Any suggestions on interesting and or must dos in Toronto? Will be there for a 3 day weekend in early September. Two adults, no kids.

Within town: Art Gallery of Ontario, Royal Ontario Museum, Ontario Science Centre (kids would have liked it), CN Tower, Skydome among the "big" attractions.
www.globeandmail.ca and www.torstar.ca might have some clues as to cultural offerings.

This source should be a help too. Take in a concert, go to the theatre, watch a game, drive to Niagara, visit the casino. Decisions, decisions...

There's a 1/2 price same day theatre booth, I believe its on Yonge St... I have found an occasional good show there.

if u have never been, absolutely must take a drive to niagara... one day trip is enough, so u have two days left in clean friendly toronto...
do u know already where will u be staying?

Take in the Mamma Mia Show at the Royal Alexandra Theatre. Inexpensive on Sat & sun afternoons. Check with half price booth suggested above.

This is a GREAT SHOW. Has been extended to 1 years from the original scheduled 3 months.

Catch the Air Show during the Canadian National Exhibition (CNE) during Labour day weekend

Also, if you like ice hockey, be sure to check out the Hockey Hall of Fame.

Yes! In my book, the Hall of Fame is the top cultural attraction in the country.

Good food scene, great restaurants. Nice mix of Theatre.

And if you come the weekend of Sept 8-10 you can take part in the second Toronto/Red Green Deux:

CN Tower is an obvious and pretty cool thing to visit. I enjoyed that when I went to Toronto. I also went downtown to Eaton Centre and walked around there for the shops, etc. Toronto's a really nice city.. you'll enjoy it.

Other than on Yonge St. around the Eaton Centre, here are four other areas to wander through:
- the Harbourfront: some upscale shops, antiques, entertainment
- Queen St. West (west of University Ave.): an eclectic variety of stores, bars and other entertainment
- the Beach (Queen St. East - east of Woodbine): another shopping & walking area. You'll have to take a streetcar to get there from Yonge St. area
- Bay, Bloor, Yorkville area: the REALLY upscale stores, fashions and restaurants.

i like the yorkville area the best, stayed at the four seasons everytime, and intercontinental one time just across the street....
nice backstreets to walk around, lots of art galleries, boutiques, etc.
love the Swiss Chalet restaurant, IMHO, the secret recipe sauce makes theirs the best rotiserrie chicken in the world!

Theatre. Look for Primadonna, The First Farewell Tour, Mary Lou Fallis' one woman show. Even if you do not like opera, it is one of the funniest shows you will ever see. Unfortunately, is it only due to run to August 5, but if it is held over, you should not miss it.

Attractions: Labour Day Weekend (note the spelling ) is CNE time. (The Canadian National Exhibition). Well worth a visit. Hsi chang is spot on with the airshow recommendation. The Snowbirds invariably perform, and usually the Blue Angels and the Red Arrows come, as well.

Skip the Skydome and CN Tower, unless you are a big fan of urban landmarks. The Skydome is a rotten venue for baseball--there is no intimate feel like you get in more open parks.

Consider taking a ferry over to the Island. A nice urban-park feel. Pleasant place to spend a sunny, weekend afternoon.

Museums: Pick the one that suits your tastes. For fine arts, the ROM. For decorative arts, why not visit Casa Loma? For Sciences, the OSC is great fun. Obviously the Hockey Hall of Fame is a shrine to Canada's National (Winter) Sport.

Dining: A wealth of choice. Generally the quality at the top end is almost as good as Montr�al. The variety is every bit as broad as New York. Check the local paper for reviews of new hot spots. Do not eat at the CN Tower. If you want food with a view, try Canoe on top of the TD Tower.

Shopping: Yorkville for the highbrow stuff (esp. Holt Renfrew--the Flagship Store), Queen West for the fun stuff (drop by the CityTV studios while you are there).

People watching: Queen West (the Trendies), Yorkville (the Yuppies), Yonge (the Tourists), Church and Wellesley (the heart of the Gay Village)

Have fun!

Isn't that the Park Hyatt across the street from the Seasons?

There's a great pub nearby called Lord or Duke something.
