Canadian Aids to Navigation System (CANS)
Various buoys, beacons and signs are known as "Aids to Navigation" or "Navigation Aids".
They are devices or systems external to the pleasure craft that help the operator of a pleasure craft to determine position and course. They also warn the operator of dangers or obstructions, or show the best or preferred route.
Be alert when you see a Navigation Aid. It's there for a reason. Examine your charts for hazards, and always be aware of your approximate location.
