The decision signals a potential shift from contextual materiality analysis and raises challenges for issuers with volatile share prices.<br />

The Ontario Court of Appeal&rsquo;s decision in <em>Binance v. OSC</em> 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.
