Canadian Actors/Actresses of the Classic Era

Raymond Burr was *born* in Canada, though I think he was moved to the US when he was still a kid. And his mother, I think, was US-born-&-raised as well. But his father was Canadian and I have run into more than one person who has said that he should be considered a "Canadian actor" and not rather a "Canadian-born American actor". He also did go back and forth between the two countries doing theater work, and making visits with hospitalized vets during WWII. Don't recall what his official citizenship status was - Canadian, American or Dual, if that would matter.
