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.

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.
