Athabasca Rainbow Trout Critical Habitat Order

Summary#

The federal government made the Critical Habitat of the Rainbow Trout (Oncorhynchus mykiss) Athabasca River Populations Order: SOR/2021-32 to give legal protection to habitat needed by the Athabasca River populations of rainbow trout. The Order came into force when it was registered on March 11, 2021 and applies to the habitat areas identified in the species' recovery strategy, outside of Jasper National Park.

What it does#

• Triggers the federal legal protection in the Species at Risk Act that makes it illegal to destroy any part of the trout's identified critical habitat outside of Jasper National Park.
• Covers streams and tributaries in the upper Athabasca watershed (the areas mapped in the recovery strategy). It explicitly includes a riparian zone of 30 m measured from the high-water mark on each bank where that zone contains the habitat features the trout need.
• Leaves the part of critical habitat inside Jasper National Park out of the Order because the park portion was already described by the Parks Canada Agency and is subject to the same federal prohibition.
• Reinforces existing protections under the Fisheries Act, and notes that when destruction of habitat cannot be avoided, project proponents may seek permits or authorizations (for example under SARA or the Fisheries Act) that allow certain activities under conditions intended to protect the species.

Who's affected#

• Local communities, land users and people who work or run projects in and near streams in the upper Athabasca watershed.
• Resource industries that operate near streams, particularly the forestry industry, and also mining, oil and gas, and development proponents who may need extra reviews or permits for works near water.
• Indigenous groups with traditional territory in the area. The government consulted a range of groups, including the Alexis Nakota Sioux Nation and representatives such as the Métis Nation of Alberta.
• Fisheries managers and regulators, notably Fisheries and Oceans Canada (DFO), which will oversee permitting and compliance.

Why it matters#

• The Order gives clear, targeted protection to habitat that scientific work identified as necessary for the recovery of a distinct, endangered local form of rainbow trout. That makes it harder for activities to harm spawning, rearing and overwintering areas.
• In practice, people planning work within the designated riparian 30 m zones may need to change plans, apply for permits, or follow conditions to avoid legal trouble. The government says most of the increased burden comes through existing Fisheries Act protections, and it expects the Order itself to have negligible additional regulatory cost.
• For the public, this aims to help recover a threatened fish population and protect water quality and stream health, while creating clearer rules for industries and project reviewers working near those streams.
