The Alberta Court of Appeal has clarified the nature of co-lessee liability for unpaid Crown royalties under the Mines and Minerals Act. In two companion decisions, the Court confirmed that co-lessees are jointly (not jointly and severally) liable, meaning a claim extinguished against one may impact all. The decisions also address how vesting orders and insolvency stays affect the Crown&rsquo;s ability to pursue royalty arrears.

In Royal Bank of Canada v Patterson Dental Canada Inc, the Alberta Court of Appeal clarified how PPSA priority rules apply where assets used in a corporate business are personally owned by a director. The Court confirmed that ownership and registration against the correct debtor are decisive in priority disputes, and provided guidance on the treatment of leases and the proper distribution of holdbacks in insolvency sales.

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.

In Pharmascience v. Janssen Inc., the Supreme Court of Canada reaffirmed that methods of medical treatment remain unpatentable subject matter under the Patent Act because they are directed to the professional skill and judgment of healthcare practitioners. At the same time, the Court upheld the patentability of the dosing regimen claims at issue, clarifying that not all therapeutic or treatment-related claims constitute unpatentable methods of medical treatment. The decision provides important guidance on assessing patent eligibility for pharmaceutical and life sciences innovations in Canada.

On June 17, 2026, the Alberta Court of Appeal unanimously dismissed an appeal by Fort McMurray 468 First Nation challenging an Alberta Energy Regulator decision that the First Nation lacked standing to request regulatory appeals of approvals issued to AdhMor Ltd. for an oilfield waste management facility near Fort McMurray. The decision in Fort McMurray 468 First Nation v Alberta Energy Regulator, 2026 ABCA 197, offers important guidance on what it takes to get in the door at the AER.
