9. Contaminants

Marine mammals can be exposed to a variety of toxic chemical compounds originating from human activities, mainly through their diet, but also through sediments, water and air in their environment.

Southern Resident Killer Whales are vulnerable to accumulating high concentrations of certain chemicals because they are long-lived apex predators that feed almost exclusively on Chinook salmon. Footnote 39 Footnote 40

St. Lawrence Estuary Belugas have a varied diet and eat many kinds of fish and even some shellfish. They live downstream of the many large urban and industrial centers of the Great Lakes Basin year-round exposing them to a variety of contaminants.Footnote 41

North Atlantic Right Whales feed at a lower level on the food chain than the Southern Resident Killer Whale and the St. Lawrence Estuary Beluga on tiny zooplankton called copepods, making them relatively less vulnerable to accumulating high concentrations of chemicals.

9.1 Summary of Key Themes

Indigenous groups, governments and other stakeholders provided feedback on the threat of contaminants primarily for the Southern Resident Killer Whale. Indigenous groups provided feedback for the St. Lawrence Estuary Beluga.

9.2 What Indigenous Groups Said

With respect to the priority management actions for addressing contaminants, participants suggested:

With respect to engagement of Indigenous groups, participants' suggestions included:

St. Lawrence Estuary Beluga

There is some information of the evolution of contaminants affecting the St. Lawrence Estuary Beluga over time. Some toxic chemicals were banned many years ago, but persist in the marine environment and are still found in St. Lawrence Estuary Belugas. Contaminants are known to interfere with St. Lawrence Estuary Beluga reproduction.

The discussion focused on actions to raise awareness of the sources of contaminants, reduce discharges in beluga habitat, clean up wastewater effluents, and develop oil spill response capacity.

Indigenous participant suggestions included:

9.3 What Governments and Other Stakeholders Said

As a necessary first step to move priority management actions forward to reduce the threat of contaminants, it will be necessary to re-establish or re-invigorate structures and processes and to clarify roles and responsibilities for contaminants in marine mammals. At this time:

Southern Resident Killer Whale

Adequately enforce existing, and/or newly added or expanded, Canadian regulations aimed at reducing toxic chemical compound discharges at source.

This priority action was among those rated as quick wins by participants at the in person/webinar meeting.

Specific suggestions related to regulation and enforcement included:

Participants also discussed the need for clearer roles and responsibilities for the protection of marine mammals from contaminants. They suggested this could begin with a comprehensive stakeholder and situational mapping process to improve understanding of current roles and respective agency enforcement and prioritization processes for chemicals.

Accelerate the rate of compliance with the Canadian Wastewater Systems Effluent Regulations (2012) in wastewater treatment facilities that border the Salish Sea.

The upgrade schedule for facilities that border the Salish Sea is financially constrained and an accelerated rate of compliance with the Canadian Wastewater Systems Effluent Regulations would require additional financial resources, e.g., assistance from the federal government (Infrastructure Canada) or other funding sources.

Participant suggestions included:

Review policies and best management practices for ocean dredging and disposal at sea and modify them to include an examination of Polybrominated Diphenyl Ethers Footnote 51 to minimize contaminant exposure.

This priority management action was rated as a quick win by participants at the in person/webinar meeting.

Participant suggestions included:

Identify or implement new programs that mitigate small scale and/or chronic contaminant spills and leaks and provide support.

Generally, small spills are addressed by provincial and municipal levels of government. However, little is known about where and how programs exist to address this issue sufficiently. Further, the mandate of regional government pertains primarily to health and recreational impacts or effects.

Participant suggestions included:

Ensure that assessment and remediation plans for contaminated sites are planned to reduce the risk of lifetime contaminant exposure in the whale population.

This priority action was among those rated as quick wins by participants at the in person/webinar meeting where there is fulsome data and analysis.

Participant suggestions included:

Develop a spill response plan including training, equipment, and deterrence methods and ensure that the protection of the Southern Resident Killer Whale population and their habitat is made a high priority in spill response and monitoring protocols in Canada.

Current initiatives are underway to help prevent, respond to and mitigate the impact of oil spills on the Southern Resident Killer Whale population. Participants were not clear on the federal government's role in the context of emergency response planning relative to other partners.

Suggestions included:

Form an interagency contaminants working group to identify roles and responsibilities for actions to reduce the impacts of contaminants on Southern Resident Killer Whales and their environment.

Given many of the priority actions are outside the current mandate or jurisdiction of Fisheries and Oceans Canada, it was recognized that there is high value in forming a new interagency contaminants working group. The objectives of this working group should include: increasing capacity for action on contaminants and improving communication and facilitating collaborative action.

Provincial and United States government participants were interested in the interagency working group approach and discussed how best to establish the group.

9.4 What the General Public Said

The Let's Talk Whales online portal included an open-ended question designed to ask for opinions on the actions identified by scientists in the Phase 1 science assessment that aimed at abating the threat of contaminants. The actions presented within the question were:
