Can a seller introduce new conditions after signing a Letter of Intent in Canadian M&A?

Yes. In Canadian lower-middle-market M&A — deals typically ranging from $5 million to $50 million — a Letter of Intent (LOI) is mostly non-binding on core commercial terms. It locks in exclusivity (typically 30–90 days), signals mutual commitment and sets the stage for due diligence, but it functions more as a flexible blueprint than an ironclad contract. This means sellers can introduce new conditions after the LOI — a lease extension, key-employee incentives, or fresh environmental warranties — without automatically derailing the deal. The key is presenting the condition as a value-adding refinement, not a roadblock.

Which LOI terms are binding and which are not?

LOIs generally bind only on procedural “sideshow” provisions: the no-shop/exclusivity covenant, confidentiality obligations and (where included) break-fee and governing-law clauses. The substantive commercial terms — conditions precedent, final price adjustments, reps and warranties — remain open until the Share Purchase Agreement (SPA) is executed. Canadian advisory benchmarking suggests 70–80% of lower-middle-market LOIs evolve materially during the diligence window, as that process reveals supply chain vulnerabilities, regulatory issues or other facts that demand adjustments.

Why must sellers handle post-LOI conditions carefully?

These transactions are relationship-driven — trust underpins 70–80% of them. In the current environment of inflation pressure and U.S. tariff uncertainty, buyers are more risk-averse and more attuned to surprises. A condition sprung late and without context can breed doubt or kill the deal. Canadian sellers also operate under a duty of good faith in contractual performance (recognized by the Supreme Court of Canada in Bhasin v. Hrynew, 2014) and provincial contract law, which reinforces the expectation of honest, non-opportunistic dealing.

How should a seller propose a new condition without triggering pushback?

Timing and tone are decisive. Best practice:
1. Launch early — raise the condition in weeks 1–4 of exclusivity, not on the eve of signing the SPA
2. Use relational channels first — introduce the idea informally through the established relationship (or via your advisor) before formalizing it in a written markup
3. Frame it as a mutual safeguard — explain how the condition de-risks the deal for the buyer (e.g., “This lease reset secures your operations for two additional years, based on current market data”)
4. Anchor in evidence — support the condition with diligence findings, third-party data or peer benchmarks so it reads as a refinement, not a demand
5. Formalize once aligned — capture the agreed condition in the SPA markup after the buyer has signaled acceptance in principle

What are the main risks, and how do sellers avoid them?

- Perceived bad faith: introducing a price-changing condition late looks opportunistic; probe price-sensitive issues before the LOI where possible
- Exclusivity jams: a major new condition during exclusivity can stall the only active negotiation; raise material items early so there is time to resolve them
- Erosion of trust: surprises damage the relationship that drives the deal; communicate transparently and consistently
- Walk-away risk: a buyer who feels ambushed may exit; keep the framing collaborative and evidence-based

What practical tips improve success in the lower middle market?

- Harness networks: with a large share of Canadian deals originating from introductions, lean on pre-LOI rapport to soft-land the proposal
- Trend-spot: tariff uncertainty is increasing the relevance of supply chain conditions — benchmark against peers to show the condition is market-standard
- Know when to fold: for price-altering issues, surface them before the LOI to avoid exclusivity conflicts later
