Case Commented On: Yahey v British Columbia, 2021 BCSC 1287 (CanLII)
PDF Version: Counting Straws: Yahey v British Columbia and the Future of Cumulative Effects Management in Canada
Much has already been written about the British Columbia Supreme Court’s ground-breaking decision in Yahey v British Columbia, 2021 BCSC 1287 (CanLII) (also referred to as Blueberry River First Nation, BRFN, or simply Blueberry throughout). In Yahey, the Court agreed with the BRFN that, in the context of BFRN’s traditional territory in Northeastern British Columbia, “the cumulative effects of industrial development authorized by [British Columbia] have significantly diminished the ability of Blueberry members to exercise their rights to hunt, fish and trap in their territory as part of their way of life and therefore constitute an infringement of their treaty rights” (at para 3). My colleague Professor Robert Hamilton and former UCalgary Law JD student (now alumnus) Nick Ettinger wrote two outstanding blogs on the decision when it first came out: a first post summarized the decision, while a second focused on Yahey’s standard for treaty infringement, i.e., “meaningful diminishment”. They also published a law review article on the decision: Robert Hamilton and Nicholas P. Ettinger, “The Future of Treaty Interpretation in Yahey v British Columbia: Clarification on Cumulative Effects, Common Intentions, and Treaty Infringement,” 2023 54-1 Ottawa L Rev 109. In this (very) belated post spurred on by a presentation that I gave at an environmental law conference last month, I focus on the Court’s findings with respect to British Columbia’s approach to resource development, and specifically its failure to effectively manage the cumulative effects associated with oil and gas and forestry. In my view, and as further set out below, these findings and analysis are relevant to every level of government in Canada: federal, provincial, territorial, Indigenous, and municipal.
