During the War of 1812 the St. Lawrence was the life-line of Upper Canada along which virtually all military and civilian supplies were transported from Montréal to Kingston. Fear that the Americans might attempt to block the passage of materiel prompted the fortification of Bridge Island as a shelter for the supply batteaux and a base for British gunboats. A blockhouse was completed early in 1814 and a circular battery with an 18- pounder constructed. These defence works were maintained by a detachment of the 57th Regiment and artillerymen during 1814, but fell into disrepair soon after the war.

Description of Historic Place

Bridge Island / Chimney Island National Historic Site of Canada is located on Chimney Island in the St. Lawrence River, about 20 kilometres upriver from Brockville, Ontario. This island was the site of a fortified British garrison during the War of 1812, which protected the supply line to Lower Canada and provided a meeting point for British ships. In 1980, the Historic Sites and Monuments Board of Canada erected a plaque on the island to commemorate the site. Official recognition refers to the island as it was found at the time of designation.

Heritage Value

Bridge Island / Chimney Island was designated a national historic site of Canada in 1936 because: it was fortified and garrisoned in 1814 for the protection of the vital line of supply by water from Lower Canada and provided a rendezvous for boats engaged in that service during the War of 1812-14.

During the War of 1812, the St. Lawrence River was the lifeline of Upper Canada along which virtually all military and civilian supplies were transported from Montreal to Kingston. Fear that the Americans might attempt to block the passage of material prompted the fortification of Bridge Island / Chimney Island as a shelter for the “supply bateaux” and a base for British gunboats. A blockhouse was completed early in 1814 and a circular battery with an 18-pounder constructed. These defence works were maintained by a detachment of the 57th Regiment and artillerymen during 1814, but fell into disrepair soon after the war.
