Canada’s Policy for the Conservation of Wild Pacific Salmon

Canada’s Policy for the Conservation of Wild Pacific Salmon (Wild Salmon Policy) was introduced in 2005 by Fisheries and Oceans Canada (DFO) to provide a cohesive, science-based framework for protecting and restoring wild Pacific salmon populations across British Columbia and the Yukon. It was the first federal policy to explicitly prioritize the long-term conservation of wild salmon biodiversity and the ecosystems that sustain them. 

For the first time in federal policy, salmon were considered ‘wild’ if they lived their entire life in the wild and originated from parents that did the same. There was also emphasis on preserving and protecting naturally spawning populations rather than hatchery-raised or farmed salmon. The WSP established a broad suite of principles and goals aimed at ensuring wild salmon remain biologically diverse, abundant, and resilient amid growing environmental pressures.

Core objectives of the Wild Salmon Policy

The WSP is built around three overarching objectives:

• Conserve salmon diversity: Protect the full range of genetically and geographically distinct wild salmon populations, referred to as Conservation Units (CUs).
• Maintain habitat and ecosystem integrity: Safeguard the freshwater and marine environments that salmon depend on throughout their life cycle.
• Ensure sustainable fisheries management: Manage harvest to support long-term population health, ecosystem needs, and cultural, social, and economic values.

Key components

Conservation Units

• A defining feature of the WSP is its focus on Conservation Units (CUs), which are population groupings that reflect irreplaceable ecological and genetic diversity.
• Management decisions were intended to be made at the CU level to preserve this diversity, yet with nearly 400 CUs identified in BC and the Yukon, managing salmon at this scale has proven difficult. As such, grouping CUs into larger Stock Management Units has become a de facto approach for fisheries management.  

Status Assessment Framework

• The policy requires regular monitoring and assessment of each CU to determine biological status (red, amber, green). Assessments are intended to guide management actions, fishing plans, conservation measures, rebuilding plans, and habitat protections.
• The status of a CU is determined using benchmarks. These thresholds can be determined by biological properties of a population and established from metrics like trends in escapement, abundance, and stock recruitments analysis.

Monitoring and Data Requirements

• The WSP emphasizes long-term monitoring of the following data, which are considered essential for informed decision-making: Spawner abundance, habitat condition, population trends, genetic diversity, fisheries impacts

Integrated Planning

• The WSP envisions regional, watershed-based planning processes involving federal, provincial, Indigenous, and community partners. The goal is to align fisheries management, habitat protection, land-use planning, and recovery actions.

Public and Indigenous Participation

• The policy acknowledges the importance of collaborative governance and the central role of Indigenous Nations in salmon stewardship, reflecting legal rights and longstanding cultural relationships with salmon.

Implementation history

Since 2005, DFO has attempted to advance the WSP through:

• Multiple technical guidelines and assessment frameworks
• Development of a singular, 4 year-implementation plan: the 2018-2022 Wild Salmon Policy Implementation Plan
• Incremental progress on CU identification, habitat indicators, and status assessment

However, academics, Indigenous organizations, and non-governmental organizations have frequently noted gaps between policy intention and implementation, including:

• Incomplete CU monitoring and stock assessments
• Limited enforcement of habitat protections
• Fragmented governance and decision-making
• Slow development of integrated watershed plans
• Resource and capacity constraints within DFO and regional partners

Current Context

Wild Pacific salmon face growing pressures that heighten the importance of full policy implementation, including climate change, habitat degradation, fisheries pressure, and impacts from hatcheries and aquaculture.

The WSP remains a foundational framework for salmon conservation in Canada, but its long-term effectiveness depends on sustained monitoring, coordinated governance, transparent decision-making, and clear accountability for implementation.
