Banc de Carleton is a sandspit near the town of Carleton, in Chaleur Bay, Québec. The Carleton sandbar is approximately 2 km long and has a north-south orientation. It begins from the main land toward, and almost reaches, the end of another spit the Larocque sandbar. This sandbar begins at Pointe de Bourque and stretches in an east-west direction. Only 200 metres separate the two sandbars. It is not included in the IBA because it is mainly used as a provincial campground.. The average temperature in this region is 3.7°C.
Banc de Carleton supports significant numbers of breeding Common Tern. Between 1979 and 1995, the colony was surveyed five times, with an average of 612 pairs, or about 1.2% of the estimated North American population, present at this site. The following numbers of birds were recorded: 390 pairs in 1979, 841 pairs in 1989, 880 pairs in 1991, 630 pairs in 1993, and 320 pairs in 1995.
