The Ontario Science Centre Toronto closed its Don Mills building in June 2024, and the science centre now welcomes visitors at an interim home in Harbourfront Centre on the waterfront. The 1969 Raymond Moriyama hilltop building, a brutalist concrete landmark, is no longer open, so a visit now means the waterfront. Admission at Harbourfront Centre is $15 per visitor, tax included; check ontariosciencecentre.ca for current hours and what is on before you go.

Buying tickets
Tickets are sold through ontariosciencecentre.ca. Toronto CityPASS does not include the Science Centre; our Toronto CityPASS guide covers what it does include.
Combining with other family attractions
Edwards Gardens, the Aga Khan Museum and the Don Valley ravine trails were the natural pairings for the old Don Mills site. With the Ontario Science Centre Toronto now at Harbourfront Centre, plan the rest of the day around the waterfront instead; for green space elsewhere in the city, see our best parks in Toronto guide.
More Toronto days out with kids
The Science Centre is one of the anchors in our Toronto with kids guide. Pair the Ontario Science Centre Toronto with the rest of family trip planning: family attractions Toronto, playgrounds and splash pads Toronto, visiting with toddlers, Toronto CityPASS, family hotels Toronto, ROM, and Toronto Zoo.
The Ontario Science Centre Toronto carries on at Harbourfront Centre while the Don Mills building stays closed. Budget $15 a head with tax included, and check what is running on ontariosciencecentre.ca before you set out.
