Can I change my closing date after signing an agreement in Ontario?

4 min read Updated September 2026 Written by Chetanaya Gupta, Ontario lawyer

The short version

Yes, but only if both sides agree in writing through a formal amendment to your agreement of purchase and sale. Neither side can move the date alone, and if the other side won't agree, your options narrow to closing as scheduled or treating the delay as a default.

01

How do I actually change a closing date?

Both the buyer and seller have to sign a written amendment to the agreement of purchase and sale. It's usually a short document: the new date, and anything that changes because of it, like adjustments for extra days of interest. Your lawyer or agent prepares it. A verbal agreement to push the date isn't enforceable on its own, so get it in writing before you rely on it.

02

Why would someone need to move a closing date?

Common reasons include a mortgage approval running behind, a chain of purchases and sales that don't quite line up, a title issue that needs more time, or a moving delay on either side. Sometimes it's requested weeks ahead, sometimes in the final days before closing.

03

What if the other side won't agree to a new date?

Then the original date stands. If you can't close on it, you're in default, which can mean losing your deposit as a buyer, or facing a damages claim, as either party. See our pages on what happens if a buyer can't close or on selling a home for what that looks like from each side. Talk to your lawyer before the closing date arrives, since there's more room to negotiate before a default happens.

04

What is bridge financing and how does it help?

Bridge financing is a short-term loan covering the gap when your sale and purchase don't close on the same day, usually when your sale closes after your purchase. It's secured against the equity in the home you're selling and is normally repaid the day your sale closes. Most lenders want firm, unconditional agreements on both properties before approving one. It solves a timing gap between your two closings, but it doesn't change what date you and the other side agreed to.

05

What if I'm buying and selling at the same time?

Try to build in a few days of buffer between your sale and purchase closings, rather than same-day closings, which leave no room for a small delay. If you're selling first, ask about bridge financing early, since your lender needs both agreements finalized before approving it. Your lawyer coordinates timing on both files, but the actual dates still come down to what's written in each agreement.

What to do next

Where to go from here

  1. Get any closing date change in writing as a signed amendment, not a verbal understanding.
  2. Tell your lawyer as soon as a delay looks likely, ideally weeks before closing, not days.
  3. Ask about bridge financing early if you're buying and selling around the same time.
Quick questions

People also ask

Can I just email the other side to agree on a new date?

No. It needs a signed written amendment to be enforceable, not an informal email exchange.

Does moving the closing date change my mortgage?

It can. Tell your lender as soon as a new date is set, since your mortgage instructions may need updating.

What if only one side wants to delay closing?

The other side has to agree, or the original date stays binding, with default consequences if it's missed.

Is bridge financing expensive?

It costs more than a regular mortgage rate, since it's short-term and interest-only, but it's often cheaper than the cost of a rushed sale.
