The Supreme Court of Canada will hear Pharmascience Inc v Janssen Inc on October 9, 2025, a case that could reshape the scope of patentable subject matter in Canada. At issue is whether a dosing regimen for a pharmaceutical product constitutes an unpatentable method of medical treatment or a valid invention under the Patent Act. The Federal Court and Federal Court of Appeal upheld the patent&rsquo;s validity, but Pharmascience has challenged this position. With several industry groups granted intervenor status, the case is expected to have significant implications not only for the pharmaceutical industry but also for broader questions of what qualifies as an &ldquo;invention,&rdquo; including computer-implemented and AI-related technologies.

In the context of corporate debt, 'liability management' refers to a company taking steps to manage its existing debt obligations. This often involves a combination of one or more open market repurchases, redemptions/repayments, consent solicitations, tender offers or exchange offers and may involve other transactions. A repurchase of debt from a holder is one of the most straight-forward examples of liability management.

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.
