I bought one of the AC flight passes that were offered and may plan a day trip for a Saturday, sometime in the next two months.

Any suggestions of things to do? Have already seen the CN Tower, Skydome, Hockey Hall of Fame.

Same question goes for Vancouver, Ottawa and Montreal.

Your assitance is appreciated. Thank you

There are pages for Vancouver and Montreal as well, but not Ottawa.

To add some for Toronto;

St Lawrence Market on Saturday, for open market

WinterCity festival,
and Winterlicious prix fixe menus

Hope you enjoy your trip to Toronto :)

If it's winter time - Head down to union Station. Then use the underground mall to walk north and get out at every main east-west street and explore the area.

Just a partial idea

@Front street - King eddy hotel or if you go east and it's before noon - try the St Lawrence Market
@King st- CBC HQ, Theatre district, Roy Thompson hall
@Queen st- Walk west towards Spadina and see the fashion district or the latest in youth culture/trends. Visit City TV
Queen to Dundas - Explore Eaton Centre
@Dundas - @ Yonge St at it's busiest Fast becoming the intersection in T.O. If you go west a few blocks you'll hit chinatown. Little italy is a few blocks NW of there if you want.
@College - Maple leaf gardens?
@Bloor - Yorkville, or if you go east (by Cab) the danforth and Greek town.

Just to add a few more:

Bata Shoe Museum: 327 Bloor
Honest Ed's Bargain (aka Garage Sale Indoor store): Bloor & Bathurst

If coming this or next month, try to do something warm inside and stay out of the outdoor cold.
