Some are cautionary buoys to mark firing range or seaplane bases, while others gather weather information, locate prohibited areas or mark designated mooring areas. Please see the Canadian Aids to Navigation System map for more details. Many special buoys are privately owned and, as such, must conform to the Private Buoy Regulations. when greater perception requirements demand or to improve the light’s availability in severe waves conditions. A white light in which a flash of 2 seconds duration is repeated at a rate of 6 flashes per minute (1 long flash every 10 seconds). Section 2 of Radio Aids to Navigation provides a complete list of RACONS with information such as name and location, range, arc and identifier. Cardinal marks warn of hazards to be avoided such as shallows or rocks. Swimming and diving buoys, which are white in colour, will use yellow retroreflective material. Lights of different colours are used to assist recognition of the marks in the Canadian Aids to Navigation system. An east cardinal buoy is located so that the safest water exists to the east of it.

In cases where special buoys display retroreflective material, such material will be yellow. A Cardinal Mark is named after the quadrant in which it is placed. The use of such buoys is generally restricted to coastal waters where there is sufficient buoy motion to activate the sound device and where there is a requirement for an audio signal to enable location of the buoy under low visibility conditions.
