Years after an insolvency proceeding is closed, can a solvent co-lessee/working interest participant (WIP) still be on the hook for their former partner’s share of unpaid Crown royalties? A recent Alberta Court of Appeal decision to allow an appeal in <a href="https://www.canlii.org/en/ab/abca/doc/2025/2025abca181/2025abca181.html">Spartan Delta Corp v Alberta (Energy and Minerals), 2025 ABCA 181</a> [Spartan Delta], raises concerns around whether the answer to such question can be 'yes'. The oil and gas industry is closely tracking the outcome of this appeal (anticipated to be heard in Fall 2025) on the basis that if the appeal were to be granted it would create uncertainty for upstream oil & gas joint interest owners as to the impact of insolvency proceedings on existing liabilities (and would have implications for purchasers and WIPs alike in relation to oil & gas M&A out of insolvency proceedings).

In late May, the Supreme Court of Canada (the SCC) denied an application for leave to appeal a decision of the Court of Appeal of Alberta, which, in turn, had denied leave to appeal of the decision of the Court of King’s Bench of Alberta in Re Mantle Materials Group, Ltd, 2023 ABKB 488 (Mantle KB). The decision in Mantle KB held that the interests of secured creditors are subordinate to environmental obligations pursuant to the Environmental Protection and Enhancement Act, thus confirming that the priority of environmental obligations determined by the SCC in Orphan Well Association v Grant Thornton Ltd, 2019 SCC 5 applies beyond the oil and gas industry.

This week’s highly anticipated decision of the Alberta Court of Appeal in Qualex-Landmark Towers Inc v 12-10 Capital Corp, 2024 ABCA 115 limits the application of Orphan Well Association v Grant Thornton Ltd, 2019 SCC 5 to regulators inside formal insolvency proceedings rather than private litigants and denies a common law "super priority" for environmental obligations of private litigants over secured claims.

Private investment in the defence sector is accelerating as governments realign policy priorities and expand support for dual-use and DefTech innovation. Canada&rsquo;s 2025 Budget and long-term spending commitments are reshaping the industry, driving new opportunities across AI, cyber, space, advanced manufacturing and critical infrastructure. With global capital flowing into defence technology and structural reforms underway to modernize procurement, the sector is rapidly transitioning from fragmented to fully investable.

On November 4, 2025, the Alberta Energy Regulator released AERH2S, an updated version of its computer model for calculating Emergency Planning Zones (EPZs) for sour gas applications. AERH2S replaces the longstanding ERCBH2S model and is available for immediate use by industry. According to AER Bulletin 2025-34, the use of AERH2S will become mandatory for all applications filed under Directive 056: Energy Development Applications and Schedules, including amendment applications, starting January 1, 2026. The continued use of ERCBH2S is permitted for updates to existing EPZs (and any EPZs established before January 1, 2026) under Directive 071: Emergency Preparedness and Response until further notice.

In McPherson v Global Growth Assets Inc., the Ontario Superior Court interpreted the no-reprisal provisions of the Securities Act for the first time, awarding more than $5.3 million to a CEO who was terminated after raising compliance concerns. The decision underscores the strength of the Act&rsquo;s protections for employees who engage in protected activities and highlights the significant risk to employers of taking disciplinary action without clear, documented justification.
