If you are lucky enough to get Iron on tundra hills you could potentially turn that into a lot of extra gold through diplomacy.
The strategy for Canada appears to me to be: Settle areas that are unviable for everyone else, play the diplo game, linger around until late game and then destroy everyone in a Diplo or Culture victory. Also, I think Canada will actually be a good civ to build holy sites and go heavy for faith with now. Faith, in general, is better now that you can use Moshka to buy districts with it. Since Tundra areas are usually not particularly productive, all those "free" hammers will be needed. Dance of the Aurora seems like an optimal pantheon with Canada. Later in the game, you'll have all that faith to turn into Rock Bands for tourism and a little extra Diplo favor to boot.
