Mackenzie Valley Screening and Exemption Updates

Summary#

These are final changes to the Preliminary Screening Requirement Regulations and the Exemption List Regulations under the Mackenzie Valley Resource Management Act. The amendments update which permit applications in the Mackenzie Valley need an environmental preliminary screening and which small or low‑impact activities are exempt. The rules took effect on March 25, 2024.

What it does#

• Replaces and updates Schedules 1 and 2 of the Preliminary Screening Requirement Regulations to match current federal and territorial laws and to remove outdated references.
• Updates the Exemption List Regulations by:
  • Adding a definition for “Northwest Territories territorial park.”
  • Specifically exempting certain developments located in national parks, national historic sites, and Northwest Territories territorial parks from preliminary screening because their impact on the Mackenzie Valley is considered insignificant.
  • Clarifying that repair and maintenance (not just construction) of sidewalks, boardwalks and parking lots can be exempt when done more than 30 m from water and the parking lot holds 30 or fewer automobiles.
  • Allowing signs with a surface area up to 25 m2 to be constructed, installed or modestly changed without screening.
  • Stating that developments that have already completed a preliminary screening or other federal environmental assessment and have not been modified do not need a new preliminary screening.
• Removes or amends some specific items in the exemption lists (some sections of Schedule 2 are repealed) to reflect modern standards and laws.

Who's affected#

• Project proponents and developers seeking permits, licences or authorizations in the Mackenzie Valley region.
• Government groups and regulators involved in permitting and environmental review, including Parks Canada, Crown‑Indigenous Relations and Northern Affairs Canada, and the various Mackenzie Valley land and water boards.
• Resource sectors that apply for permits in the area (mining, oil and gas, pipelines, forestry and related industries).
• Indigenous governments and communities in the Mackenzie Valley who participate in or are affected by environmental screening and land‑use decisions.
  If it’s unclear whether a specific activity is affected, proponents should check the updated regulations or contact the relevant regulator.

Why it matters#

• The updates bring the screening and exemption lists up to date with current federal and territorial laws. That reduces confusion about which projects need environmental review.
• Several small or routine activities (for example, repairs to boardwalks, parking lots with up to 30 spaces, and modest signs up to 25 m2) are more clearly exempted. That can speed approvals and lower costs for small projects.
• By recognizing prior screenings and modern law names and references, the changes aim to prevent unnecessary repeat screenings and legal gaps while keeping projects with potential significant impacts subject to review.
• Because these are technical updates rather than new policy, the government says they do not add new costs to proponents.
