Looking into franchise opportunities

Being a Canadian Tire Dealer is certainly my goal.  However, other franchise opportunities are coming to my attention.  I think it would be great to run a bakery; or a kids lunch program; or a tutoring company; or a natural supplements store; or even a Tim Horton's....  AAHHHHH!  There is too much out there!  I'm going to have to pull out my New Venture book and build a spreadsheet with all the relevant analysis points.
