Air Defence Museum, Military aviation museum in La Baie, Canada.

The Air Defence Museum displays a large collection of military aircraft, flying technology, and defense systems from different periods of Canadian military history. The exhibits offer a detailed view of how aircraft, weapons, and protection systems developed and changed over the decades.

The museum was founded in 1997 and preserves the technological advances and strategies of Canadian air defense. Its collection documents the main developments in military aviation and changes in defense technology across multiple generations.

The museum is one of four aviation museums in Quebec, alongside Vintage Wings of Canada in Gatineau, the Montreal Aviation Museum in Sainte-Anne-de-Bellevue and the Quebec Aerospace Museum in Saint-Hubert. Its collection numbers more than 7,000 artefacts and a library of nearly 3,000 books on aviation.

Planning your visit beforehand is helpful since opening hours and guided tours can vary with the seasons. Comfortable shoes are good to wear, especially if you plan to explore the outdoor area with the aircraft.

The museum holds over 7,000 artefacts and a library of nearly 3,000 books on aviation, alongside the aircraft parked outside. Two CF-18 flight simulators let visitors try piloting a fighter jet themselves. The collection also includes a MiG 23, a Soviet-built type standing among the Canadian planes.
