As the Supreme Court of Canada prepares to deliver its decision in Lundin Mining Corporation v Dov Markowich, the legal community and corporate stakeholders are closely watching for implications that may redefine the concept of "material change" within Canadian securities law. This case presents a pivotal moment that could reshape how companies disclose information to shareholders, particularly in the mining and oil and gas sectors, where operational risks and environmental concerns are ever present and unavoidable.

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.
