Capital Gains Tax on Foreign Property: The Canadian Seller's Complete Guide

How Capital Gains Work for Canadian Foreign Property Sellers

Canada taxes its residents on their worldwide income — and capital gains from selling property anywhere on earth are included. When you sell foreign real estate, the gain is calculated in Canadian dollars as the difference between your proceeds (sale price in CAD) and your Adjusted Cost Base (purchase price plus allowable costs, in CAD). Fifty percent of that net gain is then added to your taxable income for the year. If you are in the top marginal bracket (~53% in most provinces), the effective capital gains tax rate on a foreign property sale is approximately 26–27% of the net gain — for gains up to $250,000.

The process works in three steps. First, you determine your Adjusted Cost Base (ACB) — the total of what you paid to acquire the property in CAD, including purchase price, closing costs, and subsequent capital improvements. Second, you determine your proceeds of disposition — what you received on the sale in CAD, less allowable selling costs such as real estate commissions and legal fees. Third, you calculate the gain (proceeds minus ACB), apply the inclusion rate (50% or 66.7%), and add the taxable portion to your income for the year.

The complicating layer for foreign property is that this entire calculation must be done in Canadian dollars using exchange rates that differ at purchase and at sale. A property that shows a gain in USD may show a larger gain — or even a loss — when converted to CAD, depending on how the CAD/USD rate moved over the holding period. This currency conversion dimension is explained in detail in the next section.

On top of Canadian tax, most countries where property is physically located also impose capital gains tax on the sale. You face potential dual taxation on the same gain. The mechanism that prevents you from paying tax on 100% of the gain twice is the Foreign Tax Credit (Form T2209), which credits the foreign tax paid against your Canadian tax on the same income. But the credit is capped at your Canadian tax amount — if you paid more tax abroad than you owe in Canada on the same gain, the excess foreign tax is permanently lost.

The full capital gains calculation is reported on Schedule 3 of your T1 General return, filed by April 30 of the year following the sale. If you also paid foreign capital gains tax, the T2209 credit is calculated and claimed on the same return. For most straightforward foreign property sales, a cross-border CPA can prepare the complete filing in a few hours — the complexity lies in the record-keeping you need to hand them, not the forms themselves.

The Currency Conversion Trap

The single most misunderstood aspect of Canadian capital gains tax on foreign property is the exchange rate timing. The rule is precise: you convert the purchase price to CAD using the exchange rate on the date of purchase, and you convert the sale price to CAD using the exchange rate on the date of sale. These are almost always different rates — and the difference can be dramatic over a 5–15 year holding period.

Consider a straightforward illustration. Suppose you bought a Playa del Carmen condo in 2016 for $200,000 USD. The CAD/USD rate at purchase was 0.77 (meaning 1 CAD = 0.77 USD, or $1 USD = $1.30 CAD). Your ACB is $200,000 ÷ 0.77 = $259,740 CAD. In 2026 you sell for $280,000 USD. The CAD/USD rate has shifted to 0.72. Your proceeds are $280,000 ÷ 0.72 = $388,889 CAD. Your capital gain in CAD is $388,889 − $259,740 = $129,149. Your taxable income addition at 50% inclusion = $64,575.

Notice something: the CAD gain ($129,149) is substantially larger than the USD gain ($80,000 USD × 1.39 CAD = $111,200 at current rates). The weakened CAD inflated your apparent gain. Had the CAD strengthened instead — from 0.77 to 0.85 — the calculation would have worked in reverse, reducing your CAD-denominated gain. Currency movement is a real variable in your after-tax return from foreign real estate, and it is one that most buyers never model when making the initial purchase decision.

What exchange rate to use: CRA accepts the Bank of Canada noon spot rate on the transaction date for individual transactions. For the purchase price, use the rate on your closing date. For the sale price, use the rate on your closing date. The Bank of Canada publishes daily rates going back to 1990 at bankofcanada.ca — you can look up the exact rate for any past date. If you cannot locate the exact date (for example, you lost closing documents from 2008), CRA will accept a reasonable approximation: the annual average rate for the year is acceptable for moderate-value transactions, but the transaction-date rate is required for large amounts. For properties purchased using a wire transfer, your bank statement shows the exact CAD amount debited — that is also acceptable documentation.

Selling costs in foreign currency:Real estate commissions, notary fees, and other selling costs also reduce your proceeds — and they must be converted to CAD at the rate on the date they were paid. A 4% commission on a $350,000 USD sale ($14,000 USD) paid on the closing date must be converted at that day's rate, not an approximation. Track every closing cost with date and foreign currency amount.

Calculating Your Adjusted Cost Base (ACB)

Your Adjusted Cost Base is everything you paid to acquire and improve the property, converted to CAD at the transaction date for each item. The higher your ACB, the lower your capital gain. Many sellers under-report their ACB because they only include the purchase price and forget the additional costs — which in Mexico alone can add 6–9% to closing costs, potentially $20,000–$35,000 CAD on a $300,000 USD condo.

What goes into your ACB:

• Purchase price — the amount you paid to the seller in CAD at the closing-date exchange rate
• Notary / closing fees — the notario's fee in Mexico, solicitor fees in Portugal or the DR, each converted at the rate on the date paid
• Transfer taxes — Mexico's ISAI (~2% of assessed value), Portugal's IMT (1–8%), Dominican Republic's 3% transfer tax — these are acquisition costs, not income taxes, so they add to ACB rather than qualifying for the FTC
• Real estate agent commission at purchase — if you paid a buyer's agent commission (less common abroad, but it occurs)
• Legal due diligence costs — title search, survey, escrow fees paid at acquisition
• Capital improvements after purchase — new rooms, pools, structural additions. Each improvement is added at the CAD cost on the date of payment. Routine repairs and maintenance do not qualify
• Fideicomiso setup fees — the one-time bank trust establishment fee in Mexico is a cost of acquiring the property and is part of your ACB

What does NOT go into your ACB: annual carrying costs (property taxes, fideicomiso annual fees, insurance, utilities, property management fees) are operating expenses, not capital costs. They may be deductible against rental income during ownership on Form T776, but they do not add to ACB and cannot reduce your eventual capital gain.

Record-keeping discipline: Keep a running ACB spreadsheet from the day you purchase. Column A: item description. Column B: date. Column C: foreign currency amount. Column D: Bank of Canada rate that day. Column E: CAD equivalent (C ÷ D). Sum Column E = your current ACB. Update it each time you make a capital improvement. If you ever face a CRA audit, this spreadsheet — backed by invoices and bank statements — is the foundation of your defense.

If you have claimed Capital Cost Allowance (CCA / depreciation) on the property during its rental years, CCA reduces your ACB and will be recaptured as ordinary income (not capital gains) in the year of sale. CCA recapture is often more expensive than the tax saving from the original deduction — most foreign rental property owners are advised not to claim CCA.

Country-by-Country Capital Gains Tax Rates

Foreign capital gains tax rates vary widely. Some countries — like Belize — charge nothing. Others — like Portugal for non-residents — charge 28% flat on the full gain. Understanding the destination country's rate before you sell is critical, because it determines both your foreign tax bill and the size of the T2209 credit available to offset your Canadian liability.

A few destination-specific points worth elaborating:

Mexico

When a Canadian sells Mexican property, the notario (notary public) is legally required to withhold ISR (Mexican income tax on gains) at closing. The default rate is 25% of the gross sale price — no deduction for your purchase cost. However, non-residents can elect an alternative calculation of approximately 30% of the net gain (proceeds minus allowed deductions) if they appoint a Mexican tax representative. For properties bought at a significant discount to current value, the net-gain election is typically far lower. For a condo bought at $200,000 USD and sold at $350,000, the 25% gross calculation = $87,500 USD; the ~30% net calculation (on $150,000 USD gain) = $45,000 USD. Always model both options before closing.

The ISR withheld by the notary is the Mexican tax you claim on T2209 against your Canadian liability. Request a formal receipt (constancia de retención) from the notary for your Canadian tax records.

Portugal

For non-residents selling Portuguese property, Portugal taxes 100% of the capital gain at a flat 28% rate. For Portuguese residents (those spending 183+ days/year in Portugal), only 50% of the gain is taxed, at progressive rates that top out at 48%. The IFICI regime (successor to NHR) does not exempt capital gains from Portuguese tax. The Canada-Portugal tax treaty covers capital gains, so the Portuguese CGT is creditable on your Canadian T2209. See our guide on Portugal's IFICI regime for residency planning implications.

Caribbean (Belize, DR, Panama, Costa Rica)

Belize remains a clean case: zero capital gains tax. You only owe Canadian CGT. The Dominican Republic charges 27% on net gain but exempts proceeds reinvested in Dominican real estate within one year. Panama applies 3% of gross at closing (treated as an advance on the 10% net-gain tax, with the balance settled on the annual return). Costa Rica introduced a 15% CGT in 2019. None of these four countries have a tax treaty with Canada, which means no reduced withholding rates — but the Foreign Tax Credit still applies. You just pay the full local rate, then offset on T2209 up to your Canadian tax on the same gain.

The Foreign Tax Credit: How T2209 Works

The Foreign Tax Credit (FTC) is the mechanism that prevents true double taxation. It is claimed on Form T2209 (Federal Foreign Tax Credits) and the corresponding provincial form (T2036 in most provinces). The credit directly reduces the Canadian tax you owe on income or gains that were also taxed by a foreign government.

How the credit is calculated: The FTC is the lesser of (a) the foreign tax actually paid on the gain, and (b) the Canadian federal tax attributable to the foreign-source gain. To calculate (b): take your total Canadian federal tax for the year, multiply by (the taxable amount of the foreign gain ÷ your total taxable income for the year). This fraction isolates what portion of your Canadian tax is specifically attributable to the foreign gain.

The cap in practice:If Mexico withheld ISR at 25% of gross and that comes to $40,000 USD ($55,000 CAD), but your Canadian federal tax attributable to the Mexican gain is only $38,000 CAD, your FTC is $38,000 — you permanently lose the $17,000 CAD excess. Conversely, if the Mexican ISR was only $25,000 CAD and your Canadian tax attributable to the gain is $38,000 CAD, the FTC is $25,000 and you still owe $13,000 in Canadian federal tax. The goal of the FTC is that you pay the higher of the two countries' rates — not the sum.

Nexus to a tax treaty: When Canada has a tax treaty with the country where the property is located (Mexico, Portugal, Spain, USA), the treaty specifies how taxing rights are allocated. Generally, the country of location (source country) taxes first; the country of residence (Canada) taxes second but provides the FTC. For countries without a treaty (Costa Rica, Dominican Republic, Belize, Panama), Canada still provides the FTC unilaterally under ITA sections 126(1) and 126(2) — there is no requirement for a treaty to claim the credit, only that the foreign tax is an income tax imposed on you by a foreign government.

Documentation required for T2209:You need the foreign tax assessment or withholding receipt, the amount in foreign currency, the type of tax (must be an income tax — transfer taxes do not qualify), the date paid, and the conversion to CAD. In Mexico, this is the notary's constancia de retención. In Portugal, it is the AT (tax authority) settlement document. In the Dominican Republic, a certificate from DGII. Keep these documents for at least six years — CRA can reassess T2209 claims within the normal three-year window, but foreign income can be reassessed indefinitely.

Note: the FTC and the T1135 reporting requirement are entirely separate obligations. You can owe T2209 without any T1135 obligation (personal-use property), and you can have a T1135 obligation with no FTC to claim (property that generated no income or gains in a given year).

The 2024 Inclusion Rate Change: The $250,000 Threshold

The 2024 federal budget introduced a significant change to Canada's capital gains inclusion rate, effective June 25, 2024. Under the new rules, the inclusion rate for individuals increases from 50% to 66.7% (two-thirds) on the portion of annual capital gains that exceed $250,000. The first $250,000 of capital gains per year remains at the 50% inclusion rate.

For corporations and most trusts, the 66.7% inclusion rate applies to all capital gains — there is no $250,000 individual exemption for non-individual taxpayers.

In practical terms for foreign property sellers: If you sell a foreign property in 2024 or later and realize a CAD net gain of $400,000, the tax calculation is:

• First $250,000 of gain: 50% inclusion = $125,000 added to income
• Remaining $150,000 of gain: 66.7% inclusion = $100,050 added to income
• Total taxable capital gain: $225,050
• At a 53% marginal rate, federal + provincial tax: approximately $119,277

Under the old 50% rule, the same $400,000 gain would have produced $200,000 of taxable income — a $25,050 difference in the taxable amount, and roughly $13,277 more in actual tax at the top marginal rate.

The $250,000 threshold is per individual per year, not per property. If you sell two foreign properties in the same year and realize a combined gain of $300,000, the 66.7% rate applies to $50,000 of the combined gain. Structuring the timing of sales across multiple calendar years — where feasible — can keep each year's gain under $250,000 and preserve the lower 50% rate.

For sales that closed before June 25, 2024, the old 50% rate applies to the full gain regardless of amount — the $250,000 threshold only affects transactions realized after that date. If you are holding a large-gain foreign property and considering selling, the June 25, 2024 cliff date is a real planning milestone.

Principal Residence Exemption for Foreign Property

The Principal Residence Exemption (PRE) is one of the most valuable tax shelters available to Canadians — it eliminates capital gains tax when you sell your home. But it does not apply to foreign property, for two reasons.

First, the PRE under ITA section 54 requires that the property be designated as your principal residence for each year you owned it. You can only designate one property per family unit per year. If your family already designates a Canadian home as your principal residence for the years you owned a foreign vacation condo, the foreign property cannot simultaneously be designated. Second, even if you do not own a Canadian home (making the foreign condo potentially your only property), CRA's administrative position has consistently been that a foreign property does not qualify — the property must be one you ordinarily inhabited while a Canadian resident, and a vacation home used a few weeks per year is unlikely to meet that standard under audit.

Planning implication:Never build a capital gains exit strategy for a foreign property that relies on the PRE. Budget the full capital gain, including foreign capital gains tax, as part of your eventual exit cost when you make the initial purchase decision. If the expected after-tax net return is acceptable including full CGT, the investment makes sense. If it only works with a PRE you're hoping will apply — reconsider the premise.

One scenario where foreign property and the PRE do intersect: if you sell your Canadian home while owning only a foreign property (no Canadian residence), you may claim the PRE on your Canadian sale. The foreign property sale remains fully taxable — there is no mechanism to transfer the PRE benefit to it.

For Canadians considering estate planning around foreign property, note that the PRE can be claimed in the year of death on the deceased's principal residence — but again, only if that property is a Canadian home, not a foreign vacation property.

Worked Example: Selling a Playa del Carmen Condo

Let's walk through a complete, realistic scenario to see all the moving parts in action. Sophie, a Canadian teacher from Vancouver, bought a two-bedroom condo in Playa del Carmen in 2015 for $250,000 USD. The CAD/USD exchange rate at purchase was 0.74 (meaning $1 USD = $1.351 CAD). She sells in 2025 for $350,000 USD. The rate at sale is 0.72 ($1 USD = $1.389 CAD). She is not a rental property owner — the condo was personal use throughout.

Step 1: Calculate the Adjusted Cost Base (ACB)

Sophie paid $250,000 USD in purchase price plus approximately 7% in Mexican closing costs ($17,500 USD for notary, ISAI transfer tax, and legal fees). Total acquisition cost in USD: $267,500.

At the 2015 purchase rate of 0.74: $267,500 USD ÷ 0.74 = $361,486 CAD

During ownership, Sophie also added a terrace cover and updated the kitchen — capital improvements totaling $12,000 USD in 2019 (rate was 0.75): $12,000 ÷ 0.75 = $16,000 CAD

Total ACB: $361,486 + $16,000 = $377,486 CAD

Step 2: Calculate Proceeds of Disposition

Sale price: $350,000 USD at the 2025 rate of 0.72: $350,000 ÷ 0.72 = $486,111 CAD

Selling costs: real estate commission (3%) and legal fees totaling $12,000 USD, at 0.72: $12,000 ÷ 0.72 = $16,667 CAD

Net proceeds: $486,111 − $16,667 = $469,444 CAD

Step 3: Calculate the Capital Gain

Capital gain = Net proceeds − ACB = $469,444 − $377,486 = $91,958 CAD

Since the gain is under $250,000, the 50% inclusion rate applies in full.

Taxable capital gain: $91,958 × 50% = $45,979 CADadded to Sophie's 2025 taxable income.

Step 4: Mexican ISR (Capital Gains Tax)

Mexico's notary withholds ISR on the sale. Sophie's advisor models both options:

• Option A — 25% of gross: $350,000 × 25% = $87,500 USD = $121,528 CAD
• Option B — ~30% of net gain (USD): USD gain = $350,000 − $267,500 − $12,000 − $12,000 = $58,500 USD. Mexican net-gain calculation ≈ $58,500 × 30% = $17,550 USD = $24,375 CAD

Option B produces dramatically lower Mexican tax. Sophie appoints a Mexican tax representative to elect Option B. ISR withheld: approximately $24,375 CAD.

Step 5: Canadian Tax and Foreign Tax Credit

Sophie is in BC at a 43.7% combined federal-provincial marginal rate. Canadian tax on the $45,979 taxable gain = approximately $20,093 CAD.

The T2209 Foreign Tax Credit is the lesser of: (a) Mexican ISR paid = $24,375 CAD, and (b) Canadian tax on the gain = $20,093 CAD. The FTC = $20,093 CAD. The excess Mexican ISR ($4,282 CAD) is forfeited.

Canadian tax after FTC = $20,093 − $20,093 = $0 additional Canadian tax owed.

Summary:Sophie's total tax bill on the sale is the Mexican ISR of ~$24,375 CAD (~$17,550 USD). She owes nothing additional to CRA. Had she not elected the net-gain option in Mexico and paid 25% of gross ($121,528 CAD), the cap would still have limited her FTC to ~$20,093 CAD — she would have paid $121,528 in Mexico and zero in Canada, losing over $100,000 CAD to Mexican tax that was unrecoverable. The net-gain election saves her over $97,000 CAD in this scenario.

This example illustrates the most important tax decision for Canadian sellers of Mexican property: always model the net-gain election before allowing the notary to default to 25% of gross. Appointing a Mexican tax representative costs a few hundred dollars; the savings can be in the tens of thousands.

Common Mistakes Canadian Sellers Make

After reviewing hundreds of foreign property transactions, these are the mistakes that repeatedly appear — and each one costs money:

1. Using the sale-date exchange rate for the ACB

The single most common error. The purchase price must be converted at the purchase-date rate. Using the current (sale-date) rate understates the ACB when CAD has weakened, creating a larger apparent gain and higher tax. CRA requires transaction-date rates; using the wrong date is a reporting error that survives audit.

2. Forgetting to include closing costs in the ACB

Transfer taxes, notary fees, legal fees, and buyer's agent commissions paid at purchase are all part of your ACB. In Mexico, closing costs of 6–9% on a $300,000 USD condo represent $18,000–$27,000 USD — at 2015 rates, roughly $24,000–$36,000 CAD of missed ACB. That's $12,000–$18,000 of unnecessary taxable gain at 50% inclusion.

3. Not tracking capital improvements

Every material capital improvement you made after purchase adds to your ACB and reduces your gain. Sellers routinely forget renovations from 5–10 years ago because they have no records. Start the ACB spreadsheet on day one and add every capital expenditure as it happens.

4. Defaulting to Mexico's 25% gross withholding without modeling the net-gain election

As shown in the worked example, the 25% gross withholding can dwarf your Canadian tax liability. The net-gain election requires advance planning (appointing a Mexican tax representative before closing) but can save tens of thousands. Ask your Mexican realtor about this before listing — the window to appoint a representative closes at the time of the notarial deed.

5. Expecting the PRE to apply

No Canadian has successfully claimed the Principal Residence Exemption on a foreign vacation property. Budget the full capital gain from day one.

6. Reporting the gain in the wrong year

The gain is reportable in the year the sale closes — not when a conditional offer was signed, not when a deposit was received. Report on Schedule 3 of the T1 return for the tax year in which title transferred.

7. Filing T2209 without documenting the foreign tax paid

The T2209 requires the foreign tax to be documented with official receipts. A notary's closing statement showing ISR withheld, an AT assessment from Portugal, or a DGII certificate from the DR — get these in writing at closing. Without documentation, CRA will deny the credit.

8. Using a general accountant instead of a cross-border specialist

Canadian foreign property tax is a specialty. A general CPA who does not regularly handle T2209 claims, foreign ACB calculations, and ISR election analysis will likely miss the optimizations that matter most. The additional cost of a specialist — typically $500–$1,500 for a foreign property disposition — is recaptured many times over in correctly claimed ACB additions and optimized FTC calculations.
