Canucks and Jets fan
It depends on where in Canada. West coast has skewed Seahawks with their rise to prominence in the last 8 or so years, central tends to fluctuate between a hodgepodge of teams (Steelers, Cowboys, Packers, Pats, etc. Vikings definitely seems to be most prominent) and then the east coast is similar.
Growing up in the Peg, you had tons of Vikings fans mixed in with Packers fans. My uncle is a die hard Washington Football Team fan, I grew up in the Raiders and yourself had the Dolphins.
