Try "Canoe" for authentic Canadian cuisine and wines, if fine dining is your preference. The area of Queen St West is a MUST to visit, check Yelp for restaurant recommendations in this funky central community, lots of creative cuisine.

The revolving restaurant at the CN Tower for the view, do lunch there.

Search under Canada - Toronto right here for SPs. Lots of good current reviews.

Avoid Backpage, it's a minefield, spammed by Asian agencies.

My personal favourite Toronto agency is Select Company.

The top 100 tool on TER is the best tool I have seen anywhere for finding top quality reliable SPs in large Canadian cities.

Depends on what kind of food you like and where you're staying.

But The Grill on the Fifth is pretty great though. Definitely worth looking up.  

Hope you have fun.
