✅Quick answer. The deadline on a severance offer is almost always a negotiating tactic, not a legal rule. Nothing about your rights expires when the clock runs out: your ESA minimum termination and severance pay are owed regardless, and you generally have up to two years to bring a wrongful dismissal claim for your full common-law entitlement. Employers rarely actually withdraw an offer when you ask for reasonable time to get advice. The real risk is not missing the deadline, it is signing too fast and giving up money you were owed.
A short deadline is designed to make you anxious and quick to sign. Understanding what genuinely expires, and what does not, takes the pressure out of the moment.
Is the deadline even real?
Usually not in the way it is presented. Employers set a date to discourage you from getting advice, because advice tends to reveal that the offer is low. In practice, asking for reasonable time to review an offer is normal and expected, and offers are rarely pulled for it. Even if an employer withdrew a discretionary top-up, your statutory minimums remain payable, and your right to pursue common-law notice does not vanish on their date. Courts do not punish you for taking time to get advice.
What you actually risk by signing fast
The danger runs the other way. Signing the release quickly can lock you into the ESA floor and give up the common-law amount, which is usually much larger. Here is the gap you may be forfeiting:
Know your number before the deadline
Before you respond to any deadline, get a free estimate of your severance range and compare it to the offer. If there is a gap, that is your reason to take the time.
What should you do when there is a deadline?
- 1.Do not let the date rush you into signing; ask for reasonable time to review.
- 2.Separate your guaranteed ESA minimum from the negotiable amount on top.
- 3.Estimate your common-law range and compare it to the offer.
- 4.Get advice before the deadline, and do not sign the release until you know your number.
The deadline is leverage, not law. See should you sign the severance offer, what 'without prejudice' means, and severance pay in Ontario, and get a severance review before you respond.
Frequently asked questions
Does a severance offer really expire in Ontario?
The signing deadline is a negotiating tactic, not a legal rule. Your ESA minimums are owed regardless, offers are rarely actually withdrawn when you ask for time, and you generally have up to two years to pursue your full common-law entitlement.
What happens if I miss the deadline to sign?
Usually nothing to your core rights. Your statutory minimum pay is still owed, and your right to claim common-law notice does not disappear on the employer's date. At most you might lose a discretionary top-up, which advice can often recover anyway.
Can my employer withdraw the offer if I ask for time?
It is rare. Asking for reasonable time to review is normal and expected, and courts do not penalize you for it. Even if a discretionary amount were pulled, your statutory minimums and your common-law claim remain.
How long do I actually have to act?
Generally up to two years to start a wrongful dismissal claim in Ontario. You should not sign under pressure, but you also should not let the deadline to get advice slip. A quick review tells you whether the offer is fair.
