The Ontario Science Centre's original Don Mills building closed in June 2024, and the institution has since moved to an interim presence at Harbourfront Centre on Queens Quay West in downtown Toronto, with a new permanent building planned at Ontario Place for around 2029. The interim site is reported to open to the public from summer 2026, so visitors should confirm current hours, ticket prices and exhibits on the centre's website before going.

The original Don Mills building closed in June 2024; an interim science centre has opened on the waterfront and a new building at Ontario Place is planned for 2029.

The Ontario Science Centre's original Don Mills building closed in June 2024, and the institution has since moved to an interim presence at Harbourfront Centre on Queens Quay West in downtown Toronto, with a new permanent building planned at Ontario Place for around 2029. The interim site is reported to open to the public from summer 2026, so visitors should confirm current hours, ticket prices and exhibits on the centre's website before going. The science centre has long been known for hands-on exhibits that let visitors experiment with physics, space, the human body, technology and the natural world, and its programming is aimed mostly at children, school groups and families. The waterfront setting places it among Harbourfront Centre's other cultural venues, with Lake Ontario views and ferry connections nearby. A typical visit is expected to take about two hours, though the length depends on the interim exhibits and any timed programs. Weekday mornings, when school groups arrive, can be lively but the site is often calmer than weekends in the afternoons. Because the interim site is new and details are changing, the information about specific exhibits, timed entry and accessibility is best confirmed directly. The location is reachable by the 509 Harbourfront and 510 Spadina streetcars to Queens Quay and Lower Spadina, or by taking Line 1 to Union Station and connecting to the 509. In Toronto, Ontario, the science centre pairs naturally with a walk along the waterfront and a visit to Harbourfront Centre's galleries and cafes.
