2024 management measures to protect Southern Resident killer whales

Southern Resident killer whales have important cultural significance for Indigenous Peoples and coastal communities in British Columbia. These iconic animals face imminent threats to their survival and recovery. Protecting them requires comprehensive and immediate action.

The 3 primary threats to Southern Resident killer whales are:

Canada has laws and regulations in place to address these threats and support the survival of this species, and there are voluntary measures that you can take as well. Effectively ensuring the protection and recovery of Southern Resident killer whales requires a long-term, collective effort. These measures reflect current science and advice from First Nations, Stakeholders, the Indigenous Multi-Nation Group, Indigenous and Multi-Stakeholder Advisory Group, Technical Working Groups, and from public consultations.

Regulations to support Southern Resident killer whales

You must follow Canada's laws and regulations to protect Southern Resident killer whales.

Area-based fishing closures

Chinook salmon are a vital food source for Southern Resident killer whales but wild chinook have declined dramatically in recent years. Fishery management measures aim to help increase the availability of salmon in key Southern Resident killer whale feeding areas.

The following areas will be closed to salmon fishing by both commercial and recreational harvesters.

Fishers are also asked to voluntarily stop fishing (do not haul gear) within 1000m of killer whales in all Canadian Pacific waters as a best practice in the presence of killer whales to reduce competition for their food and to minimize disturbing the animals.

Interim Sanctuary Zones

Interim Sanctuary Zones are in effect from June 1 to November 30 in important areas for Southern Resident killer whales to further reduce acoustic and physical disturbance from vessels.

Vessel traffic (including fishing) will be prohibited in Interim Sanctuary Zones off North Pender and Saturna Islands as per the Interim Order enacted under the Canada Shipping Act. Some exceptions will apply, including emergency situations, vessels engaged in Indigenous food, social and ceremonial fisheries or Indigenous Peoples exercising existing rights.

New for this year, a voluntary Speed Reduction Zone is being implemented in Tumbo Channel. Vessels should reduce speed to no more than 10 knots in this area, when safe to do so.

Speed Restricted Zones

From June 1 until November 30, all vessels are required to slow down to a maximum of 10 knots around Swiftsure Bank:

Some limited exceptions may apply. This measure is mandatory and separate from the voluntary slowdowns for large commercial vessels coordinated by the ECHO Program.

Avoiding whales

Vessels must stay 400m away and may not position a vessel in the path of killer whales in southern BC coastal waters between Campbell River and just north of Ucluelet until May 31, 2025, as per the Interim Order enacted under the Canada Shipping Act. Vessels with a purple ‘Authorized Vessel’ (AV) flag are allowed to be closer to non-Southern Resident killer whales. Do not follow them.

The Marine Mammal Regulations remain in effect year-round. This requires staying:

Voluntary measures to protect Southern Resident killer whales

As well as following Canada’s laws and regulations, there are also voluntary measures that you can take to support the survival of Southern Resident killer whales anytime you’re on or near the water.

Contaminants

The Government of Canada continues to address the threat of contaminants by strengthening regulations and enforcing them, developing guidelines, and increasing research and monitoring. We are now better able to understand the source and quantity of contaminants affecting Southern Resident killer whale and their prey, and to focus our prevention efforts in consequence. As part of our effort to share information and data, the Pollutants Affecting Whales and their Prey Inventory Tool (PAWPIT), an interactive pollutant mapping tool, is available. The tool shows estimates of pollutant releases by all identified sources within a spatial extent that includes the habitats of Northern and Southern Resident killer whales and freshwater areas important for Chinook salmon. The tool also displays estimated ambient contaminant loads in the Fraser River Basin, indicates where environmental quality guidelines were exceeded, and provides the locations of un-remediated contaminated sites.
