Below are a couple of Brunch spots I've recently tried in Toronto.
First up - School Bakery & Cafe in Liberty Village - http://www.sbcto.com
Great space, gorgeous dishes, good food. It gets pretty busy so go early if you don't want to wait.
The Queen & Beaver Public House on Elm St. - http://queenandbeaverpub.ca/
Another great space, delicious food but definitely lacked on the sides, actually there were no sides, which was odd. Order some fries if you're still hungry.
Niche Coffee & Tea Company on Queen St. West - http://www.nichecoffee.com/
We ate on the back patio on a warm fall day. Poached eggs on corn bread....yum!
Musa on Dundas West. (sorry for photo quality, taken on blackberry)
Interesting and creative dishes, lots of food but no need to rush back.
