Apple Maps is fantastic in Canada, or at least the Toronto area. Even in cottage country hours from urbanity has excellent directions and 3d buildings and structures.

I'm in Europe. Apple Maps have served me very well in my country as well as in a few other European countries I've visited.

I'm currently visiting Poland and Estonia, and have been using Apple Maps to walk from place-to-place. It's been working well for me—I have yet to get lost using it, and it seems to be giving me good directions.
