Key Employee Retention as a Closing Condition in an Ontario Business Sale

A business is often worth more than its assets and contracts — it's worth what its people know and who they know. When a buyer is purchasing an Ontario business built around a handful of key employees, the purchase agreement will often include something the general public rarely hears about: a key employee retention closing condition, requiring specific staff to agree to stay on, or to sign new terms, before the deal can close.

This condition exists because a buyer's valuation of the business assumes those people will still be there on day one after closing. If the general manager, the top salesperson, or the founder-turned-employee walks the moment the sale is announced, the buyer may be paying full price for a business that has quietly lost some of its value.

This article explains why buyers ask for this condition, what it typically requires, and how it interacts with Ontario employment law — including the narrow rules around non-compete agreements.

Why Buyers Build This Into the Deal

Unlike most closing conditions, which confirm facts (no new lawsuits, consents received, representations still true), a key employee retention condition is about locking in future behaviour — specifically, that named individuals will still be working for the business after closing, on agreed terms.

This matters most where:

1. The business depends heavily on one or a few people's relationships, expertise, or reputation.
2. The seller, or the seller's principal, is expected to stay on temporarily to help transition the business.
3. Employees hold institutional knowledge — supplier pricing, client history, unwritten processes — that isn't captured anywhere else.

What the Condition Typically Requires

A key employee retention condition can take a few different forms, often combined:

• Signed employment agreements with the purchaser, on new or updated terms, in place before or at closing.
• Confirmation letters from named employees indicating an intention to continue with the business.
• A transition or consulting agreement with a departing owner who won't stay on as a regular employee but agrees to be available for a defined handover period.
• Non-solicitation and confidentiality agreements, protecting the buyer from a key employee later poaching clients or staff even if that employee eventually leaves.

The Non-Compete Complication

Buyers sometimes want more than a promise to stay — they want assurance that a key employee, particularly a departing owner, won't simply leave later and open a competing business down the street. Since October 25, 2021, Ontario's Employment Standards Act generally prohibits employers from entering non-compete agreements with employees. There are two recognized exceptions:

This means a non-compete can generally still be used on a departing owner who is staying on as an employee after the sale, but the same tool is not automatically available for every "key employee" a buyer wants to retain. A manager who isn't an executive and isn't a selling owner, for example, may not fall within either exception — which is exactly why a blanket assumption that everyone can simply sign a non-compete doesn't hold up.

Non-solicitation and confidentiality agreements are a separate category and are not affected by this restriction — they remain generally enforceable, subject to ordinary reasonableness limits, which is why they tend to do more of the practical work in retaining a business's client relationships after closing.

Employment Continuity vs Retention — Two Different Questions

It's worth distinguishing statutory employment continuity from a negotiated retention condition, because they answer different questions:

• ESA continuity of employment deals with whether an employee's prior service counts toward entitlements like vacation or notice after a sale — it applies where a going-concern business is sold and the purchaser hires the seller's employees, but a purchaser has no statutory obligation to hire any particular employee in an asset sale.
• A retention condition is a negotiated deal term about whether specific, named individuals agree to particular terms before the deal is allowed to close at all — a business decision layered on top of, not a substitute for, the underlying employment law.

Steps for Structuring a Retention Condition

• [ ] Identify which roles are genuinely critical to the business's value, rather than defaulting to "everyone."
• [ ] Decide early whether new employment terms, a consulting arrangement, or a simple confirmation letter is the right tool for each person.
• [ ] Confirm whether a non-compete is legally available for that individual under the business-sale or executive exception, or whether non-solicitation and confidentiality terms are the realistic option instead.
• [ ] Build a clear closing condition into the purchase agreement, rather than relying on informal assurances from the seller.
• [ ] Address what happens if a key employee refuses to sign — whether that's a walk-away right, a price adjustment, or something else entirely.
