Can an Employer Rescind a Job Offer in Canada?

Can an employer legally back out after I’ve accepted?

Usually yes, an employer can withdraw an accepted offer, but doing so is treated in law as ending an employment relationship, not simply cancelling a proposal. Once an offer of employment has been accepted, a contract exists. Canadian common law implies a term into that contract that neither party will end the relationship without cause except on reasonable notice (“reasonable notice” meaning a period of working notice or equivalent pay that lets the other side adjust). This implied term applies in Ontario, Alberta, and federally regulated workplaces alike. Rescinding the offer is generally treated as terminating employment, which means the employer may owe reasonable notice or pay in lieu, even though the person never showed up for a single day of work.

This matters because it separates two very different legal pictures: an offer that is withdrawn before anyone accepts it (ordinary contract negotiation, generally free to walk away from) versus an offer that is withdrawn after acceptance (a contract exists, and ending it has legal consequences).

Why statutory minimum notice often doesn’t apply yet

Statutory notice rules (the minimums set by employment standards legislation, as opposed to the common-law notice discussed above) frequently don’t apply to a rescinded offer, because most of them only start counting once the employee has worked for a period of time. That gap is exactly where common-law notice can still bite.

Exceptions and conditions that change the answer

A few facts can shift whether, and how much, an employer owes:

• Fixed-term or task-based hiring (Ontario): Employees hired to work until the expiry of a definite term, or until completion of a specific task, are exempt from the ESA’s notice-of-termination and termination-pay requirements under O Reg 288/01. This changes the statutory analysis for that kind of hire.
• Whether the “employment relationship” had already started (Ontario): Under the ESA, a period of employment can include time when the employee wasn’t actively working but the employment relationship still existed. This is relevant to arguments about whether time before a start date counts toward entitlements.
• Alberta’s treatment of notice as contractual, not just damages: Alberta case law (Styles v Alberta Investment Management Corporation) treats common-law pay in lieu of notice as a contractual entitlement rather than damages for breach of contract, a distinction specific to how Alberta courts frame the claim.
• No statutory cap on common-law exposure: In Alberta, anything above the Code’s statutory minimum is common law only, meaning there’s no legislated ceiling limiting what a court might order.

What you can do next

Because this sits at the intersection of contract law and employment standards legislation, the options available depend on which piece of the claim is at issue:

• Statutory notice or termination pay: If the statutory threshold (three months of continuous employment, in Ontario and federally) has been met, a complaint can generally be brought to the relevant employment standards body, Ontario’s Ministry of Labour, Immigration, Training and Skills Development, or, for federally regulated employers, the federal labour program.
• Common-law reasonable notice: Where the claim is for notice or pay in lieu beyond (or outside) the statutory minimums, this is a civil claim, typically pursued through a demand letter or a court action, not a statutory complaint process.
• Reviewing the offer letter itself: Whether an offer contained conditions (such as satisfactory reference checks) can affect whether withdrawing it is treated as a lawful condition failing, versus an unconditional rescission of a binding acceptance.
