The question of ‘what constitutes reasonable notice’ is one of the most frequently litigated issues in employment law. There are numerous decisions from every level of court in Ontario which discuss the obligations of an employer to provide a reasonable period of notice to dismissed employees. However, it is a relatively rare occurrence that the Court deals with the inverse – the reasonable period of notice due to an employer by an employee who resigns. While most of us are familiar with the old adage of giving your ‘two weeks’ notice, the recent decision in Gagnon may call into question the sufficiency of such short notice.
