The Government of Canada outlines 2025 measures to protect Southern Resident killer whales
The Government of Canada recognizes that Southern Resident killer whales continue to face imminent threats to their survival and recovery, and that protecting these iconic marine mammals requires comprehensive and immediate action. The 2025 management measures focus on addressing the three primary threats to Southern Resident killer whales: acoustic and physical disturbance; prey availability and accessibility; and contaminants.
1. Acoustic and physical disturbances from vessels
Approach distance
Vessels must stay at least 400 metres away and must not impede the path of all killer whales year-round in Southern British Columbia coastal waters between Campbell River to just north of Ucluelet. Commercial whale-watching and ecotourism companies who receive an authorization from the Minister of Transport and Internal Trade will be able to view non-Southern Resident killer whales (such as transient (Biggs) killer whales) from 200 metres, given their expertise in identifying different types of killer whales.
If a vessel finds itself within 400 metres of a killer whale, they are asked to turn off fish finders and echo sounders and put the engine in neutral when safe to do so to allow animals to pass.
If a vessel is within 1,000 metres of a killer whale, they are asked to reduce speed to less than seven knots when safe to do so to lessen engine noise and vessel wake.
To address imminent threats to Southern Resident killer whale survival and the Government of Canada's commitment to develop longer-term actions for the recovery of Southern Resident killer whales, Fisheries and Oceans Canada proposes to increase the approach distance to 1,000 metres for Southern Resident killer whales through amendments to the Marine Mammal Regulations under the Fisheries Act. The process for amending the Marine Mammal Regulations remains ongoing. The exact scope and implementation of any regulatory measures will be informed by future consultations with directly affected First Nations, Wildlife Management Boards, stakeholders, and other affected parties upon publication of the draft regulation in the Canada Gazett e, Part 1. The consultations are intended to seek feedback on the scope of these measures and identify and mitigate, to the extent possible, potential impacts.
Speed restricted zones
The 2025 measures continue the mandatory speed restricted zones near Swiftsure Bank, co-developed with the Pacheedaht First Nation.
From June 1 until November 30, 2025, all vessels must slow down to a maximum of 10 knots over ground in two speed restricted zones near Swiftsure Bank. The first area is in the Protected Fisheries Management Area 121-1 and the second speed restricted zone is located near the mouth of the Nitinat River from Carmanah Point to Longitude 125 degrees west.
Exemptions are in place for the following: vessels in distress or providing assistance to a vessel or person in distress vessels avoiding immediate or unforeseen danger government or law enforcement on official business permitted research if the research requires higher speed; and a sailing vessel proceeding under sail and not being propelled by machinery
While the mandatory speed restricted zones and the voluntary slowdowns coordinated by the Vancouver Fraser Port Authority's Enhancing Cetacean and Habitat Observation (ECHO) Program both cover known foraging areas at or near Swiftsure Bank, they are separate measures from each other and take place in different locations. The ECHO Program slowdown at Swiftsure Bank is a voluntary ship slowdown which takes effect across 23 nautical miles in both the outbound and inbound lanes at Swiftsure Bank.
Vessel restricted zones (Formerly Interim sanctuary zones)
Formerly known as Interim Sanctuary Zones, Vessel Restricted Zones create spaces of refuge for the whales. The location of these zones is based on scientific and Indigenous knowledge of historically important foraging areas for Southern Resident killer whales.
From June 1 until November 30, 2025, no vessel traffic or fishing activity is allowed in vessel restricted zones off the southwest coast of South Pender Island and the southeast end of Saturna Island. Exceptions will be allowed for emergency situations and vessels engaged in Indigenous food, social, and ceremonial fisheries.
To ensure the safety of those operating human-powered vessels, a 20-metre corridor next to shore will allow kayakers and other paddlers to transit through these zones. If a killer whale is in the sanctuary at the time, paddlers must remain 400 metres away from the whales.
Voluntary speed reduction zone
In 2025, Transport Canada is continuing with a voluntary speed reduction zone in Tumbo Channel, in effect once again from June 1 to November 30, 2025. When travelling through this area, it is recommended that vessels reduce their speed to 10 knots, when safe to do so.
2. Prey availability
Chinook, chum and coho salmon are an essential part of the Southern Resident killer whale diet. Last year's process developed and consulted on salmon fisheries management measures for both 2024 and 2025, which were announced on June 3, 2024.
To address the limited availability of prey, Fisheries and Oceans Canada is continuing a combination of fishing restrictions in key foraging areas within their critical habitat, along with voluntary measures coastwide. These measures will reduce disturbance and competition for salmon between fish harvesters and killer whales. Opportunities will be available for non-salmon related recreational and commercial fisheries, for Indigenous food, social and ceremonial harvest as well as Treaty-defined fishing access.
For 2025, the following measures will help protect the whales' access to salmon and minimize disturbance in key foraging areas:
Area-based closures in Southern Resident killer whale key foraging areas for recreational and commercial salmon fisheries: around the Strait of Juan de Fuca (portions of Subareas 20-4 and 20-5) in effect from August 1 until October 31 Swiftsure Bank (portions of Subareas 20-1, 21-0, 121-1 and 121-2) in effect from July 15 until October 31 around the mouth of the Fraser River (a portion of Subarea 29-3) from August 1 to September 30
The Southern Gulf Islands area-based closures (Subarea 18-9 and portions of 18-2, 18-4 and 18-5) will be in effect as early as May 1, based on confirmed presence of Southern Resident killer whales. These closures will be in place until November 30, 2025.
All fishers are encouraged to temporarily cease fishing activities (e.g., do not haul in gear where appropriate) when killer whales are within 1,000 metres. This voluntary measure is in place year-round throughout Canadian Pacific waters.
To address the ongoing imminent threats to Southern Resident killer whale survival and recovery, proposed adjustments to the Southern Resident killer whale commercial and recreational salmon fishing closures are being considered and consulted on for 2025 and or 2026 under the Fisheries Act to address the threat of reduced prey availability. The exact scope and implementation of any regulatory measures will be informed by consultations with directly affected First Nations, Wildlife Management Boards, industry stakeholders, and other affected parties. The consultations are intended to seek feedback on the scope of these measures and identify and mitigate, to the extent possible, potential impacts.
Enhancing Cetacean Habitat and Observation Program (ECHO)
For the ninth year in a row, the Vancouver Fraser Port Authority-led Enhancing Cetacean and Habitat Observation (ECHO) Program will coordinate large-scale threat reduction measures to support the recovery of endangered southern resident killer whales. These measures will include a ship slowdown in Haro Strait, Boundary Pass and Swiftsure Bank, and a route alteration in the Strait of Juan de Fuca. Full details of the ECHO Program's voluntary measures, including dates, target slowdown speeds and location coordinates, are available on the ECHO Program's website (www.portvancouver.com/echo).
3. Contaminants
Considering the persistence of many contaminants in the environment, the Government of Canada and its partners continue to progress on long-term actions to support Southern Resident killer whale recovery in the following areas:
The Government of Canada has also developed and updated the online Pollutants Affecting Whales and their Prey Inventory Tool, which maps estimates of pollutant releases within the habitats of Southern Resident killer whales and their primary prey, Chinook salmon. This tool will help model the impacts of additional mitigation measures and controls.
To better understand the threat of contaminants and to provide input into government action, the Government of Canada leads a technical working group focused on contaminants in the environment. This group is comprised of key partners from all orders of government, academia and non-governmental organizations and:
has identified priority contaminants of concern;
has provided recommendations for the long-term actions to support Southern Resident killer whale recovery; and
conducts important monitoring and research, to identify contaminant exposures to Southern Resident killer whales, their habitat and their prey.
In addition, the group continues to recommend and develop environmental quality guidelines for the protection of Southern Resident killer whales and their prey and compares them with monitoring data to identify areas of potential risk for further action.
Compliance with management measures depends on public awareness. The Government of Canada continues to collaborate with educational organizations, environmental groups, Indigenous partners, and government bodies to raise awareness of the Southern Resident killer whale protection measures through public education and outreach efforts.

Government of Canada Provides Early Decision on Flood Diversion Project in New Brunswick
June 5, 2025 -Ottawa-Impact Assessment Agency of Canada The Impact Assessment Agency of Canada (IAAC) has completed its review of the Sussex Region Flood Diversion Project, a new permanent flood control management system in Sussex, New Brunswick, and determined that its potential adverse effects within federal jurisdiction would be limited or addressed through other means. The proponent, the Town of Sussex, may now move forward with obtaining any necessary authorizations and permits from federal and provincial authorities. To arrive at its section .16 decision under the Impact Assessment Act , IAAC engaged other jurisdictions, federal experts, stakeholders, the public, and Indigenous Peoples to review the project description and identify potential impacts to federal jurisdiction and ensure they can be appropriately mitigated. After a careful review of these issues, the proponent's response and other factors, including comments from the public, IAAC determined that the potential adverse effects within federal jurisdiction would be limited or addressed through existing federal and provincial laws and regulations. These include but are not limited to the Fisheries Act , Migratory Birds Convention Act, 1994 , Species at Risk Act , the New Brunswick Clean Environment Act , and the Watercourse and Wetland Alteration Permit under the New Brunswick Clean Water Act . As a result, a more comprehensive impact assessment is not required. The documents and list of factors considered can be found in IAAC's decision with reasons.

BC First Nation builds small island, fisheries officials check for possible habitat damage
A British Columbia First Nation has built up a small artificial island in the tidal shallows of Coles Bay off Vancouver Island, triggering an investigation by fisheries officials into whether it involved habitat destruction and if authorization should have been required. Two yellow excavators could be seen at work last week in the bay, heaping up stones and gravel on top of an existing rock outcrop, in a project the Department of Fisheries and Ocean said was linked to a "clam garden." Nearby resident Richard Smith said he watched dump trucks carry loads of rock to the shore, where the excavators hauled it into the bay, also building a temporary land bridge during the construction process. He said the rock outcrop was previously visible at low tide, but the island is now exposed at all times after the construction, which lasted from May 26 to May 30. The Canadian Press watched the excavators at work on May 30, then saw that they had left the scene later that day. That afternoon, about 20 workers, some wearing outfits with the logo of the Pauquachin First Nation, were on the bay's mud flats spreading what one described as "shell hash." The worker declined to be identified. Shell hash, made of finely ground sea shells, is used in some aquaculture operations to promote growth of mollusks, such as clams. The Department of Fisheries and Ocean was asked by The Canadian Press about the construction last Friday, and on Tuesday the department said in a statement it was "aware of work being undertaken involving excavators and dump trucks to move and stockpile rocks in Coles Bay, BC, to facilitate construction of a clam garden," a traditional form of aquaculture. It said fisheries officers and biologists visited the site on Monday to evaluate the work. "Assessment of the work will determine whether there has been any harmful alternation, disruption or destruction of fish and fish habitat that would require authorization under the Fisheries Act," the statement said, adding that "it would be premature to comment further at this time." Work above the high-water mark occurred on Pauquachin territory, maps show. The First Nation did not respond to questions about the work. But it had previously announced an event in August to build a "traditional sea garden" in Coles Bay, with guests invited to help construct a 250-metre long wall on the tidal flats using "mindfully sourced and prepared rocks" from a quarry. "A traditionally designed sea garden will nurture clam beds, welcome the return of numerous sea life, provide food sustainability, awaken sleeping traditional teachings, harvesting practices and sharing to future generations," a description says on a Pauquachin First Nation website. Shellfish harvesting in Coles Bay was prohibited in 1997 on health grounds because of pollution from septic systems. The Pauquachin First Nation of 423 people along the western shore of the Saanich Peninsula has said the prohibition represents an "infringement" of traditional fishing rights granted under an 1852 treaty. Chief Rebecca David said in a June 2023 letter to the provincial government that government-authorized septic systems represent the "primary source of pollution," calling on Ottawa and Victoria to fulfil obligations under the 1852 treaty by cleaning up the bay so shellfish harvesting can resume. The University of Victoria's Environmental Law Centre said in a report attached to David's letter that the closure of shellfish harvesting had deprived families of a critical food source and "failure to redress the pollution" represents "a grievous breach of treaty rights." David's letter calls for the decontamination of Coles Bay to serve as a "pilot project for developing a systemic approach to decontaminating shellfish beaches in British Columbia." The Ministry of Water, Land and Resource Stewardship said in a statement the province "has supported Pauquachin's efforts to rehabilitate shellfish harvest in Coles Bay through regularly scheduled meetings and other technical support." It did not respond directly to questions about the construction in Coles Bay. The lack of public information about the work has frustrated Smith, who said he is a 'big supporter of reconciliation' and supports 'anything that we can do to assist, co-operate and partner' with First Nations in almost any sphere. "My frustration is really with the enforcement people or the people that are supposed to be governing this, who provide me with no information at all," he said. Smith said this uncertainty is weighing heavily on him given the environmental stakes. "It's the ocean and we all have to protect the ocean," he said. "That's part of our lives … theirs (the First Nation's), everybody's, and I'm constantly out on the beach, cleaning it, pulling tires out of the water." North Saanich Mayor Peter Jones said on Tuesday that neither he nor the council received any notice about the work, but would have to confirm whether the First Nation contacted the municipality. "I know for myself, I have not been contacted," he said, adding the municipality has a "very, very positive and very open" relationship with the First Nation. Jones said he does not know what the First Nation is doing, but said it has been working for a long time with Victoria, Ottawa and the Capital Regional District on restoring clam beds. "This council is very, very hopeful that the (First Nation) can, in fact, restore the clam beds to a level that would make them very, very useful to them," he said. "Again, I hope they are successful, and with regard to what's happening there right now, council and I have no idea." This report by The Canadian Press was first published June 4, 2025.
