Key takeaways
  • - [ ] Obtain any third-party consents your purchase agreement requires — landlord consent to assign a lease is the most common, but financing, licence, or contract consents may also apply.
  • - [ ] Deliver share certificates endorsed for transfer, in a share sale, or the bill of sale and asset assignments, in an asset sale.
  • - [ ] Cooperate with the post-closing working-capital adjustment process, including providing the final closing statement within the timeline your agreement sets out.

If you're selling an Ontario business, closing day is when your side of the purchase agreement's promises come due — every representation, every "deliverable" the agreement lists, and every consent you agreed to obtain. Buyers, and their lawyers, will hold the purchase price back until you've produced what you agreed to hand over.

Exactly what you need to deliver depends on whether you're selling shares or assets, but organizing this seller closing checklist by timing — what needs to happen before closing day, what happens at the closing table, and what still needs attention afterward — helps avoid a last-minute scramble.

What Sellers Often Get Wrong

Frequently asked questions

What if I can't get a required third-party consent before closing?

Talk to your lawyer well before the scheduled closing date. Options can include delaying closing, closing with a post-closing covenant to deliver the consent once obtained, or restructuring how that specific asset or contract is handled.

Do I need to keep records after the sale closes?

Generally, yes, for a period your accountant and lawyer recommend, particularly for anything that could support or defend an indemnity claim tied to your representations and warranties.

What is a bring-down certificate and why does the buyer need one from me?

It's your confirmation, signed at closing, that the representations and warranties you made in the purchase agreement are still true as of the closing date — not just when you signed the agreement weeks or months earlier. Buyers typically won't close without one.

Can I negotiate what goes on my closing deliverables list?

Yes. The purchase agreement itself defines exactly what you're obligated to deliver, and that list is negotiated, like everything else in the agreement, before it's signed, not decided on closing day.
