Blue Jays have a much healthier prognosis than the Marlins. Once upon a time, just about everyone in Canada outside of Ontario rooted for the Expos...now some are Nats fans, but the great majority of Canadian baseball fans root for the Jays. That's a pretty huge fanbase, even if it is distributed over a huge geographic area.
Studies have shown that they have one of the smallest fanbases in all MLB.
Canadians don't give a crap about baseball.
