Constructive dismissal (Canada)

The doctrine in outline

Two routes: a single unilateral change that substantially alters an essential term (compensation, role, location, hours), or a course of conduct showing the employer no longer intends to be bound by the contract, which is where poisoned-workplace claims live. The employee must treat the change as ending the employment within a reasonable time (staying silently for a year usually means acceptance), and the remedy is the same as wrongful dismissal: reasonable notice damages.

The 2025-26 development: return-to-office as dismissal

Canadian courts have begun holding that revoking entrenched remote-work arrangements can be constructive dismissal. In 2025, an Alberta decision found a rigid return-to-office mandate imposed on a long-term remote employee was constructive dismissal, and British Columbia's Court of Appeal upheld 19 months' damages on similar facts. Where working from home has hardened into a term of the contract, unilaterally recalling the employee is a fundamental change like any other, requiring notice, fresh consideration or genuine agreement. RTO mandates are therefore simultaneously an attrition-risk decision and a legal-exposure decision, and pretending they are only a policy memo prices both wrong.

Changing terms without triggering it

Lawful change management is procedural: reserve flexibility expressly in contracts, give reasonable advance notice of significant changes (effectively working notice of the new terms), obtain agreement supported by fresh consideration where the change is material, and phase what can be phased. Most constructive dismissal claims are avoidable process failures, the employment-law cousin of every restructure that announced first and consulted afterwards.
