Canadian Air and Space Museum, Aviation museum in Ontario, Canada

The Canadian Air and Space Museum is an aviation museum in Ontario displaying historical aircraft and space-related objects across multiple exhibition halls. The collection features both military and civilian planes that show the development of aviation in Canada.

The museum began as the Toronto Aerospace Museum and was relaunched as the Canadian Air and Space Museum on 20 February 2009. It occupied the oldest surviving aircraft factory building in Canada, the former de Havilland plant where the Beaver and Otter were built and Alouette I assembled. In September 2011 the landlord evicted all tenants; the collection went into storage, and in 2018 a move to Edenvale Airport was announced under the name Canadian Air and Space Conservancy.

The collection reflects how aviation shaped Canada and connected remote regions across the country. You can see how aircraft became essential to exploration, commerce, and everyday life in this vast nation.

The museum closed in September 2011, when the landlord evicted it and all other tenants of 65 Carl Hall Road; the site was later slated for a sports centre. Its collection went into forty-four 40-foot freight containers, then into warehouse space at Toronto Pearson until 2018. A reopening was announced for Edenvale Airport, about 100 km northwest of Toronto, in 2019.

The hangar that housed the museum is the oldest surviving aircraft factory building in Canada. There the de Havilland Beaver and Otter bush planes were built, and Alouette I, the first Canadian satellite, was assembled. The museum's Avro Arrow replica was moved to an Edenvale hangar in December 2018 after outdoor storage.
