The Battle of Montgomery's Tavern was an engagement which took place on December 7, 1837 during the Upper Canada Rebellion. The abortive revolutionary insurrection, inspired by William Lyon Mackenzie, was crushed by British authorities and Canadian volunteer units near John Montgomery's tavern on Yonge Street at Eglinton, north of Toronto.
The site of Montgomery's Tavern was designated a National Historic Site in 1925[1][2] and a historical marker sits at the south-west corner of Yonge Street and Broadway Avenue.
