Three of the five lighthouses, including the one on Île de Bellechasse, were completed during 1861, and much progress was made on the remaining two. The following description of Bellechasse Island Lighthouse was given shortly before it was activated in 1862:
Bellechasse Island. — On the north-east end of this Island, at a point about 30 feet over the water-surface, a light tower has been erected, 29 ½ feet in height, with a sleeping apartment for the keeper attached to it. It consists of a square structure of wooden framework, with an octagonal lantern on it, 270 degrees of which are illuminated by means of 5 lamps, and a like number of parabolic reflectors – each 23 inches in diameter. The centre of the light will be about 64 feet over ordinary water surface.
A storm in October 1869 carried away a portion of the stairway that led down the rocky island to the river, and Mr. Cote and two men were landed on the island later that month to rebuild the missing portion of the stairs.
When Keeper Edward Thivierge complained in 1876 that the lighthouse leaked, he was told to have the clapboard siding nailed down, puttied, and painted. This must have been insufficient as by 1878, two sides of the tower had planks placed over its clapboards to make those sides watertight. Keeper Thivierge was pleased with the improvement and requested that the other two leaky sides receive the same treatment.
Keeper Thivierge didn’t have to worry about the leaky lighthouse much longer as he was superannuated in 1880 and replaced by Jean Baptiste Galibois, who was initially paid an annual salary of $320 and would look after the light until 1903.
Just prior to the opening of navigation in 1903, the fixed white light at Île de Bellechasse was changed to an occulting white light that was alternately visible for fifty-one seconds and eclipsed for three seconds. This change was brought about through the installation of a fourth-order lens that was illuminated by a lamp that burned petroleum vapour under an incandescent mantle.
Bellechasse Island Lighthouse was automated in 1964, and then replaced in 1969 by a skeletal tower. Today, a flashing yellow light is shown from a square, skeletal tower.
