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)<ref> Environment Canada. 2004.

The Code recommended, on a voluntary basis, that road authorities and municipalities applying more than 500 tonnes of road salt per develop salt management plans and implement best management practices for salt application, salt storage and snow disposal as described in the Transportation Association of Canada’s (TAC) Synthesis of Salt Management Best Practices (TAC, 2015)<ref>Transportation Association Canada (TAC). 2013.
