Have fun in Toronto, Cillaliz. That's one of my favorite cities...love it there!
Suggestions?

Also, Second City is fun.
And they have a terrific symphony. You can get a cheap "rush" ticket at the last minute, @ $20 on the day of the concert. Get there early, they go on sale at 10AM. It's fun to get a seat behind the orchestra. I haven't seen their current conductor but used to go a lot when Andrew Davis was there.
The zoo is nice, too!
Food-wise, they have a GREAT big Chinatown, pretty much any place with dead stuff hanging in the windows is a good bet.
Our exec producer for the baseball film lives in Toronto so I'll check with him, although I suspect he goes to fancier restaurants than I do.
Another thing I like is that I've worked there at all hours and it always seems safe to be walking around at night. I could have a false sense of security, though.
The Distillery District is supposed to be pretty cool; I haven't been there since it was developed but hear good things about it.
Go shopping in Yorkville if you have too much money. And look for the little black squirrels in public parks. They keep their eyes peeled for people using the water fountains and then hop up and drink the rest of the water after you're done!
