A purchase agreement doesn't just say what the seller promised about the business — it also says how long the buyer has to do something about it if a promise turns out to be false. That window is the survival period, and it's one of the most negotiated (and most misunderstood) pieces of any Ontario business purchase agreement.

Get the survival period wrong — either as buyer or seller — and you can end up either unable to pursue a legitimate claim, or exposed to one indefinitely.

What a Survival Period Actually Does

Every representation and warranty in a purchase agreement is, legally, a snapshot statement made as of closing (or another specified date). The survival period sets the deadline for the buyer to identify a problem with that statement and bring it forward as a claim. Once the survival period for a particular representation expires, a claim based on it is generally no longer available under the agreement — even if the underlying issue is genuine.

This isn't set by statute. There's no fixed legal rule dictating how long a survival period must be; it's a negotiated contract term, and the length varies deal by deal based on the parties' relative leverage, the nature of the business, and what's being represented.

Why Different Representations Get Different Treatment

Not every representation in the agreement is treated the same way. Purchase agreements commonly sort representations into categories, each with its own survival logic:

CategoryTypical Reasoning
General / business representationsCover day-to-day matters — contracts, employees, operations. Problems here tend to surface relatively soon after closing, so parties often negotiate a defined window tied to how quickly issues in that area would reasonably be discovered.
Fundamental representationsCover the deal's basic building blocks — who owns the shares or assets, the seller's authority to sell, and similar foundational matters. Because a problem here undermines the whole transaction, these are often treated as surviving for a much longer period, sometimes without a defined end date at all.
Tax representationsTax issues can take longer to surface, since they depend on when a tax authority might reassess a prior period. These are often tied to the relevant reassessment period rather than a fixed number pulled from nowhere.

There's no universal formula for exactly how long each category runs — that's negotiated case by case — but this three-way split (general, fundamental, tax) is the standard architecture most Ontario purchase agreements use.

What Happens When a Survival Period Expires

Once the clock runs out on a particular representation:

This is exactly why identifying a potential problem quickly, and getting legal advice about which representation it falls under, matters so much. A claim that would have been valid on day one of the survival period can become worthless if it's only raised after the window closes.

Negotiating Survival Periods

Frequently asked questions

Is there a legal minimum or maximum survival period in Ontario?

No. Survival periods are a matter of contract, not statute — the parties negotiate whatever length they agree to, subject to the general principle that the terms need to be clear and workable. There's no default period that applies if the agreement is silent, which is exactly why it needs to be addressed explicitly.

What if the purchase agreement doesn't mention survival periods at all?

This creates real uncertainty about how long representations remain enforceable, and can leave both sides guessing. It's a gap worth catching and fixing before signing, not after a dispute arises.

Do fundamental representations really never expire?

Not necessarily "never" — but they're commonly negotiated to survive much longer than general representations, sometimes without a stated end date, precisely because they go to the core validity of the transaction itself. The exact treatment still depends on what your specific agreement says.

Can the survival period be extended after the agreement is signed?

Generally only if both parties agree to amend the contract. A survival period isn't something one side can unilaterally extend just because they discover a problem close to the deadline.
