In Ontario, common law—the body of law developed through judicial decisions—plays a crucial role in shaping employment practices and principles. Employment common law changes on a very regular basis and it is critical to keep up to speed as an employer or an employee. Here is a look at some of the key recent common law changes to constructive dismissal in Ontario employment law.


Constructive Dismissal


Constructive dismissal occurs when an employer makes unilateral changes to fundamental terms of employment, leading the employee to resign. Recent cases have clarified what constitutes constructive dismissal, what is considered a fundamental change and the circumstances under which employees can claim it.



The Ontario Court of Appeal ruled that significant changes to an employee’s duties and compensation can constitute constructive dismissal. In this case, the court found that a substantial reduction in pay and responsibilities amounted to a breach of the employment contract and therefore constituted constructive dismissal. Constructive dismissals are more commonly awarded to more senior and tenured employees.


  • Employer Implications: Employers should tread carefully when modifying job roles, compensation, or working conditions or even creating workplace accommodations. Employees must remain at the same level of responsibility and same level of pay, any decrease in either would be considered constructive dismissal.


  • Employee Implications: Employees should be aware that substantial negative changes to their employment terms might allow them to claim constructive dismissal.
