A comprehensive scientific assessment by Environment Canada and Health Canada determined that in sufficient concentrations, road salts containing inorganic chloride salts pose a risk to plants, animals and the aquatic environment (EC&HC, 2001) and are toxic substances as defined by the Canadian Environmental Protection Act, 1999.

Following the designation of chloride as a toxic substance, the Government of Canada established a Code of Practice for the Environmental Management of Road Salts under CEPA to help municipalities and other road authorities to better manage road salt use and reduce the adverse impacts of chloride, which maintaining road safety (Environment Canada, 2004).
