Not to get off topic, but the wife & I visited Toronto back in 2018. We found a nice little hipster bar with live music called Handlebar. https://thehandlebar.ca/ Also http://bangbangicecream.ca/ was really good, and I think just down the road from a record shop, Rotate This, I think is the name. I don't know if any of these would qualify as "must see" but it was fun!
@BjorgenFjorgen We haven't booked a room yet. Staying the night on the Canadian side of Niagara Falls tonight then booking Toronto and driving there tomorrow. Appreciate all of the suggestions! @Mather, appreciate the invite to the murder basement and frogurt .
