Many animals can be observed in various milieus and habitats along the Chambly Canal. In some sectors, you can spot species that tolerate man relatively well, such as skunks, raccoons, squirrels or marmots. In the more natural areas, different fauna can be seen, including American minks, turtles, amphibians and white-tailed deer. Some animals only stay here for part of the year, while others are more permanent residents. Wild land, parkland, wetlands, marshes, areas of cultivated lawn and riverside areas are all habitats found here.
However, the animals most often seen near the Chambly Canal are still avifauna and ichthyological fauna. The Richelieu River forms a corridor, making it an ideal migration route for many bird and fish species.
The Richelieu River serves as a migration route for many species because it runs north to south. Because the Chambly Canal runs alongside the river, this area offers many opportunities for birdwatching. Aquatic, land and arboreal birds can be spotted, depending on the time of year. An important migratory stop is located on the Richelieu River just near Saint-Jean-sur-Richelieu. Some years, in the fall, thousands of ducks and geese gather here.
The fish species found in the waters of the Chambly Canal are also found in the Richelieu River. However, not all the species found in the river are found in the canal because the waters are cloudy, with a weak current and a fair amount of aquatic plants. The fish species found in the canal are only those that thrive in this type of habitat.
The most frequently observed species are the yellow perch, pumpkinseed, carp, sucker, different types of redhorse, bass and many minnows.
The presence of many aquatic plants helps to attract certain species and encourage them to breed. Carps have often been seen spawning in the canal.
