Musée Stewart Montréal

Inside the old Arsenal British garrison (where troops were stationed in the 19th century), this beautifully renovated museum displays relics from Canada’s past in its permanent exhibition, History and Memory. In summer there are military parades outside by actors in 18th-century uniforms; check the website for details. It’s a 1km (about 15-minute) walk from Jean-Drapeau metro station.
