The Supreme Court of Canada has released its much-anticipated decision in Lundin Mining Corp. v. Markowich, 2025 SCC 39, clarifying the definition of a "material change" under securities law and providing guidance on when a public company must disclose information to the market. The decision will have broad implications for public companies, their directors, officers, shareholders and other market participants.

The Ontario Court of Appeal&rsquo;s decision in Binance v. OSC clarifies the limits of the OSC&rsquo;s investigative powers and the Charter protections available in securities investigations. While the Court rejected a constitutional right to challenge a summons before compliance, it found the summons issued to Binance overbroad and unconstitutional. The ruling offers important guidance for market participants on regulatory scrutiny, the scope of document production, and the viability of judicial review.

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.

The Supreme Court of Canada&rsquo;s decision in Emond v Trillium Mutual Insurance Co clarifies how insurance policies are interpreted when endorsements enhancing coverage conflict with policy exclusions. The Court confirmed that a guaranteed rebuilding cost endorsement does not extend coverage to costs expressly excluded, highlighting potential gaps for homeowners and the importance of reviewing policies holistically.

Recent changes to the Commissioner of Lobbying&rsquo;s interpretation of the federal Lobbying Act significantly lower the threshold for mandatory lobbyist registration. As of January 2026, organizations may be required to register if employees collectively spend as little as eight hours lobbying within a four-week period, including preparation and written communications. This update has important compliance implications for corporations and other organizations engaging with federal public office holders.

In Martin v. Alphabet, the Competition Tribunal issued its first decision interpreting the new public-interest pathway for private access under section 103.1(7) of the Competition Act. While affirming an intention to broaden access, the Tribunal articulated a flexible but rigorous three-part framework that places real weight on evidence, genuine interest and the applicant&rsquo;s capacity to prosecute complex competition cases. The decision underscores that public interest alone is insufficient without a coherent, Canada-focused evidentiary record and a credible litigation plan.
