SW store in Toronto?

[Oilers]

I am going to Toronto for a few days this Easter long weekend. I wonder if you would recommend a couple SW stores that are worthwhile for me to check out. Also, have you tried bringing live stocks on to the plane with Air Canada?
PS Any place/activity would you recommend for a family in Toronto? I am planning to check out Niagara Falls, the Hockey Hall of Fame, CN Tower, Chinatown.
