Many business owners assume that an employee on an approved leave of absence enjoys complete immunity from termination. The reality is more nuanced. Canadian human rights and employment standards legislation does not create an absolute bar against ending someone's employment while they are away from work. What the law prohibits is terminating an employee because of a protected ground such as disability, or because the employer perceives the employee to have a disability that might interfere with future attendance. An employer who can demonstrate genuine, non-discriminatory reasons for dismissal—performance deficiencies, misconduct, legitimate restructuring—may lawfully terminate an employee even during a medical leave, though timing alone can invite scrutiny.
Understanding the distinction matters for owner-operators who may one day face the uncomfortable intersection of a prolonged absence and unresolved workplace issues. Under the Alberta Human Rights Act, and comparable statutes in every other province and territory, employees have the right to equal treatment in employment without discrimination based on physical or mental disability. Ontario's Human Rights Code, British Columbia's Human Rights Code, and the Canadian Human Rights Act for federally regulated employers all contain similar protections. The key question in any complaint is not simply whether the employee was on leave at the moment of termination, but whether the employer's decision was connected, even in part, to the employee's disability or perceived disability. Tribunals and courts apply a contextual analysis: they look at the stated reasons for the termination, the timing, the documentation, and whether the employer's conduct reveals assumptions about the employee's capacity to return or to perform in the future.
When an employee provides medical documentation authorizing time away from work, the employer is generally expected to respect that leave and maintain the employment relationship. However, medical leave is not a shield against accountability for issues that existed before the leave began or that arise independently of the employee's health condition. Performance problems, policy violations, or insubordination do not evaporate simply because the employee later goes off on leave. Employers retain the ability to address those matters, including through termination, provided the decision is genuinely grounded in those concerns rather than in frustration over the absence itself or speculation that the employee will never reliably return. Documenting performance issues contemporaneously and separately from any medical leave is essential. An employer who waits until an employee is on leave to suddenly compile a file of complaints will face obvious credibility problems before a human rights tribunal.
Timing, however, remains one of the most sensitive variables. Even when legitimate grounds exist, terminating an employee in the middle of a medical leave invites the inference that disability was at least part of the motivation. Tribunals have found employers liable where evidence suggested they seized on a gap in medical documentation, or used an employee's failure to attend a return-to-work meeting, as a pretext to end the relationship before another medical note could arrive. Employers should be cautious about acting hastily. If a meeting is scheduled and the employee does not appear, it is prudent to follow up in writing, inquire about the reason for the absence, and allow reasonable time for a response before concluding that the employee has abandoned the position or is otherwise subject to termination.
Dialogue is fundamental throughout any leave. The duty to accommodate is a cooperative process involving employer, employee, and, where applicable, a union. An employee is not obligated to disclose a specific diagnosis, but must provide enough information for the employer to understand the nature of any functional limitations and the expected duration of the absence. Employers, in turn, should maintain reasonable communication, request updated medical information when appropriate, and plan for reintegration. A policy requiring a meeting before an employee returns from medical leave is legitimate, but it should be applied consistently and should not be wielded as a barrier to re-entry. Employers who make return-to-work meetings unnecessarily difficult, or who draw negative inferences from an employee's inability to attend on short notice, risk the appearance of constructive dismissal or discriminatory conduct.
From the employee's perspective, cooperation is equally important. An employee who refuses to communicate, declines to provide requested medical updates, or misses scheduled meetings without explanation weakens any subsequent claim that the employer acted in bad faith. Tribunals expect both parties to engage constructively. An employee who believes they are being harassed or targeted should document interactions, keep copies of correspondence, and, if necessary, seek legal advice or file a complaint with the applicable human rights commission or tribunal.
Owner-operators should also be aware that damages in human rights proceedings can include compensation for lost wages and for injury to dignity, feelings, and self-respect. Awards vary depending on the severity of the conduct, the duration of the infringement, and the vulnerability of the complainant. An employer found to have terminated an employee partly because of perceived disability, even where performance concerns also existed, can be ordered to pay several thousand dollars or more, plus pre-judgment interest. The costs of defending a complaint, including management time and legal fees, often exceed the eventual award.
Practical steps can reduce exposure. First, address performance issues as they arise, through documented conversations and written warnings where warranted, rather than waiting until a leave complicates matters. Second, maintain consistent policies around medical documentation, return-to-work procedures, and communication during absences. Third, when contemplating termination of an employee who is on leave or has recently returned, obtain legal advice before acting. The timing alone may create a presumption of discrimination that the employer will need to rebut. Fourth, train managers to avoid comments that could be interpreted as reflecting frustration with an employee's absences or skepticism about their condition; such remarks can become damaging evidence. Fifth, if a termination is genuinely unrelated to disability, ensure the termination letter and internal documentation clearly articulate the actual reasons and avoid any reference to the leave itself as a factor.
No Canadian statute guarantees that employment will be preserved indefinitely simply because an employee is away on medical or other leave. What the law demands is that employers act on genuine, non-discriminatory grounds and that they not allow assumptions about an employee's health or future attendance to taint their decisions. When those principles are respected, termination during a leave of absence can withstand legal challenge. When they are not, the consequences can be costly and reputationally damaging for the business.
