2026 Traffic management measures to protect North Atlantic right whales in Canada

Transport Canada (TC) – April 22, 2026 – This notice to fish harvesters is issued in accordance with the 2026 traffic management measures to protect North Atlantic right whales (NARW) in Canada.

Due to changing migration patterns of North Atlantic right whales and their increased presence in the Gulf of St. Lawrence, the Government of Canada has set seasonal speed restrictions in specific zones. These speed restrictions zones are defined as:

See the map below for details.

Note:

Vessels must follow Navigational Warnings outlining the speed restrictions. The Interim Order for the Protection of North Atlantic Right Whales in the Gulf of St. Lawrence, 2026, enables the issuance of Navigational Warnings (NAVWARNs) imposing speed restrictions and navigation restrictions.

Speed restriction zones are described in monthly Notices to Mariners (NOTMARs), which are published by the Canadian Coast Guard. The status of these zones is broadcasted through NAVWARNs, which are published by the Coast Guard's Marine Communications and Traffic Services Centres.

Speed restriction zones and measures

The speed restriction zones will be effective from April 22nd, 2026, while the restricted area will be implemented based on whale presence.

Please check the latest NAVWARN for all speed restrictions currently in effect.

Speed restriction measures for 2026

The restrictions are in effect from April 22 to November 15, 2026.

Non-application

The measures described in this bulletin do not apply to:

  1. a vessel in distress or providing assistance to a person or a vessel in distress;
  2. a government vessel being used
    1. for law enforcement activities;
    2. for search and rescue operations; or
    3. to ensure the competency of the crew or the operational readiness of the vessel or crew with respect to such activities or operations.

Static zones

In the static zones, all vessels above 13.0 m in length overall (LOA) must proceed at a speed of not more than 10.0 knots over the ground.

Exclusions

Air cushion vessels operated by or on behalf of the Government of Canada that are engaged in ice-clearing activities from April to June in and around Chaleur Bay are exempted when in operation.

36.57 m (20-fathom) shallow water protocol exclusion

Vessels engaged in any commercial fishing activity may proceed at a safe operational speed in waters not more than 36.57 m (20 fathom) deep within the static zones.

If a NAVWARN states that at least one North Atlantic right whale has been detected in waters within a static zone or its buffer zone that are not more than 36.57m deep, the speed limit of 10.0 knot over the ground will apply in the concerned zone(s) to all vessels engaged in commercial fishing activities above 13.0 m in length overall (LOA). The speed restriction will be in effect for 15 days after the day on which the whale was detected. In the event of a new North Atlantic right whale detection occurring in the last 7 days of the 15-day slowdown period, the speed restriction will be extended for an additional 15 days from the date of the new detection. This would continue until no North Atlantic right whales are detected. The buffer zones associated with the static zones are located 5 nautical miles north and south of their adjacent border in waters less than 36.57m deep.

Dynamic shipping zones

There are 5 dynamic shipping zones (DSZ) located in the Traffic Separation Scheme (TSS) north and south of Anticosti Island: A, B, C, D and E.

Speed restrictions in the dynamic shipping zones

When a North Atlantic right whale is detected in a dynamic shipping zone or in the buffer zones, located 5 nautical miles south or 2.5 nautical miles from the eastern and western edges of the dynamic shipping zones:

When a NAVWARN is issued implementing a speed restriction in one or more dynamic shipping zone(s), vessels above 13.0 m in length (LOA) must not exceed a speed of 10.0 knots over the ground. Even though dynamic shipping zones overlap with static zones, vessels can travel at a safe operational speed in dynamic shipping zones when they are not under speed restriction. Mariners are encouraged to take into consideration the potential for their vessel striking North Atlantic right whales when considering a safe operational speed during navigation.

The speed restriction in the dynamic shipping zone(s) will be in effect for 15 days from the date of detection. In the event of a new North Atlantic right whale detection occurring in the last 7 days of the 15-day slowdown period, the speed restriction will be extended for an additional 15 days from the date of the new detection. This would continue until no NARW are detected. When a speed restriction is extended due to a new North Atlantic right whale detection, it should be noted that, contrary to previous years' operations, no new NAVWARN will be issued. The initial NAVWARN will remain in place until a NAVWARN lifting the speed restriction is published.

Please refer to Schedule 2 for the coordinates of dynamic shipping zones.

Seasonal management areas

Seasonal management area 1 (SMA-1) and seasonal management area 2 (SMA-2) are speed restriction areas located north and south of dynamic shipping zone E, respectively.

Within seasonal management areas, vessels above 13.0 m in length (LOA):

Please refer to Schedule 3 for the coordinates of seasonal management area 1 and 2.

Restricted area

In the summer months, an important proportion of the total North Atlantic right whale population gathers for feeding and surface activity near the Shediac Valley. Since this makes the North Atlantic right whale more susceptible to vessel collisions, a mandatory restricted area will be implemented in and near the Shediac Valley and will come into force once 80% of the restricted area is closed to fishing for the season as per the Department of Fisheries and Oceans' (DFO) right whale closure protocol, or at the latest on June 15, 2026. The restricted area will be lifted on September 25, 2026, unless North Atlantic right whale detections are reported in high number, which would extend the restricted area beyond September 25.

The size and location of the area are determined based on historical detection data of North Atlantic right whales. All necessary details can be found in the Interim Order for the Protection of North Atlantic Right Whales in the Gulf of St. Lawrence, 2026. Triggering and lifting of the restricted area will be communicated to mariners through NAVWARNs and notices to fish harvesters.

Vessels above 13.0 m in length (LOA) will be required to:

The following exceptions will apply to the restricted area. The following listed vessels can travel through the area at not more than 8.0 knots over the ground:

The following vessels can travel through the restricted area at a speed over 8.0 knots, but below 10.0 knots over the ground as required by the static speed restriction zone:

Please refer to Schedule 4 for the coordinates of the restricted area.

Report of death or injury

In the event that at least 1 North Atlantic right whale is reported dead or injured in the Gulf of St. Lawrence in a zone or area where there is no NAVWARN in effect, a speed restriction of 10.0 knots over the ground for vessels above 13.0 m in length overall (LOA) will be implemented in the concerned zone(s) or area(s) for 15 days from the time the NAVWARN comes into effect.

Inclement weather exception

Mariners will be notified in advance via a NAVWARN should the speed restriction status change in any zone or area, due to inclement weather.

Within any zone or area that is no longer subject to a speed restriction due to adverse weather conditions, mariners may proceed at a safe operational speed, but are encouraged to take into consideration the potential for their vessel striking North Atlantic right whales when determining that speed during navigation.

*Non-excepted vessels are still prohibited from transiting through the restricted area.

Voluntary seasonal slowdown in Cabot Strait

To coincide with the North Atlantic right whales entering and exiting the Gulf of St. Lawrence in large numbers, a voluntary seasonal slowdown is being put in place in Cabot Strait from April 22nd to June 30th, 2026, and from September 2nd to November 15th, 2026.

Please refer to Schedule 5 for the coordinates of the voluntary seasonal slowdown in the Cabot Strait.

Roseway Basin – Area to be avoided

The Roseway Basin, located approximately 20 nautical miles south of Cape Sable Island, Nova Scotia, is a critical habitat for North Atlantic right whales, which have been observed to gather in the area on a seasonal basis in Canadian waters. This critical habitat is also located near key shipping routes. In 2007, Canada, with the support of many groups with varied interests, proposed to the International Maritime Organization (IMO) the establishment of a seasonal Area to be Avoided in the Roseway Basin to protect North Atlantic right whales, which IMO accepted and adopted.

To reduce the risk of vessels colliding with North Atlantic right whales, it is recommended that vessels of 300 gross tonnages and more, in transit during the period of June 1 through December 31, avoid the Roseway Basin area. Smaller vessels are also encouraged to avoid passage through this area. If passage is necessary within the Area to be Avoided, it is recommended that all mariners decrease their vessel speed to no more than 10 knots, when safe to do so.

Please refer to Schedule 6 for the coordinates of Roseway Basin.

Bay of Fundy – Voluntary slowdown

The Grand Manan Basin located in the Bay of Fundy is identified as a critical habitat for the North Atlantic right whale. When North Atlantic right whales are detected in the Bay of Fundy shipping lanes and near the Grand Manan Basin area (see sectors 1 and 2 on Canadian Coast Guard's map), the Bay of Fundy Vessel Traffic Services will ask vessels to voluntarily slowdown to 10 knots via VHF channel 12 or 14 at corresponding Calling-in-Points.

NAVWARN broadcasts

The Canadian Coast Guard's Marine Communications and Traffic Services Centres (MCTS) issue NAVWARNs:

Mariners must ensure they have accurate and up-to-date information about the protection of the North Atlantic right whale, as in all applicable NOTMARs and NAVWARNs.

Outbound vessels will receive NAVWARNs

Inbound vessels will receive NAVWARNs

Vessels in transit will receive NAVWARNs

MCTS Centres will broadcast NAVWARNs continuously throughout the season on Continuous Marine Broadcast.

It should be noted that, contrary to previous years' operations, reminders sent to vessels in transit 10 nautical miles before entering a speed restriction zone will no longer be transmitted.

Vessel operators are required to monitor broadcasts by the Canadian Coast Guard's Marine Communications and Traffic Services network for the most up to date information.

Aids to navigation

The Canadian Coast Guard broadcasts virtual Automatic Identification System (AIS) aids to navigation (AIS AtoN) in specific areas. These aids may notify mariners of dynamic shipping zones and/or seasonal management areas subject to speed restrictions.

Each zone is delimited by 4 to 6 virtual AIS AtoN, which can be displayed on a ship's navigation equipment, such as:

The Canadian Coast Guard broadcasts the virtual AIS AtoN only when a speed restriction is in effect in one or more zones.

Mariners must select the virtual AIS AtoN symbol to view a message such as “SectA1 Spd Lim 10 kt.” This message refers to a speed restriction in effect for a specific zone.

Note:

This system is not the primary method of communicating this information.

Compliance and enforcement

Vessels must comply with the Interim Orders made pursuant to the Canada Shipping Act, 2001, and any NAVWARNs broadcasted and published by the Canadian Coast Guard relating to the Interim Orders, aimed at regulating the navigation for the purposes of protecting the North Atlantic right whales.

If a vessel does not comply with the Interim Orders or instructions in the NAVWARNs related to the Interim Orders, the vessel could face:

If a vessel appears to have violated the speed restriction, Transport Canada Marine Safety inspectors will review all information provided through AIS and seek an explanation from the master.

No exemptions to the speed restriction will be granted in advance. However, if a deviation from the speed restrictions is necessary for safety reasons, the following information must be entered into the bridge logbook:

For any deviation, Transport Canada will review and consider reasons such as:
