Lighthouses of Canada: Southeastern Ontario

The nation of Canada was created by the British North America Act in 1867 with Ontario, Québec, New Brunswick, and Nova Scotia as the four original provinces. The area of Ontario was part of New France, the former French empire in North America, from tthe founding of Québec city in 1608 until France was forced to cede its Canadian territories to Britain at the end of the Seven Years War in 1763. Today Canada is a federation of ten provinces and three large federal territories in the far north of the country.

In 1798 the southern portions of modern Ontario were separated from Québec as Upper Canada, known after 1841 as Canada West and taking the name Ontario in 1867. Its territory was expanded northward several times and the province reached its present boundaries in 1912.

Ontario has a tremendous width east to west, including the entire Canadian side of the Great Lakes. Across this vast area there were once about 250 lighthouses. More than 130 remain, a large percentage of them active. This page lists the lighthouses in the southeastern part of the province including the Ottawa River and upper Saint Lawrence River. Lighthouses of Lake Ontario are listed on the Southern Ontario page.

Southeastern Ontario was originally divided into counties, but many of the counties have been combined in recent years to form regional governments.

Aids to navigation in Canada are maintained by the Canadian Coast Guard (CCG), an agency of Fisheries and Oceans Canada (DFO). In 2008 Parliament passed the Heritage Lighthouse Protection Act to designate and protect historic lighthouses.

ARLHS numbers are from the ARLHS World List of Lights. CCG numbers are from the Inland Waters volume of the List of Lights, Buoys, and Fog Signals of Fisheries and Oceans Canada. For lights of the St. Lawrence Seaway Admiralty numbers are from Volume H of the Admiralty List of Lights & Fog Signals and U.S. NGA numbers are from Publication 110. For lights near the international border USCG numbers are from volume 7 of the U.S. Coast Guard Light List.

Cole Shoal (Range Front) (Five Mile) (2)
2020 (station established 1856). Inactive since 1927; original light destroyed in 2018. 10 m (31 ft) square pyramidal wood tower with gallery, painted white. Lantern removed. Darlene Burns's photo is at right, Tianyi Gu has a 2021 photo, and Google has a satellite view. This was the only survivor of nine small lighthouses built in the Thousand Islands in 1856. The light served from 1916 to 1927 as the front light of the Cole Shoal Range, but it was deactivated in 1927 when the De Watteville range lights were placed in service. In 2002 the Ontario Heritage Foundation (now the Ontario Heritage Trust) spent $15,600 to restore the abandoned tower. It was destroyed by fire set by lightning on 23 July 2018. A committee, Five Mile Light Rebuild, quickly formed to rebuild it. The Trust declined to do so but was willing to lease or transfer the site. A campaign raised over $200,000 and a contract to rebuild the lighthouse was awarded in November 2019. The lighthouse was rebuilt between June and September 2020. Located on a rock in the river 8 km (5 mi) southwest of Brockville, off the end of Hudson Point Road. Accessible only by boat. Site open. Owner/site manager: Ontario Heritage Trust.
