Fiduciary Employees in Ontario: What the Duty Means, When It Applies, and What Happens When It Is Breached

Are all senior employees fiduciaries in Ontario?

No. Most employees including most managers and many senior executives are not fiduciaries. Courts apply a demanding three-part test requiring vulnerability, entrusted discretion over fundamental interests, and a relationship of trust and confidence. Job title and seniority are relevant but not determinative. Employers frequently overstate fiduciary status to gain leverage in disputes, and courts examine the actual nature of the relationship rather than how the employer characterizes it.

Can I be fired for cause for breaching a fiduciary duty in Ontario?

Yes a genuine breach of fiduciary duty can support termination for cause, which means no notice and no severance. However, the employer must establish both that the employee was actually a fiduciary and that the specific conduct constituted a breach. Courts do not accept employer characterizations uncritically. An employee terminated for alleged fiduciary breach who disputes their fiduciary status has a viable wrongful dismissal claim if the employer cannot prove the status applies. Get legal advice before responding to any termination in these circumstances.

Do fiduciary duties continue after employment ends in Ontario?

In some circumstances yes. While non-fiduciary employees are generally free to compete after leaving (subject to any valid contractual restrictions), fiduciary employees may have ongoing post-employment obligations that restrict certain conduct even without an express non-compete clause. The scope and duration of post-employment fiduciary obligations depends on the specific facts. This is one of the most important reasons to get legal advice before leaving a senior role or joining a competitor.

What if my employer wrongly claims I am a fiduciary in Ontario?

An employer's characterization of your role as fiduciary is not legally binding. Courts determine fiduciary status based on the actual nature of the employment relationship not what the employer says or what a contract labels it. Where your employer is using a fiduciary claim to justify a for-cause termination, withhold severance, or threaten legal action against you, get legal advice immediately. The claim may not withstand scrutiny, and a wrongful dismissal or wrongful withholding of severance claim may be available.

How do fiduciary duties interact with non-compete and non-solicitation clauses?

They are distinct but overlapping. Fiduciary duties arise from the nature of the employment relationship and may apply even without an express contractual clause. Non-compete and non-solicitation clauses are contractual restrictions that must be reasonable in scope, geography, and duration to be enforceable. Where an employee is both a fiduciary and has signed a non-compete, both sets of obligations apply. Where no contractual restriction exists, the fiduciary's post-employment obligations are assessed on the facts. A lawyer can advise on which obligations apply to your specific situation.
