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.

Bill C-31 proposes significant amendments to the Canada Labour Code that would prohibit most post-employment non-compete clauses and potentially other employment-related restrictions in federally regulated workplaces. While the legislation has not yet been enacted, employers should begin assessing the potential impact of the proposed changes, including the limited exemptions available for certain business transactions and senior executive roles.
