Was that an old Canadian flag in captain's quarters?

That part at the beginning when Sutherland's talking to the photo of himself (probably lamenting ever signing up for this movie hehe) was that the old original version of the flag of Canada (I said FLAG people)? I didn't get a good look but it was red (check) had the union jack in the upper left corner (check check) and a shield to the right of centre. Or is that a provincial flag, Ontario maybe?
