Explanatory Notes – Notices to Mariners (NOTMAR)

Geographical positions refer directly to the graduations of the largest scale Canadian Hydrographic Service chart (unless otherwise indicated).

Bearings refer to the true compass and are measured clockwise from 000° (North) clockwise to 359°; those relating to lights are from seaward.

Visibility of lights is that in clear weather.

Depths - The units used for soundings (metres, fathoms or feet) are stated in the title of each chart.

Elevations are normally given above Higher High Water, Large Tide (unless otherwise indicated).

Distances may be calculated as follows:

1 nautical mile = 1,852 metres (6,076.1 feet)
1 statute mile = 1,609.3 metres (5,280 feet)
1 metre = 3.28 feet

Temporary and Preliminary Notices to Mariners – Section 1A of Notices to Mariners

These notices are indicated by a (T) or a (P), respectively. Please note that nautical charts are not amended by the Canadian Hydrographic Service for temporary (T) and preliminary (P) notices. It is recommended that mariners chart these corrections in pencil. For the list of charts affected by (T) & (P) notices, please refer to the current Notices to Mariners - Monthly Summary of Temporary and Preliminary Notices publication.

Chart Corrections – Section 2 of Notices to Mariners

Corrections to nautical charts will be listed in numerical order by chart number. Each chart correction listed applies only to that particular chart. Related charts, if any, will have their own specific correction listed separately.

Users should also refer to CHS Chart 1: Symbols, Abbreviations and Terms for additional information pertaining to the correction of charts.

The illustration below describes the elements that will comprise a typical Section 2 chart correction:

elements of section 2

The last correction number is identified with the LNM/D or Last Notice to Mariners Number / Date.

Mariners are advised that only the most critical changes that directly affect safety to navigation are issued in “Section 2 – Chart Corrections.” This limitation is required to ensure that charts remain as clear and easy to read as possible. As a result, mariners may see minor discrepancies of a non-critical nature between information in official publications. For example, a small change in the nominal range or focal height of a light may not result in the production of a chart correction in Notices to Mariners, but may result in a correction in the List of Lights, Buoys and Fog Signals publication.

Note: In the case of a discrepancy between information provided on CHS charts relating to aids to navigation, and the List of Lights, Buoys and Fog Signals publication, the latter shall be deemed as containing the most up-to-date information.

Navigational Warnings / Notices to Shipping

The Canadian Coast Guard (CCG) is implementing a number of changes to the aids to navigation system in Canada.

These changes are advertised as Navigational Warnings, formerly called Notices to Shipping^{Footnote 1}, that are broadcast by the CCG, and are then followed up with Notices to Mariners, then charts are updated by hand correction, reprints or new editions.

Mariners are advised that all relevant Navigational Warnings (NAVWARN) should be kept until superseded by Notices to Mariners or through revised charts issued by the Canadian Hydrographic Service (CHS).

NAVWARN are accessible on the applicable regional page on the CCG Navigational Warnings.

CHS is reviewing the impact of these changes with CCG and together are preparing an action plan on the issuing of chart revisions.

For further information, contact your regional NAVWARN Issuing Desk.

(Recurrent publication of notice *505/23, originally published in the Notices to Mariners – Monthly Western Edition 05/2023 publication.)

Mariners are advised that CHS has adopted the harmonized World Magnetic Model (WMM), as found on the NCEI/NOAA website. Old compass rose declination information on CHS navigational products can be updated using the Magnetic Declination Estimated Value website. While the differences in the model declinations are small each year, they can become more significant over a large period of time.

(Recurrent publication of notice *1207/23, originally published in the Notices to Mariners – Monthly Western Edition 12/2023 publication.)

The records of the Canadian Hydrographic Service could contain geographical names that may be considered inappropriate, offensive and derogatory. Geographical naming authorities are in the process of addressing many offensive place names, the review process is underway. For more information, about inappropriate geographical names, please see the following announcement.

*208/24West Coast Haida Gwaii – Voluntary Protection Zone for Shipping

(Recurrent publication of notice *208/24, originally published in the Notices to Mariners – Monthly Western Edition 02/2024 publication.)

Reference: Notice *1105/21 is cancelled.

Voluntary Protection Zone for Shipping, western shore of Haida Gwaii
(formerly Queen Charlotte Islands)

Haida Gwaii’s remote location, rugged coastline, variable sea and weather conditions, and rich ecological and cultural heritage make it vulnerable to the potential for pollution from shipping breakdowns and accidents. Increasing the distance vessels travel offshore can increase the amount of time available to address propulsion, steering or other issues, and the likelihood of a towing vessel being able to respond to a vessel in distress or drifting. This in turn reduces the risk of grounding and oil spills.

A Voluntary Protection Zone for Shipping on the western shore of Haida Gwaii is currently in effect. In the Voluntary Protection Zone, commercial vessels of 500 gross tonnage or greater are requested to observe a minimum distance of 50 nautical miles from the western shore of Haida Gwaii with the following exemptions:

Exemptions from requested 50 nm distance:

•Cruise vessels, which are asked to observe a minimum 12 nm distance from shore;
•Vessels transiting from Alaska to British Columbia or Washington State, or vice versa, through the Voluntary Protection Zone are asked to observe a distance of at least 25 nm from shore
•No minimum distance is requested for tugs and barges (including pushing and towing alongside) or vessels engaged in commercial fishing.

•Vessels to which this bulletin applies are not required to observe requested minimum distances if doing so may compromise navigational, vessel, passenger or cargo safety.

The Voluntary Protection Zone for Shipping coordinates are:

54⁰ 15.436' N	133⁰ 04.788' W
54⁰ 17.572' N	134⁰ 02.484' W
54⁰ 13.614' N	134⁰ 19.427' W

51⁰ 56.158' N	131⁰ 01.830' W

Vessels are requested to adhere to these distances on a voluntary basis and only when it does not jeopardize the safety of navigation, the vessel, the persons onboard, and the cargo.

*1105/24Transport Canada – British Columbia North Coast Waterway Management Guidelines

(Recurrent publication of notice *1105/24, originally published in the Notices to Mariners – Monthly Western Edition 11/2024 publication.)

Reference: Notice *1004/23 is cancelled.

The North Coast Waterway Management Guidelines are voluntary guidelines that aim to improve safety on the water by reducing conflicts between First Nations’ marine use activities, such as fishing and shoreline harvesting, and commercial vessels on the shipping route between Kitimat and Browning Entrance. The guidelines came into effect on September 1, 2022, and will be reviewed from time to time.

The guidelines apply to all vessels navigating on the route between Kitimat and Browning Entrance, on the north coast of British Columbia. This area includes:

•Douglas Channel	•Otter Channel
•Wright Sound	•Nepean Sound, and
•Lewis Passage	•Principe Channel

The complete guidelines document is available at British Columbia North Coast Waterway Management Guidelines.
Nothing in these guidelines replaces or changes how we apply any Canadian or international laws or regulations, including the Collision Regulations. Furthermore, nothing in these guidelines prevents or limits the master or pilot of a ship from making any decisions to protect the vessel, the crew, or the marine environment.

The guidelines include information for:

•all vessels that covers:

- inshore safety zones
- routing measures
- speed reductions
- guidelines for meeting and passing

- a special operating area in Wright Sound, and
- guidelines in case of a mechanical or electrical breakdown

•large commercial ships, including bulk carriers, general cargo vessels, liquid bulk vessels, and passenger vessels
•tugs and barges, and

•vessels operating in First Nations Areas of Concern where you must pay special attention to make sure local community users can transit and use the area safely.

*506/25Anguniaqvia Niqiqyuam Marine Protected Areas (ANMPA), Tarium Niryutait Marine Protected Areas (TNMPA) and Beluga and Bowhead Whale Protection: Voluntary Avoidance and Slowdown Areas

(Recurrent publication of notice *506/25, originally published in the Notices to Mariners – Monthly Western Edition 05/2025 publication.)

The two established Marine Protected Areas (MPAs) in Canada’s Western Arctic are located within the Inuvialuit Settlement Region, as such all activities must comply with the Inuvialuit Final Agreement. Protection and preservation of Arctic wildlife, the environment and biological productivity is one of the principles of the Inuvialuit Final Agreement and it is this principle that led the Inuvialuit Regional Corporation and the Inuvialuit Game Council to initiate establishment of the Western Arctic MPAs. The waters in and near the MPAs, and the offshore marine habitats of the Beaufort Sea and Amundsen Gulf, are important summer foraging habitats and travel routes used seasonally (May-October) by the Eastern Beaufort Sea beluga stock, and the Bering-Chukchi-Beaufort bowhead population.

REGULATORY PROTECTION MEASURES

All whale species are protected under the Marine Mammal Regulations, pursuant to the Fisheries Act requiring immediate reporting of accidental contact between a vehicle or fishing gear and a marine mammal to the Minister. Within the boundaries of the MPAs, a general prohibition is set out in the Regulations, pursuant to the Oceans Act prohibiting activities that disturb, damage, destroy or remove any living marine organism from the areas. Any accident, including those with a marine mammal within the TNMPA must be reported within two hours after its occurrence, to the Canadian Coast Guard. For marine accidents such as collisions that occur within the ANMPA or outside the MPAs or for any situation involving a marine mammal that is dead or in trouble, report to the Fisheries and Oceans Canada, Inuvik office at (867) 777-7500.
For more information on the ANMPA and TNMPA, including local contacts and species-specific minimum distances, see Section A2 - Notices 5 and 5A.3 of the Notices to Mariners Annual Edition.

VOLUNTARY PROTECTION MEASURES

Voluntary measures are in effect from June 1^st to October 31^st. See map above.

These measures apply to merchant vessels, cruise ships, small vessels and adventure craft within the boundaries of the MPAs and the additional identified areas to prevent collisions with whales and to mitigate the underwater noise generated by the vessels. These measures should only be taken when they will not jeopardize navigational safety.
Avoid (red area): To reduce the risk of underwater noise disturbance and collisions with whales within the MPAs, vessels should avoid transiting through the MPAs if possible. If passage through this area is necessary, vessels should slow down to a speed not exceeding 10 knots over the ground and post additional lookouts such as a marine mammal observer in order to increase the chances of seeing the whales and thus taking necessary measures to avoid them. If bypassing the whales is not possible, slow down and wait for the animals to move away to a distance greater than 400 metres (0.215 nautical miles) before resuming original speed not exceeding 10 knots over the ground. It is more difficult to see the animals in rain, fog, or in rough sea states, therefore increased caution is recommended.
Slow down to 10 knots over the ground or less (yellow stippled areas): To reduce the risk of underwater noise disturbance and collisions with whales within these areas, it is recommended that vessels should slow down to a speed not exceeding 10 knots over the ground, navigate within the marked community supply channels and post additional lookouts.
These voluntary measures are secondary to rights under the Inuvialuit Final Agreement.
