7 Tax and Ownership Rules Americans Miss When Buying Canadian Real Estate
A U.S. citizen closing on a condo in Vancouver last fall discovered the hard way that her $85,000 gain on sale was tax-free in Canada under the principal residence exemption, but fully taxable to the IRS above the $250,000 single-filer threshold. She'd structured the purchase assuming Canadian rules applied on both sides of the border. They don't.
Here's what Americans consistently miss when buying residential property in Canada, written for those navigating the mechanics after 2023.
1. You file the Underused Housing Tax return even if you owe nothing.
Non-resident, non-Canadian owners of residential property must file an annual UHT return by April 30, even when they qualify for an exemption. The federal tax is 1% of the property's assessed value. Miss the filing and you pay the 1% plus penalties, regardless of whether you actually used the property all year. The CRA does not send reminders.
2. The foreign buyer ban is still active through December 2026.
Most Americans who are not Canadian permanent residents or work permit holders cannot buy residential property in Canada until January 1, 2027 under the Prohibition on the Purchase of Residential Property by Non-Canadians Act. The exception: recreational properties (cottages, cabins) in census agglomerations under 10,000 people, and certain rural land. Urban condos and single-family homes in Toronto, Vancouver, Calgary, and Montreal remain off-limits.
3. Provincial foreign buyer taxes stack on top of federal rules.
Ontario charges a 25% Non-Resident Speculation Tax on the purchase price in the Greater Golden Horseshoe. British Columbia has a similar tax in Metro Vancouver and other regions. These are separate from the federal UHT and apply at closing, not annually. Becoming a permanent resident within a certain window (typically four years in Ontario) triggers a rebate, but you pay upfront.
4. Rental income gets hit with 25% withholding unless you elect otherwise.
The default Canadian tax on gross rental income for non-residents is 25%, withheld at source. Section 216 of the Income Tax Act allows you to be taxed on net rental income instead (actual rate depends on deductions and brackets), but you must file an election and annual return. Most Americans renting out their Canadian property find the 25% gross withholding to be a cash-flow problem in year one before they file for the refund.
5. Mortgage terms reset every five years, not thirty.
Canadian mortgages are structured with short terms (commonly five years) and long amortizations (25-30 years). Your interest rate resets at the end of each term based on prevailing rates. If you financed at 2.5% in 2021 and rates are 5.5% in 2026, your payment jumps. Americans accustomed to 30-year fixed loans underestimate this exposure.
6. The principal residence exemption does not shelter U.S. tax above the exclusion cap.
Canada allows tax-free gains on a principal residence for Canadian tax residents. The IRS caps the exclusion at $250,000 for single filers, $500,000 for married filing jointly. A couple in Toronto who bought for $800,000 in 2019 and sold for $1.4 million in 2024 pays zero Canadian tax but owes U.S. capital gains tax on the $100,000 above the $500,000 exclusion. The Canada-U.S. Tax Treaty prevents double taxation but does not eliminate the U.S. liability.
7. Selling triggers a 25% withholding on the gross price unless you get a clearance certificate.
When a non-resident sells Canadian property, the CRA withholds 25% of the gross sale price unless the seller applies for and receives a Certificate of Compliance before closing. On a $600,000 sale, that's $150,000 held until you file a return and prove the actual tax owed. The certificate application takes 4-12 weeks. Most buyers' lawyers will not release funds without it.
The one that costs the most is #6. It surfaces years later, often without warning.
