Regional Information
The Canadian Coast Guard continuously strives to improve efficiencies in the provision of the Canadian aids to navigation system. In some instances, these efficiencies are achieved through the use and implementation of new products and technologies. These include but are not limited to changes in the use of plastic buoys rather than steel; and the use of LED lanterns.
Mariners are advised that every effort has been made by the Canadian Coast Guard to ensure that new equipment provides safe and reliable aids to navigation systems. If there are any concerns please contact the Superintendent, Aids to Navigation in your region.
NEWFOUNDLAND AND LABRADOR REGION
The lights on the South Coast of Newfoundland from Cape St. Francis on the Avalon Peninsula to Cape Anguille on the shore of Cabot Strait and certain lights in Notre Dame Bay, Bonavista Bay, Trinity Bay, Conception Bay and Bay of Islands are exhibited all year. All other lights under the control of the Canadian Coast Guard are maintained in operation whenever navigation in the vicinity is open. Lights used solely as harbour lights are not exhibited when the harbour is closed, although general navigation may remain open.
Lights which are primarily for the benefit of fishermen are maintained only during the fishing season. In any case where there is reasonable doubt whether the light is required it is kept in operation. During the winter, some lighted buoys are replaced with winter spars so that it should not be assumed that there are no aids present even though the lights in a given area have been extinguished for the season. The details of all changes in aids to navigation will be described in Navigational Warnings.
Navigational buoys at St. John's, are listed as being in operation year round. While every effort is made to adhere to this period, mariners are cautioned that ice movement may result in the buoys being lifted and in some cases replaced by winter spars between January and April.
The Newfoundland Region now has a fully lighted aids to navigation system. However, due to potential ice conditions on the East Coast, lights on year round floating aids to navigation in these waters may be temporarily removed until ice conditions subside. Mariners are advised to use extreme caution when navigating the East Coast waters during this season.
Cautions in the Use of Aids to Navigation
1 Mariners are cautioned not to rely solely on buoys for navigation purposes. Navigation should be by bearings or angles from fixed aids on shore or other charted landmarks and by sounding or through the use of satellite or radio-navigation systems, whenever possible.
2 Most aids to navigation are not under continuous observation and mariners should be aware that failures and displacements do occur. The Canadian Coast Guard does not guarantee that all aids to navigation will operate as advertised and in the positions advertised at all times. Mariners observing aids to navigation out of operation, out of position, damaged or missing are responsible for reporting such problems to the nearest Canadian Coast Guard Marine Communication and Traffic Services Centre on VHF Ch. 16 immediately or to the closest Canadian Coast Guard office.
3 Aids to navigation are subject to damage, failure and dislocation. This may be caused by ice, storms, vessel strikes and power failures. Ice and storm damage may be widespread and require considerable time to repair. Isolated damage may exist for a long time without being discovered and reported. Floating aids and pier lights in or near the water which are exposed to particularly rigorous strain during ice movement are at the greatest risk of damage.
4 Mariners are cautioned that aids to navigation may fail to exhibit their advertised characteristics. Lights may be extinguished or aural signals may not function due to ice, collisions, mechanical failure and, in the case of bell and whistle buoys, calm water. The shape of an aid to navigation may be altered by ice formation or damage. The colour of an aid to navigation may be altered by freezing spray, marine growth or fouling by birds.
5 The buoy positions shown on nautical charts should be considered as approximate positions. There are a number of limiting factors in accurately positioning buoys and their anchors. These factors include prevailing atmospheric and sea conditions, tidal and current conditions, seabed conditions and the fact that buoys are moored to anchors by varying lengths of chain and may drift about their charted positions within the scope of their moorings.
6 Since moving ice is liable to move buoys from their advertised positions, mariners should proceed with extreme caution under these circumstances.
7 Mariners are reminded that because of differences in horizontal datum (i.e. NAD 27, NAD 83), grids of charts of an area may vary from one chart to another. When plotting the positions of aids to navigation by the latitude and longitude method, the results should be checked against other available information.
8 In some instances it is necessary to establish a buoy in close proximity to or on a navigational hazard (e.g. shoal, reef or ledge, etc.). In these instances the buoy symbol may be off-set slightly on the chart in the direction of the preferred navigable water so that the existing hazard depicted on the chart will not be overprinted by the buoy symbol. Such off-sets will be indicated on the chart by means of an arrow.
9 Mariners are cautioned not to navigate too closely to a buoy and risk collision with it, its mooring or with the underwater obstruction which it marks.
10 Many lights are equipped with sun switches. These lights, both on shore and on most buoys, are unlit between sunrise and sunset. Mariners unable to see these lights during the daylight hours should not assume that the equipment is malfunctioning.
11 Many light stations which exhibit a main light 24 hours per day are equipped with an emergency light which is brought into service automatically in the event of failure. These emergency lights are white, have a standard character of group flashing (6)15s and operate throughout the hours of darkness. Emergency lights are normally visible at 5 nautical miles on a dark night with a clear atmosphere. The List of Lights, Buoys and Fog Signals publications identify which aids to navigation are equipped with emergency lights.
12 Atmospheric conditions can have a considerable effect on light transmission and the visibility of lights. For example:
- The distance to a light cannot be reliably estimated from its apparent brightness.
- It is difficult to distinguish between a white light and a yellow or blue light seen alone at night, except at a short distance.
- Under some atmospheric conditions white and yellow lights take on a reddish hue.
- Alternating lights with phases of different luminous intensity may change their apparent characteristics at different distances because some phases may not be visible.
- When observed from similar distances, lower intensity lights are more easily obscured by conditions of low visibility than more powerful lights. Coloured lights are often of lower intensity than white lights and are more quickly lost under unfavourable circumstances.
- Ice, frost or moisture may form on the windows of lantern during cold weather and more particularly this may reduce their visibility and could cause coloured lights to appear white.
- A light exhibiting a very short flash may not be visible at as great a range as a light exhibiting a longer flash.
13 The mariner should not rely solely on colour when using a sector light, but should verify the vessel's line of position by taking a bearing on the light. On either side of the line of demarcation, between white and red, and also between white and green, there is always a small arc of uncertain colour.
14 When the arc of visibility of a light is cut off by sloping land, the bearing at which it disappears or appears will vary with the observer's distance and height of eye.
15 The sighting of a light may be adversely affected by a strongly illuminated background.
16 In view of the varying distances at which a fog signal can be heard at sea, and the frequent occurrence of fog near, but not observable from, a fog signal, mariners are cautioned that:
- When approaching land in fog, they should not rely implicitly upon these fog signals, but should always take soundings, which in nearly all cases will give sufficient warning of danger.
- Distance from a fog signal should not be judged by the power of the sound. Under certain atmospheric conditions the sound may be lost at a very short distance from the signal. These conditions may vary within a very short period of time. Mariners should not assume that a fog signal is not in operation because they do not hear it, even when in close proximity.
17 Visual aids to navigation provided by the Canadian Coast Guard are for the purpose of assisting marine navigation. Hunters, snowmobilers and ice fishers are cautioned that aids to navigation installed for marine navigation purposes cannot be relied upon after the close of the marine navigation season. Such aids may stop operating without warning and will not be re-commissioned by the Canadian Coast Guard until the next opening of marine navigation season.
ABBREVIATIONS AND EXPLANATIONS
POSITION AND DESCRIPTION OF AIDS.
The positions of all aids listed in this volume refer to the largest scale Canadian Hydrographic Service paper chart.
Information on position, characteristic, colour, visible range, bearings, and arcs of visibility is intended for practical use in navigation. It should not be used as a basis for surveys or other work requiring a high order of precision.
The geographical positions of the lights are approximate. The bearings are true and are given from seaward, except for fog signals, in degrees from 000° (North) to 359°, measured clockwise (unless otherwise indicated).
Emergency changes are covered by Navigational Warnings and the operation of the aid restored to normal as soon as possible.
PRIVATE AIDS
Aids which are identified by the words "Private aid" are not owned by the federal government, a provincial government or a government agency. The Canadian Coast Guard considers any aid owned by a municipal government to be private. Since their quality of operation may not be maintained to Canadian Coast Guard standards, the user should ensure that the service provided by these aids is adequate for their needs in regard to navigating the ship safely.
LIGHT CHARACTERISTICS.
A light's characteristic is composed of:
- RHYTHM the sequence of intervals of light and darkness;
- COLOUR the colour exhibited by the light;
- PERIOD the time taken to complete one rhythm cycle (not applicable to fixed lights) e.g. a South Cardinal buoy light may display a characteristic of (Q(6) + LFl) W 15s - its rhythm, (Q(6) + LFl), is a group of 6 quick flashes followed by a single long flash its colour, W, is white the period of time this cycle is repeated 4 times per minute (every 15 seconds).
DAYMARKS.
The Description column of the List of Lights describes the shape of daymarks for all lights. Should no shape of daymark be mentioned for range lights, it can be assumed that the daymarks are trapezoidal.
RADAR REFLECTORS.
All lighted buoys reflect radar and thus radar reflectors on buoys are not mentioned in the "Remarks" column. Some shore lights have added radar reflectors to enhance their radar reflection and these are noted in the "Remarks" column.
THE CANADIAN AIDS TO NAVIGATION SYSTEM .
The Canadian Aids to Navigation System is comprised of a mix of visual, aural and electronic aids to navigation. When used individually or in combination, they help the mariner to determine position and course, warn of dangers or obstructions and indicate the best or preferred route.
It is a combined lateral - cardinal system and conforms to the IALA (International Association of Lighthouse Authorities) Maritime Buoyage System, Region "B". Details of the Canadian aids to navigation system can be found in the publication "The Canadian Aids to Navigation System", available on the Canadian Coast Guard website : https://www.ccg-gcc.gc.ca/publications/maritime-security-surete-maritime/aids-aides-navigation/page01-eng.html.
RADAR BEACONS (RACONS).
Radar beacons (Racons) may be established at lighthouses, on buoys or at other specific charted locations ashore or afloat, to enhance identification and detection range of these features by radar.
Some Racons operate only in the X band 9320-9500 MHz, whilst others are dual band X/S, "X" band plus "S" band of 2920-3100 MHz. It should also be noted that the slow sweep (SS) type of Racon will give a response every 72-120 seconds, whilst the frequency agile Racon (FAR) will respond more frequently.
The Racon signal appears on the radar display as a line commencing at the approximate range of the Racon and extending outwards along its line of bearing from the ship toward the limit of the display. The signal displayed may be a solid line or it may be broken into a code consisting of a series of dots and dashes as shown in relevant publications.
Radiobeacons and Radar beacons (Racons) shown in this volume are indicated at the nearest light. Complete information may be obtained from the appropriate volume of the publication "Radio Aids to Marine Navigation" available on the Canadian Coast Guard website : https://www.cgc.gc.ca/publications/mcts-sctm/ramn-arnm/indexeng.html.

NOMINAL RANGE.
The nominal range of a light used as an aid to marine navigation is its luminous range in a homogeneous atmosphere in which the meteorological visibility is 10 nautical miles.
INTERNATIONAL NUMBERS.
An international reference number is shown in italics under the regular List of Lights number against certain lights considered to be of international significance. The purpose of these numbers is to provide an easy method of identifying the lights when reporting by wireless, defects or changes in their advertised characteristics.
When reporting on lights, which do not have an international reference number, mariners are requested to identify them by List of Lights number and the name of the volume.

Example: An observer whose eye is 12 metres above the water can see a light having an elevation of 40 metres above the water at a distance: 7.2 + 13.1 = 20.3 nautical miles. |
1 NAUTICAL MILE = 1852 metres Note: The following conversion factors may also be of assistance: a) multiply feet by 0.3048 to obtain metres; b) divide metres by 0.3048 to obtain feet. |
NOMINAL RANGE DIAGRAM
The light list in column 7 gives the nominal range of each lightstation optic where there is sufficient light to be seen 2 nautical miles or more when the meteorological visibility is 10 nautical miles.
When the mariner obtains the meteorological visibility from the weather report he can find the distance the light can be seem at night from the nominal range diagram.
Example: The light list gives the nominal range 16 nautical miles. The weather report gives the meteorological visibility 2 nautical miles. The point on the bottom of the diagram marked 16 is followed upwards until it intersects the curve marked 2 nautical miles. Follow that height horizontally to the left margin to find that the visibility of the light is 5 nautical miles.
Caution: The nominal range diagram is correct when the meteorological visibility is the same in the whole of the distance between the ship and the lighthouse. Conditions occur when this may not be true.
NOMOGRAM
By using the above Nomogram a geographical range can be determined by placing a straightedge against the height of the respective light and the height of the observer above water level.
