Are you mocking my suggestion plaw? Seriously though, the population of Vancouver is roughly 2.5 to 3 million, Ottawa 1.5 million+, Calgary and Edmonton about 1.2 million each, and Winnipeg nearly a million. Granted the #1 sport in each of the cities is Hockey and likely will be for the next century or two, I think that cities that are that big can support a Major League Baseball franchise, although Montreal a city of nearly 4 million people could not so I could be wrong.
