""Transport Canada (Marine Safety) is tasked with managing a regulatory program that sets shipping procedures in order to reduce the risk of ship-mediated transfer of invasive species. Current ballast water regulations are being revised and Transport Canada has submitted a formal request to Fisheries and Oceans Canada (DFO) for science advice on the level of risk posed by the commercial shipping vector to Canadian waters. DFO's Centre of Expertise for Aquatic Risk Assessment (CEARA) has established guidelines for assessing biological risk of aquatic invasive species in Canada. The objective of the current advisory process is to assess the level of risk posed by ships transiting to, or from freshwater ports in the Great Lakes/St. Lawrence River (GLSLR) for the introduction of aquatic invasive species to Canadian waters and the level of risk posed by domestic shipping activities."--Document."
