Imperial Towers

The Imperial Towers of Ontario were six of the earliest lighthouses built on Lake Huron and Georgian Bay,^[1] all constructed primarily of stone, by the Province of Canada. The origin of the designation Imperial is not certain, but some historians speculate that because the towers were public construction built under the colonial administration while Canada was a self-governing colony of Britain, the name would assure at least some funding from the British Empire's Board of Trade.^[2]

All were built at a time when commercial shipping traffic was increasing on the Great Lakes between Canada and the U.S. because of new trade agreements and the opening of the Sault Ste. Marie Canal locks in 1855. The settlement of the Bruce Peninsula was already well underway at the time, also making the lighthouses timely as navigational aids for the boats and ships. All are currently operating as automated lights.^[3][4]
