Île Sainte-Thérèse Lower Range Front Lighthouse

Structure: The Île Sainte-Thérèse Lower Range Front Lighthouse plays a vital role in guiding mariners through the waterways surrounding Île Sainte-Thérèse in Canada. As a front range light, its primary purpose is to work in conjunction with a corresponding rear range light, providing a precise alignment for vessels navigating a specific channel. This active aid to navigation ensures safe passage, particularly in areas where currents or shallow waters might pose a hazard to shipping. While specific historical events or detailed architectural descriptions are not provided, its continued operation underscores its ongoing importance to both local and commercial shipping traffic. The light's focal plane is positioned at 11 meters above the water, offering a clear and reliable guide to those traversing these Canadian waters, helping them maintain the correct course through designated navigation lanes.
