If you are looking for an authentic Canadian art experience, make sure to put the McMichael on your bucket list. I visited regularly when I lived in Toronto and now my wife and visit every time we are in the Toronto area.
Yelp Tip - If you have an Associate Membership with the Albright-Knox art gallery, you have reciprocal privileges at the McMichael for free admission to the gallery! That is almost a $40 savings for a family visit.
The art gallery features masterpieces from the Group of Seven (the quintessential Canadian landscape artists), and other amazing Canadian artists such as Emily Carr and Norval Morriseau. They also recently had ana amazing Matisse exhibit!
Once you've taken in all the great artwork, head outside to the beautiful grounds which are connected to the Humber Valley Trail network. Parking is a very reasonable $5 Canadian and they also have a very nice gift shop which sells everything from maple syrup to jewelry.
