A hazard buoy is coloured white and has an orange diamond on two opposite sides and two orange horizontal bands, one above and one below the diamond symbols. Lights of different colours are used to assist recognition of the marks in the Canadian Aids to Navigation system. The following are the buoy colours used in the Canadian Buoyage System: The shape of an unlighted buoy indicates the position of the buoy with respect to the channel and thus the side on which the buoy should be passed: The use of topmarks as an additional means of daytime buoy identification is at present, restricted to lateral, cardinal, and isolated danger buoys in ice free conditions. The arrows always point to the black sections - in this case the upper and lower sections; East is at “Three o’clock” on the Compass - … G means a green light. Red and green lights are reserved for lateral marks and yellow for special marks. Topmarks are not used in Canada to the extent that they are used in other parts of the world because of the environmental conditions which Canadian aids to navigation must endure. A port hand buoy marks the port (left) side of a channel or the location of a danger which must be kept on the vessel’s port (left) side when proceeding in the upstream direction. Cardinal buoys indicate the location of the safest or deepest water by reference to the cardinal points of the compass. 2. A yellow light in which the total duration of light in a period is shorter than the total duration of darkness and is regularly repeated at a rate of 15 flashes per minute (1 flash every 4 seconds).. A yellow light in which a group of 5 flashes is regularly repeated 3 times per minute (every 20 seconds). The shapes of special buoys have no significance and a variety of shapes may be used in practice. As a way of remembering the light flash characters of the East, South and West Cardinal buoys, the number of flashes in each group for these lights is the same as the figure on the clock face in the corresponding compass direction (e.g. if it carries a light the light is yellow...flashing once every 4 seconds. Cardinal Marks. Buoying Depth:5~70mm Free Board:700mm Focal Plane Height:3031mm Net Weight:1748kg if it carries a topmark, the topmark is two black cones, one above the other, pointing downward.

If a cardinal buoy carries retroreflective material, such material is white. Notice the 'clockwise' resemblance of the light phase characteristics. All other aspects of the IALA Maritime Buoyage System are the same in both Regions “A” and “B”. A new danger may be marked by a RACON coded Morse “D”. 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. All types of buoys may be identified by a name in addition to a number or letter identification. For all buoys other than special buoys the colour of the retroreflective material is the same as that of the light which would be appropriate for each buoy.
