Regulatory Bulletin, October 2023

Supreme Court of Canada Rules Impact Assessment Act Unconstitutional

The Supreme Court of Canada released its judgment in consideration of the constitutionality of the federal environmental assessment scheme under the Impact Assessment Act (IAA), enacted by Parliament in 2019. It is expected that this ruling will fundamentally alter the scope of federal assessment and decision-making over the vast majority of major projects that are located wholly within a province, such as critical minerals mines, upstream oil production (including oil sands), and pipelines.

Furthermore, the Canada Energy Regulator details approvals of pipeline projects including the Trans Mountain Expansion Project route deviation and the NorthRiver Midstream Northeast British Columbia Connector Project.

In addition to these developments, this update includes details surrounding the newly proposed Draft Directive 0XX: Rock-Hosted Mineral Resource Development by the Alberta Energy Regulator (AER), as well as updates to the AER mandatory closure spend quotas for 2024.
