Hi, I'm headed to Toronto in about a week (August 21st) for an extended weekend (Thursday-Sunday). I'll be there with a handful of friends and we're looking for some daytime activity ideas. I'm specially interested in things unique to Toronto, if possible.
Activities can range from dim sum to BuskerFest to rock climbing the CN tower :)
The CNE will be going on at that time (if you like big fairs, it's a true Toronto institution) and also Buskerfest, like you mention.
For something quieter on a sunny day, take the ferry to the Toronto Islands for a walk, a picnic, or just enjoying the green spaces and beaches by the lake. You can also rent bicycles.
For a different atmosphere, head out to the Distillery District which is a pedestrianized zone lined with historical buildings converted into unique shops and restaurants.
For cheaper food, check out the St. Lawrence Market which is an attraction in its own right. (It's closed Sunday and Monday.)
At the foot of Jarvis St, south of Queen's Quay, is Sugar Beach, an urban beach easily recognizable by its pink umbrellas. It's a fun hangout spot in good weather.
Have fun! :)
Mentioned in this answer:
Definitely check out the Distillery District, it's full of galleries and interesting cafes, we had a great time exploring there this summer.
I found that recommendation and a few other interesting places on this guide that we at WhereFare have complied here: https://www.wherefare.co/guide/2210711903405677?source=f&sinfo=trp
