Bonsecours Market at 350 rue Saint-Paul in Old Montreal, is a two-story domed public market. For more than 100 years, it was the main public market in the Montreal area. It also briefly accommodated the Parliament of United Canada for one session in 1849.
Named for the adjacent Notre-Dame-de-Bon-Secours Chapel, it opened in 1847. During 1849 the building was used for the Legislative Assembly of the Province of Canada. The market's design was influenced by Dublin's Customs House.
