Tim Hortons is on this list but is majority owned by Americans (Burger King, specifically IIRC).
It’s owned by Restaurant Brands International which is headquartered in Toronto, but listed in both Toronto and New York stock exchange. The majority owned is 3G capital, a Brazilian firm.
That info is outdated actually, 3G sold their shares in 2019 apparently, now the biggest shareholders group are american
