Road salts overview
Road Salts are used in Canada as de-icing and anti-icing chemicals for winter road maintenance, with some use as summer dust suppressants.
A comprehensive five-year scientific assessment by Environment Canada determined that in sufficient concentrations, road salts pose a risk to plants, animals and the aquatic environment. A Risk Management Strategy for Road Salts was subsequently developed to outline the measures that Environment Canada proposes in order to manage the risks associated with road salts.
Under the Canadian Environmental Protection Act, 1999, the Government of Canada published a Code of Practice for the Environmental Management of Road Salts on April 3, 2004. The Code is designed to help municipalities and other road authorities better manage their use of road salts in a way that reduces their impacts on the environment while maintaining road safety.
The Code of Practice recommends that road authorities prepare salt management plans that identify actions they will take to improve their practices in salt storage, general use on roads and snow disposal. Environment Canada has completed a Five-year Review of Progress that indicates the Code has been effective in increasing the use of best practices for managing road salts in Canada. The Code and Review were developed in consultation with a Multistakeholder Working Group for Road Salts.
The Review identified several actions that could be considered for the continued improvement in road salt management. One of these actions is to set national targets for the implementation of best practices against which performance of the road organizations and the success of the Code can be evaluated. Proposed Performance Indicators and National Targets were published for a 60 days public consultation period. A summary of comments has been published on Environment Canada’s CEPA Environmental Registry website. Final Performance Indicators and National Targets were issued on December 23rd, 2014.
The Government of Canada is not banning the use of road salts nor proposing any measures that would compromise or reduce road safety.
