Selling Ontario Property as a Non-Resident: Withholding Tax and Clearance Certificates

If you live outside Canada but own property in Ontario — whether it is a family home, a rental unit, or a condo you kept after moving abroad — selling it triggers Canadian tax obligations that many sellers are caught off guard by. The key mechanism is a mandatory withholding of a portion of the sale proceeds by the buyer, which is held pending Canada Revenue Agency (CRA) approval. Without proper planning, you may find your closing proceeds tied up for months.

This article explains the withholding rules that apply to non-resident sellers of Ontario real estate, how to obtain a CRA clearance certificate to release the holdback, and what steps to take well before your closing date.

Tax rules change. Withholding rates, filing deadlines, and CRA procedures referenced in this article are described as of writing. Always verify current rules with the CRA or a qualified Canadian tax advisor before closing.

Why Non-Resident Sellers Face Withholding

Canada taxes non-residents on gains they earn from disposing of "taxable Canadian property," which includes real estate located in Canada. Because the seller (a non-resident) may have no ongoing connection to Canada after closing, the Income Tax Act requires the buyer to withhold a prescribed portion of the purchase price and remit it to the CRA. This is the mechanism commonly referred to in the context of "section 116" — the part of the Income Tax Act that governs this process.

The withholding is not the final tax — it is essentially a deposit held by the government until the non-resident files a Canadian tax return and pays any actual capital gains tax owed. Once CRA confirms the tax has been paid or secured, it issues a clearance certificate authorizing release of the holdback.

How Much Is Withheld?

The withholding percentage depends on the type of property and whether it was depreciable property (like a rental building). As of writing, the withholding for non-depreciable property (e.g., a personal residence or bare land) is a percentage of the gross sale price, not the gain. For depreciable property (i.e., property used to earn rental or business income), a higher percentage may apply.

These rates have not changed recently but you should confirm the current rates with the CRA or your tax advisor before assuming they still apply, as the Income Tax Act and CRA guidance can be updated.

Because the withholding is calculated on the gross price (not the profit), the amount held can be very large relative to the actual tax owing — especially if you have a large mortgage or your cost basis is high.

The Clearance Certificate Process

Step 1: Notify the CRA Before or Shortly After Closing

As a non-resident seller, you are required to notify the CRA of the disposition and apply for a clearance certificate. There is a deadline for this notice — as of writing, you must generally notify the CRA on or before a prescribed date related to the closing date. Missing the deadline can result in penalties.

The application requires you to provide the CRA with information about the property, the sale price, your adjusted cost base (ACB — roughly, what you originally paid plus certain capital improvements), and your identity.

Step 2: CRA Reviews and Issues the Certificate

The CRA reviews your application, calculates the estimated capital gain, and determines how much tax is expected to be owed. It will either:

• Issue a certificate once sufficient tax is paid or security is provided
• Request additional information or security

The processing time for clearance certificates has historically been lengthy — often several months. This is the most common source of friction on closings involving non-resident sellers. Do not wait until after you accept an offer to start this process. Begin the CRA notification and tax professional engagement well in advance.

Step 3: Release of Holdback

Once your lawyer receives the clearance certificate, they can release the withheld amount from closing proceeds to you (less any actual tax remitted to CRA). If the clearance certificate arrives after closing, your lawyer holds the withheld amount in trust until the certificate is issued.

What Happens if a Buyer Does Not Withhold?

The buyer's lawyer is responsible for ensuring the holdback is in place at closing. If the buyer's lawyer fails to withhold and remit, the buyer can be held personally liable for the non-resident's Canadian tax obligation. This is a real risk that well-advised buyers and their lawyers take seriously, and it is why non-resident sellers sometimes face requests for detailed immigration status documentation before offers are accepted.

Principal Residence Exemption for Non-Residents

If the Ontario property was your principal residence for some or all of the years you owned it, you may be entitled to a principal residence exemption that reduces or eliminates the capital gain. However, only years during which you were a Canadian resident for tax purposes and designated the property as your principal residence qualify for the exemption. If you moved abroad mid-ownership, only the years of Canadian residency (assuming you designated the property) would be sheltered.

The interaction between the principal residence exemption and the non-resident withholding rules is complex and tax-specific. A Canadian tax accountant or tax lawyer should calculate your actual exposure before you apply for the clearance certificate.
