Canada's prairie provinces of Saskatchewan and Alberta have no officially maintained lighthouses. They do have many lakes and reservoirs and a small number of privately built lighthouses. Even though they are unofficial, we list these lighthouses if they stand beside navigable water, have some plausible navigational value, and are active during the local boating season.

Saskatchewan Lighthouse
** Cochin

1989. Active (privately maintained); focal plane about 48 m (155 ft); flashing white light. 11.5 m (38 ft) hexagonal wood tower with lantern and gallery. D.J. King's photo is at right, Lighthouse Explorer has a photo by Amy Chang, Michelle Paul has a 2012 photo, Elisabeth Poscher has a 2011 photo, and Bing has a satellite view. Built as a tourist attraction, the lighthouse overlooks both Cochin and Jackfish Lakes from the narrow isthmus between the two. It stands on Pirot Hill, a site donated by Don and Hilda Pirot. Located on SK 4 just north of Cochin, Saskatchewan. Site open, tower apparently open in season (details are needed). Owner/site manager: Village of Cochin.

Alberta Lighthouse
#Sylvan Lake

1988. Demolished in 2012. Approx. 20 m (66 ft) octagonal tower with lantern and gallery. Lighthouse painted white; the gallery and lantern roof were red. A closeup photo is available, Wikimedia has Kor Nielsen's closeup photo, Joanna Reyburn has a distant view, and Google has a satellite view. In August 2012, it was announced that the privately-owned lighthouse would be removed to make way for new development, and it was toppled on 18 October 2012. The Sylvan Lake Rotary Club is coordinating efforts to build a replacement lighthouse. The lighthouse was located at the Sylvan Lake Marina, at the southeast end of Sylvan Lake, about 20 km (13 mi) west of Red Deer, Alberta.
