Here is a quick rundown of final 2014 attendances for Canadian high level (Minor League Baseball, independent baseball and collegiate summer leagues) baseball teams. All numbers all for regular season games only. The rankings include the team name, league, average attendance and the number of openings (ie double-headers count as one opening).
Note: the Vancouver Canadians are currently the only affiliated minor league team. The American Association and CanAm Leagues are both independent professional leagues. The Western Major Baseball League, West Coast League, Northwoods League and Pacific International Leagues are all collegiate summer leagues.

The Pacific International league does not track attendance. Canadian teams include the Kamloops Sundevils, Langley Blaze, Burnaby Collegiate Bulldogs and Trail Orioles.
Would be interesting to see where Maritime-based teams would rank on this list. I believe well-marketed teams in Halifax and Moncton would rank close to Quebec, or at least outrank the Aigles, if they were part of the CanAm League. There is no reason to believe a well run summer league in the Maritimes could overdraw the WMBL in the big six markets of the Maritimes (Halifax, Moncton, Saint John, Fredericton, Sydney and Charlottetown).
