Being new to Toronto (again) we are so surprised that Toronto offers free admission to swimming pools. One of the best in the city is at Regent Park aquatic centre. This building looks very new. The whole area around it is great for families. Nice green space. Kids playground with soft rubber ground. Inside is even more impressive. The pool is rather small and it does get very crowded on Saturday when we went. The change rooms are large and the universal change room is great for parents and kids.
Inside there's lots of great detail. Life vests are readily available for young kids. Floaters are plentiful. There's fountains and sprays going into the pool (not like a splash park though).
Best part: the shallow pool is HEATED! So nice. The other deeper pool is not. There's a diving board, swinging rope and even a water slide. The place is surrounded by windows and let's in so much natural light. I still can't believe this is free in Toronto.
Only minor negatives is that is gets really busy (too be expected) and the washrooms are a bit dirty: Bring your sandals!
