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.

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 Tax Court of Canada allowed ExxonMobil Canada Resources Company&rsquo;s appeal in a significant transfer pricing dispute concerning the deductibility of feasibility study costs related to a proposed Alaska-to-North America natural gas pipeline project. The Court found that the costs were incurred for the purpose of earning income and rejected the Minister&rsquo;s transfer pricing adjustments and Part XIII tax assessment. The decision provides important guidance on transfer pricing analysis, the application of the OECD Guidelines and the evidentiary role of expert testimony in tax disputes.
