Rescinding a Job Offer in Ontario: What Employers Risk by Pulling Out

A hiring plan changes. The role gets cut in a reorganization, budget gets pulled, or a background check raises a concern — and the employer decides to rescind the job offer before the person's first day. It feels like nothing has really happened yet, since the person never actually started work.

Legally, that instinct can be wrong. Once an offer has been accepted, Ontario law may already treat a binding employment contract as existing — and walking away from it can carry real financial exposure, even though no work was ever performed.

This article explains when that risk arises and how employers can structure offers to manage it.

When Does a Binding Contract Exist?

Under ordinary contract principles, an employment contract can come into existence the moment an offer is accepted — it does not need to wait until the employee actually shows up for their first day. If the offer's essential terms (role, compensation, start date) were clear and the candidate accepted, a court may treat that exchange as a done deal.

That means "the person hasn't started yet" is not, by itself, a legal shield. The relevant question is whether an offer was made and accepted, not whether work has begun.

What Happens When an Employer Pulls Out

Pulling back an accepted offer before the start date is generally treated as the employer walking away from its own obligations under that contract. Depending on the facts, the rejected candidate may have a claim for damages meant to put them in the position they would have been in had the employer honoured the offer.

The size of that exposure is fact-specific — there is no fixed formula, and courts look at the whole picture: how firm the offer was, how the candidate relied on it, and what steps the candidate took (or could reasonably have taken) to find other work afterward.

Reliance Is What Raises the Stakes

The risk escalates sharply when the candidate took real, provable steps in reliance on the offer — most commonly:

• Resigning from their current job
• Turning down a competing offer
• Relocating, or signing a lease, in anticipation of the new position
• Giving formal notice to a client base or business relationships tied to their old role

An employer who rescinds an offer after a candidate has already resigned elsewhere is in a materially worse position than one who rescinds before the candidate has taken any irreversible step.

Does the ESA Apply Before the Start Date?

This is a point employers frequently get backwards. The Employment Standards Act, 2000's notice-of-termination scheme is generally built around an employment relationship that has actually begun. A rescinded offer before the start date typically doesn't fit neatly into that statutory framework the way a dismissal of an active employee would.

That doesn't mean there's no exposure — it usually just means the claim, if one arises, is analyzed as an ordinary breach-of-contract matter under common law rather than as a statutory ESA claim. The practical result can still involve meaningful damages; it simply flows from a different legal route. This is exactly the kind of nuance worth confirming with a lawyer before responding to a candidate's complaint.

How Employers Can Reduce This Risk

1. Make offers genuinely conditional where appropriate. If a background check, reference check, or professional licensing confirmation still needs to happen, say so clearly and in writing — and don't extend an unconditional-sounding offer while those steps are outstanding.
2. Put every material term in writing before the candidate acts on it. Verbal assurances create the same acceptance risk with far less clarity about what was actually promised.
3. Move quickly on internal decisions. The longer a signed offer sits before a reorganization or budget review catches up to it, the more likely the candidate has already relied on it.
4. Get legal input before withdrawing a signed offer, especially if the candidate has indicated they've already resigned from another position or turned down a competing offer.
5. If the situation changes, communicate promptly and, where appropriate, discuss a fair resolution rather than simply going silent — this can meaningfully affect how a dispute later plays out.
