In a growing number of Ontario mid-market business sales, the seller's promise to stand behind its representations is being backed — or in some cases replaced — by an insurance policy rather than the seller's own pocket. Representations and warranties insurance, usually shortened to R&W insurance, pays out for losses caused by a breach of the seller's representations, instead of (or in addition to) the buyer chasing the seller directly.

It is not standard on every deal, and it is not a substitute for careful due diligence. But where it is used, it changes how the whole indemnity structure of the deal gets negotiated.

What R&W Insurance Covers

An R&W insurance policy responds to financial losses arising from a breach of the representations and warranties made in the purchase agreement — the same representations that would otherwise be backed by the seller's indemnity obligation. If a representation about the business turns out to have been inaccurate and causes the buyer a loss, the policy (rather than, or alongside, the seller) pays the claim, subject to the policy's own terms, exclusions, and retention amount.

The policy is underwritten based on the specific representations in that deal's purchase agreement and the due diligence conducted — insurers typically review the disclosure schedule, the diligence reports, and the drafting of each representation closely before pricing and issuing a policy, which is one reason R&W insurance adds its own timeline and cost to a transaction rather than being a quick add-on.

Buy-side policies have become the more typical structure because they let the buyer pursue a well-capitalized insurer directly, rather than relying on the seller (who, after closing, may no longer have significant assets tied to the business) to make good on an indemnity claim years later.

When R&W Insurance Shows Up in Ontario Deals

R&W insurance tends to appear on larger, more sophisticated transactions rather than small, owner-operated business sales — the underwriting process, premium, and policy minimums generally make it uneconomical for very small deals. It is more commonly seen where:

Whether R&W insurance makes economic sense for a given transaction depends on the deal's size, the insurance market's appetite for the industry involved, and the cost of the policy relative to the risk it is replacing — this is a discussion for your lawyer and an insurance broker together, not a default assumption either way.

How It Changes Indemnity Negotiations

Where R&W insurance is in play, several of the indemnity provisions that would otherwise be fiercely negotiated between buyer and seller shift instead into negotiations with the insurer:

The result is often a smoother negotiation on the buyer-seller side, because much of the risk allocation debate is redirected toward the insurer's underwriting requirements instead.

What R&W Insurance Does Not Cover

Frequently asked questions

Is R&W insurance available for every business sale in Ontario?

No. Insurers generally set minimum deal-size thresholds and evaluate the industry, the quality of due diligence conducted, and the specific representations before agreeing to underwrite a policy. Smaller, straightforward business sales may find it unavailable or uneconomical compared with a traditional seller indemnity.

Does R&W insurance replace the need for due diligence?

No — if anything, it raises the bar. Insurers price and scope their policies based on the buyer's due diligence, and issues that a more thorough investigation would have caught are typically excluded from coverage as "known issues."

Who pays for the policy?

This is negotiated between the parties and can be allocated to either side, split, or built into the overall deal economics. There is no fixed market convention that fits every transaction.

Does using R&W insurance mean the seller has no ongoing liability at all?

Not necessarily. Even with a buy-side policy, sellers commonly retain some liability — often for fraud, for certain fundamental representations, or up to a reduced cap — depending on how the specific policy and purchase agreement are drafted together.
