The first lighthouse, a pole light, was established at Grandique in 1884. After the opening of the St. Peter’s Canal, Lennox Passage saw an increase in marine traffic. For safety reasons, lighthouses were established along the route. The first keeper was Daniel Clough. Due to erosion at the Grandique spit of land, the pole light was moved in 1900 and in 1906 a proper lighthouse was built. Storm damage caused the Grandique Point lighthouse to be moved for a second time. In the winter of 2010, the lighthouse was moved to its present location.

The last lightkeeper at Grandique was Stanley Forgeron who took over in 1960. In 1961 Forgeron became a caretaker as the light was delisted.
