Telling your staff that you’re selling the business is one of the hardest conversations a business owner has to have, and one of the most consequential in terms of timing. Say it too early, and you risk a confidentiality leak that damages the deal or spooks your key people. Say it too late, and employees can feel blindsided, which has its own costs.

This article separates what Ontario law actually requires from what’s simply good practice when it comes to notifying employees of a business sale.

What Ontario Law Actually Requires

There is no general statutory rule requiring a seller to notify employees, in advance, that a business sale is happening. Employees don’t have a standalone legal right to be told about a pending sale before it closes. What the law does regulate is what happens to their employment once a sale occurs — through mechanisms like continuity of service under section 9 of the Employment Standards Act, 2000 — not whether or when they’re told beforehand.

This means the timing of employee communication in a sale is driven mainly by practical and strategic considerations, not a legal notice requirement — though it’s worth confirming this against your specific circumstances, since sector-specific or contractual obligations, such as a union collective agreement, can create notice requirements that don’t apply to businesses generally.

Why Confidentiality Usually Comes First

Most business sales are kept confidential through the letter of intent stage and much of due diligence, for good reason:

This is why confidentiality agreements are typically among the first documents signed in a sale process, well before any broader employee communication is even contemplated.

When the Law Does Step In

Even though there’s no general pre-sale notice requirement, the law becomes directly relevant once staffing decisions are actually made:

A Practical Timeline for Telling Staff

  1. Letter of intent stage — typically no broad employee communication yet; only the smallest circle of key people, if any, are read in, under confidentiality.
  2. Due diligence — some additional employees may need to be involved to provide information, again typically under confidentiality obligations.
  3. Signing of the definitive agreement — momentum is now real; many sellers begin planning employee communication around this point, even if closing hasn’t happened yet.
  4. At or near closing — the most common point for a fuller announcement to staff, often coordinated jointly with the buyer.
  5. Post-closing integration — ongoing communication about what’s changing, and what isn’t, as the buyer’s plans take effect.

What to Say (and What Not to Promise)

Frequently asked questions

Do I legally have to tell employees before the sale closes?

Generally, no — there’s no standalone statutory requirement to notify employees in advance of a pending sale. Confirm this against your specific situation, particularly if a union or individual contract terms are involved.

Can I ask key employees to keep the sale confidential?

Yes, this is standard practice, typically formalized through a confidentiality agreement for anyone read in early.

What should I tell employees about their jobs if I genuinely don’t know yet?

Honesty about the uncertainty is usually better than false reassurance. You can explain the process and general timeline without promising outcomes that haven’t been decided.

Who should deliver the news — the seller, the buyer, or both?

This varies by deal, but coordinated, joint communication at or near closing is common, so employees hear a consistent message from both sides at once.
