Waterways Management

The Canadian Coast Guard’s (CCG’s) Waterways Management program helps to ensure safe and efficient navigation, supports protection of the marine environment, and facilitates marine trade and commerce.

Safe, efficient and environmentally-sound use of our waterways brings economic benefits to the marine shipping industry as well as economic and social benefits to the public.

Program activities include:

  • helping to ensure safe, efficient and environmentally-responsible design, maintenance and use of ship channels and marine structures within those channels;
  • providing channel safety information to users (such as channel bottom conditions and water level forecasts); and
  • representing the interests of commercial navigation in the International Joint Commission’s process for control of water levels and flows in the Lake Ontario–St. Lawrence River system.
