were crossing (fortunately I was on a gravel side road and going slowly).
If you really want to see moose, go to Newfoundland. On our last trip, we saw 11, including 9 in one day and 5 in one camera field. There was a huge bull adjacent to the parking lot at L'Anse Aux Meadows that was munching away just a few feet from us.
We saw a pine marten in Algonquin Park a couple of years ago. It was very tame, initially sitting on a branch beside the parking lot for a trail and then later puttering around the parked cars, looking for morsels.
Of the larger Canadian land mammals, I have not seen a cougar, lynx, polar bear, grizzly bear, musk oxen, wolf, wolverine, fisher, Dall's sheep, pronghorn antelope, and mountain goat (seen the last two in the U.S.).
