Repentigny is an off-island suburb of Montreal situated north of the city between St. Lawrence River and the lower portion of L'Assomption River.

A pair of wooden towers were first built at Repentigny in 1843 to exhibit range lights for guiding mariners along St. Lawrence River. The front tower stood fourteen feet tall and the rear tower twenty-six feet tall according to early Light Lists. Early photographs show the front light was exhibited from a square structure with vertical sides that was topped by an octagonal lantern room. The rear lighthouse consisted of an octagonal tower surmounted by an octagonal lantern room.

J. Baptiste LaChappelle was in charge of the front range light from 1861 through 1912. During this period, members of the Rivet family cared for the rear light. Land for the front lighthouse was acquired from Joseph Grenier, while C. Rivet sold the land needed for the rear lighthouse.

In 1913, the range lights were moved to new sites to shift the alignment of the range somewhat to the east to mark the axis of the channel dredged west of Ile Deslauriers. The cost of the change in the lights and acquiring the new sites was $1,101.59. While the front light was being moved 820 feet to a location near the public road, a temporary fixed white light was shown from an anchor lens lantern hoisted on a mast. At this time, the structure for displaying the rear light was changed to a skeleton tower, square in plan, with sloping sides and surmounted by an enclosed watchroom and square lantern room. The height of the new rear tower was forty-five feet from its base to the top of the ventilator on the lantern room. The front structure remained a square building topped by an octagonal lantern room.

In 1927, a new lighthouse in the form of a square, wooden, pyramidal tower surmounted by a square lantern room was built to display the front range light.

There are no longer range lights at Repentigny.
