PDF Version: The Next Shoe Drops. The Northback (Grassy Mountain) Interests File an International Investment Law Claim Against Canada

In December 2024, the Australian parent companies of Northback Holdings (Northback) filed a Request for Arbitration (RFA) with Canada under the terms of the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP or Agreement) alleging breach of Canada’s investment obligations under that Agreement. The claim follows the rejection of the Grassy Mountain coal project by a joint federal–provincial review panel and subsequent domestic litigation. The case is part of a broader trend of investor-state dispute settlement (ISDS) claims challenging environmental decision-making in resource projects.

PDF Version: The Proposed Co-operation Agreement on Environmental and Impact Assessment between Canada and Alberta

On March 6, 2026 the Governments of Canada and Alberta released a draft co-operation agreement on “Environmental and Impact Assessment”, thereby leading the way to fulfilling one of the undertakings contained in the Memorandum of Understanding on Energy (MOU) signed by the two governments on November 27, 2025. The MOU committed the parties to “Negotiate a cooperation agreement on impact assessments on or before April 1, 2026, that reduces duplication through a single assessment process that respects federal and provincial jurisdictions.” The Draft Agreement is open for comment until March 26, 2026.

Matters Commented On: (1) Annual Report of the Permanent Engineering Board (PEB) to the Governments of the United States and Canada under the terms of the Columbia River Treaty for the period of October 1, 2023 – September 30, 2024, May 16, 2025, and (2) Flood Risk Operating Plan (FROP) for the Columbia River Treaty, June 26, 2025

PDF Version: Continuing Implementation of Revisions to the Columbia River Treaty

The Columbia River Treaty (CRT) entered into force in September 1964. While the CRT has no expiry date, certain terms of the CRT, specifically the flood control provisions of the treaty, were scheduled to change automatically on the treaty’s sixtieth anniversary (September 16, 2024) in a way that would provide the United States far less certainty as to future upstream flood control operations in Canada. For this, and a number of other reasons, the US and Canada were motivated to modernize the CRT and to that end, and as highlighted in previous posts on ABlawg, the governments of Canada and the United States entered into a non-binding agreement in principle (AiP) in July 2024 outlining proposed changes to the Columbia River Treaty (CRT) (see posts on the AiP here and here).

Case Commented On: Obligations of States In Respect of Climate Change, Advisory Opinion of the International Court of Justice, July 23, 2025

PDF Version: What Are the Implications of the International Court’s Climate Change Advisory Opinion for Provinces?

ABlawg has already published posts on constitutional climate change litigation in Canada (the La Rose case, here) as well as two posts on the important unanimous Advisory Opinion (AO) of the International Court of Justice (ICJ) on Climate Change, here and here. This post assesses the implications of the AO for a province within the Confederation of Canada, specifically a province like Alberta which is a significant producer of carbon fuels and a significant emitter of greenhouse gases: see ECCC, Greenhouse Gas Emissions (2025).
