I'm not who you were talking to but Toronto Island and Scarborough Bluffs are both neat places though I've only been in the summer. The immersive Van Gogh exhibit was pretty cool and I'd think kids would like it. Think it was like 45 minutes or so (social distancing and limited occupants were enforced when I went). I haven't been but there are community skating rinks here and there and sometimes there's free gear for people to use if they don't have their own.
