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 recent years, the OSC and other regulatory bodies began signaling to public markets that regulators intended to crack down on what they termed abusive short-sellers. Against this backdrop, the OSC brought enforcement proceedings before the Ontario Capital Markets Tribunal (CMT) naming Cormark Securities Inc., Saline Investments Ltd., and individuals as respondents. The proceedings focused on an alleged illegal and abusive short selling scheme. At the conclusion of a lengthy hearing on the merits, the CMT dismissed all of the OSC’s allegations.

The Federal Court dismissed a proposed C$5B class action alleging a nationwide conspiracy to fix generic drug prices, finding no basis in fact and denying certification. The decision underscores the Court&rsquo;s gatekeeping role and confirms that US enforcement actions and generalized market theories are insufficient to support competition claims in Canada without clear, particularized evidence.
