About Mission Channel Entrance Lighthouse

Established in 1917, this square, 7.5-meter tower guides vessels into the Mission River from Thunder Bay. The structure consists of a 1-story workroom topped by a square skeletal tower, painted white with red trim and a red gallery on the roof. Its green light flashes every two seconds, offering a 11.5-nautical-mile geographic range from a focal height of 13.5 meters. Located on an elbow of the breakwater at the river's south entrance, it is 3.5 kilometers from the nearest port. The Canadian Coast Guard maintains this operational lighthouse, which is only accessible by boat.

Why it matters: This lighthouse is indispensable for safe navigation into the Mission River, a key artery for local commerce and industry within Thunder Bay. Its precise placement on the breakwater directly mitigates risks for ships approaching the river entrance.
