Breach of Fiduciary Duty
A breach of fiduciary duty arises when individuals in positions of trust place their own interests ahead of those they are legally bound to protect. Under Canadian fiduciary law, fiduciaries must act with loyalty, good faith, and undivided commitment to another party’s interests. When fiduciaries disregard these duties or engage in conduct that creates a conflict of interest, affected parties may pursue a breach of fiduciary duty claim through the courts.
A fiduciary duty is a legal obligation requiring fiduciaries to act in the best interests of another party. In many fiduciary relationships, one party holds power or discretion over the affairs, property, or rights of another. In these special relationships, fiduciaries must prioritize the beneficiary’s interests and avoid advancing their own interests.
The concept of fiduciary duty has deep historical roots. Elements of the fiduciary doctrine can be traced to roman law, and modern Canadian courts have refined the concept through common law, equitable principles, and evolving fiduciary jurisprudence. These sources collectively form the foundation of modern fiduciary law.
A fiduciary duty occurs when fiduciaries undertake legal obligations to act for the sole benefit of another person or entity. In these situations, fiduciaries must demonstrate undivided loyalty, act honestly, and act in good faith when exercising authority or discretion. In essence, fiduciaries must act solely for the person’s interests, rather than advancing their own interests or pursuing personal gain.
Courts have recognized that fiduciary relationships exist where one party is vulnerable and places trust in another who has power over significant decisions or assets. These fiduciary relations often involve a high degree of reliance and confidence.
In practical terms, a fiduciary duty requires fiduciaries to follow strict fiduciary rules, avoid self-dealing, disclose relevant information, and ensure that any potential conflict of interest is addressed through informed consent.

Various individuals and professionals may owe fiduciary duties depending on the circumstances. Courts examine whether fiduciaries exercise discretion, control assets, or influence important decision making affecting another person.
Common examples of fiduciaries include:
In these roles, fiduciaries may hold authority over financial matters, strategy, or property. Courts recognize that fiduciaries operate in a fiduciary capacity, and therefore must fulfill their fiduciary obligations by prioritizing the best interests of those who rely on them.
In the corporate context, fiduciaries must comply with the standards imposed by corporate governance frameworks. Corporate fiduciaries, including a senior officer, must make business decisions consistent with the corporation’s interests rather than their own interests or personal interests.
Similarly, trustees managing trust assets are legally committed to safeguarding those assets for beneficiaries. When trustees fail to act in accordance with their fiduciary obligations, courts may intervene.
In determining whether individuals hold fiduciary duties, courts often analyze case law and the surrounding legal structures governing the relationship.

A breach of fiduciary duty occurs when fiduciaries fail to meet the high standards imposed by fiduciary law. Courts frequently examine whether fiduciaries acted with loyalty and good faith, or whether their conduct served their own interests instead of the beneficiary’s interests.
Common examples of breach of fiduciary duty include:
A conflict of interest arises when fiduciaries place themselves in situations where their personal interests compete with the person’s interests they are obligated to protect. The no conflict rule requires fiduciaries to avoid conflicts unless they obtain informed consent.
The no profit rule prevents fiduciaries from profiting from their fiduciary position without proper disclosure. When fiduciaries use their authority to obtain personal gain or advance their own self interest, courts may find a fiduciary breach.
Trustees who improperly manage or misappropriate trust assets may commit a breach of fiduciary duty under the Trustee Act and applicable common law principles.
Fiduciaries must disclose relevant facts so beneficiaries can make informed decisions. When fiduciaries conceal financial statements or other relevant documents, a breach of fiduciary duty may arise.
A fiduciary breach may also occur when fiduciaries prioritize their own self interest, influence business decisions for personal advantage, or otherwise advance their own interests rather than the best interests of the person relying on them.
Where a fiduciary fails to meet these standards, courts may conclude that a serious violation of fiduciary obligations has occurred.
A breach of fiduciary duty is considered a serious violation because fiduciaries are entrusted with significant power and discretion. When a breach occurred, courts may scrutinize the fiduciary’s actions closely to determine whether they complied with established fiduciary principles.
Canadian courts emphasize that fiduciaries must exercise undivided loyalty and protect the person’s interests entrusted to them. If a fiduciary fails to meet these obligations, the consequences can include:
In assessing liability, courts may conduct further inquiry into the circumstances surrounding the alleged misconduct. Judicial reasoning often draws upon case law and evolving fiduciary jurisprudence, including guidance from the Supreme Court interpreting fiduciary law in Canada.
Courts applying equitable principles have broad discretion to remedy a breach of fiduciary duty. Remedies are designed not only to compensate victims but also to ensure fiduciaries do not benefit from misconduct.
Common remedies include:
A constructive trust may be imposed where fiduciaries improperly acquire property or profits. Under this remedy, assets are treated as though they were always held for the beneficiary.
Where fiduciaries earn profits through improper conduct, courts may order disgorgement to prevent unjust enrichment.
Victims of a breach of fiduciary duty may receive damages reflecting losses caused by the fiduciary’s actions.
Additional equitable remedies may include rescission of transactions, accounting for profits, or further equitable relief grounded in fiduciary principles.
These remedies ensure fiduciaries remain accountable for their conduct and reinforce the strict standards imposed by fiduciary law.
The time limit for bringing fiduciary duty claims in Ontario depends on the application limitation period and the specific circumstances of the case.
In many situations, a fiduciary duty lawsuit must be commenced within two years of discovering the breach of fiduciary duty. However, courts may examine when the claimant knew or ought to have known that a breach occurred.
In certain circumstances, limitation periods may be affected where fiduciaries concealed misconduct or where the claimant could not reasonably identify the wrongdoing earlier.
Because limitation issues can be complex, parties considering fiduciary duty claims should seek legal advice promptly to preserve their rights and properly navigate the litigation process.
Allegations involving fiduciaries are often complex and fact-intensive. Successfully pursuing or defending a breach of fiduciary duty claim requires careful analysis of fiduciary law, common law, and the unique features of the legal system governing such disputes.
