Toronto Railway Museum

A moving walkway through a shark tunnel, and a pool where kids can reach in and touch the stingrays.

Hands-on play for ten and under, a planetarium and a workshop of tools to build with, in its temporary home by the lake.

The Stanley Cup itself, plus hockey games to play between the displays. You go in through the shopping concourse, not the old bank doors.

A slide and climbers with planes and ferries going by, so there's always something to point at.

Art-themed play zones next to the art gallery, so a museum morning can end with a climb.

Galleries plus a hands-on center where kids make things. The center keeps shorter hours than the rest, so check before you go.
