The Montreal Port Authority manages the Boucherville Islands Archipelago, which is located at the downstream end of the port. The port authority is completing work to provide fish with spawning areas at several islands of the archipelago as part of an agreement with the Fisheries and Oceans Canada Fish Habitat Management Branch. The Coastal Fisheries Protection Act calls for the creation or improvement of habitant banks as compensation for the impact of development projects, such as the development of berths, on the environment.
