Who Gets to Tax You After You Leave Canada?

Imagine moving abroad, thinking you’re done with Canadian taxes, and suddenly both Canada and your new country want to tax you.

Now you’re stuck in a messy tax love triangle you never signed up for, with two governments fighting over the same dollar.

That’s where tax treaties come in and after we explain it to our clients who are moving abroad they feel a lot more relieved. 

In this blog post, I’ll break down how they work and 7 ways they can reduce your taxes when you leave Canada. But first…

Why Are Tax Treaties So Important?

Moving to a new country triggers a kind of “tax tug-of-war” between Canada and your new home. 

A Tax Treaty acts as a legal referee, deciding which country taxes your income first so you don’t pay twice. It also establishes withholding rates for dividends and interest and defines residency “tie-breakers,” which I’ll get into later in this video.

First Step: Check the Treaty Map

Canada has active tax treaties with over 90 countries (about half the world!). Treaties aren’t one-size-fits-all. Every agreement has unique “quirks” depending on the country. For example, the Canada-US treaty is famous for its 0% interest rate and “Step-Up” rules, while others might have different rules for pensions or rental income. 

Before you pack your bags, it’s vital to research the specific treaty for your new home and the impact it will have on your specific assets. Also, be aware of any important updates which can change at any moment. For example, Canada suspended our tax agreement with Russia back in 2024. 

Moving to a Non-Treaty Country?

Without an agreement, you face the “Wild West” of taxation, and the main issue is risk of double tax & no safety net: Without treaty coordination, you risk paying both countries for the same income and lose the “safe harbours” that protect your foreign business and investments from aggressive CRA claims.

The Bottom Line: If your new home lacks a treaty, you must be extra careful with your paperwork. Consult with cross-border professionals like ourselves to ensure you aren’t paying more than your fair share. 

Here are the ways tax treaties can protect you and potentially reduce your taxes.

1. The “Tie-Breaker” Residency Shield

Under Canadian domestic law, if you leave but keep a house or bank account in Canada, the CRA may still call you a “Factual Resident“ taxing your worldwide income.

However, the treaty’s residency tie-breaker rules can override this. Even with Canadian ties, a treaty can “deem” you a non-resident if your life is truly centred elsewhere. Once this happens, you become a Deemed Non-Resident; Canada generally loses the right to tax your foreign salary.

The Example: Tristan’s Move

Tristan moves from Toronto to Dubai (0% tax). He rents an apartment and works there but keeps his Toronto condo “just in case.” Under the Canada–UAE Tax Treaty (Article 4), the treaty applies a hierarchy:

1. Permanent Home
2. Centre of Vital Interests (Work, social life)
3. Habitual Abode

Since Tristan’s daily life and job are in Dubai, the treaty “breaks the tie” in favour of the UAE. This forces the CRA to stop taxing his global income, legally dropping his tax rate on those Dubai earnings from 54% to 0%.

Note that becoming a non-resident is a huge topic in itself and it can get very messy, and I’ve made another video about that so check it out. Now if you’re a retiree, the next one is for you.

This is exactly where a lot of people engage in our services here at Blueprint, because non-residency issues can get very complicated. 

2. For Retirees: Reduction of Withholding Tax on CPP and OAS

If you retire in a country without a tax treaty, the CRA automatically keeps a 25% non-resident tax from every CPP and OAS payment. For a typical retiree, this “tax haircut” can cost thousands of dollars every year.

However, treaties with countries like the U.S. and the U.K. provide a 100% shield. These agreements state that social security benefits are taxable only in your new country of residence. Since Canada waives its right to tax them, your withholding drops from 25% to 0%.

Example: Joshua’s Retirement

Joshua moves to Florida for his retirement. His combined CPP and OAS payments total $1,800 per month.

• Without the Treaty: The CRA would withhold $450 every month, leaving him with only $1,350. (25%)
• With the Treaty: Because he is a U.S. resident, Canada withholds $0. Joshua receives the full $1,800. Under U.S. rules, only up to 85% of that $1,800 is even considered taxable income, often resulting in a much lower total tax bill than he would have paid in Canada. In some cases, a categorically modest income can even be taxed as low as 50%.

3. Reduced Withholding on RRSP/RRIF Withdrawals

For many Canadians, the RRSP or RRIF is their largest nest egg. Normally, if you live abroad, the CRA hits every withdrawal with a flat 25% non-resident withholding tax. This can be a major blow to your retirement budget, especially if you are living in a country with a higher cost of living.

If you’re watching this, you’re already ahead of the game because now you know tax treaties often provide a pension discount—but here’s the critical part: this lower rate often only applies to periodic payments, not lump-sum withdrawals.

The Key Difference:

• Lump-Sum RRSP Withdrawal: 25% withholding tax—no treaty reduction available
• Periodic RRIF Payments: 15% withholding tax under most treaties (U.S., Australia)

Example: Tristan’s Monthly Income

Tristan has retired to Australia. He sets up a RRIF to pay him $3,000 per month to cover his living expenses.

• Without the Treaty: The CRA takes $750 in tax every month, leaving him with $2,250.
• With the Treaty: Under the Canada–Australia Tax Treaty (Article 18), the rate on periodic pension payments is capped at 15%. The CRA now only takes $450, putting an extra $300 per month ($3,600 per year) directly into Tristan’s pocket.

Knowing the rules is simple; navigating the compliance is not. While preparing for a move, you have a million things to worry about. Making a mistake on filling out a tax form which could affect you with thousands of dollars lost is not one of them.

If you invest in stocks or bonds, pay attention. 

4. Exemption of Capital Gains on “Movable” Property

Impact: Prevents Canada from taxing gains on stocks/bonds after you leave.

Under Canadian domestic law, once you leave, Canada generally only retains the right to tax “Taxable Canadian Property” (like real estate).

A tax treaty provides a “Safe Harbour“ for movable property (public stocks, bonds, mutual funds). It legally bars Canada from taxing any growth that happens after your departure date.

The “Step-Up” Hand-Off

The treaty ensures your new country doesn’t tax you on the growth that happened while you were still in Canada:

1. Departure: You pay a one-time “Departure Tax” to Canada on the growth of your assets up to the day you leave.  Keep in mind that your departure date is critical in determining the deemed value of your property and your reporting deadlines.
2. The Step-Up: The treaty (e.g., Canada–UK Article 13) allows your new country to treat the value on the day you arrived as your “new” cost. This is called a Step-Up in Basis.

Example: Tristan’s Move to the United Kingdom

• While in Canada: Tristan buys stocks for $100,000.
• The day he Leaves: The stocks are worth $500,000. Tristan pays Canada “Departure Tax” on the $400,000 gain.
• 5 Years Later: Living in London, the stocks are now worth $800,000. Tristan sells them.

The Result: Because of the treaty, the UK recognizes Tristan’s “new” starting price of $500,000. He only pays UK tax on the $300,000 in profit made while living there. Canada is legally barred from touching any of that post-departure growth.

5. Dividend Withholding Reduction

If you hold shares in Canadian blue-chip companies (like banks or utilities) as a non-resident, the CRA’s default rule is to take a 25% flat cut of every dividend payment before you even see it.

Tax treaties almost universally lower this barrier. For regular investors, treaties like the Canada–U.S. and Canada–U.K. agreements drop the rate to 15%.

Example: Joshua’s Passive Income

Joshua moves to the U.S. and keeps his Canadian brokerage account, which pays him $10,000/year in dividends from Canadian banks.

• Without the Treaty: The CRA treats him as a “statutory” non-resident and withholds $2,500 (25%).
• With the Treaty: Under Article X of the Canada–U.S. Treaty, the rate is slashed to 15%. The CRA only takes $1,500, putting an extra $1,000 back into Joshua’s pocket every single year.

6. Business Profits Exemption

Impact: Prevents Canada from taxing your new foreign business.

Under domestic law, the CRA can claim you are “carrying on business in Canada” simply by soliciting orders or offering services to Canadians. However, treaties introduce the “Permanent Establishment” (PE) rule, which legally bars Canada from taxing business profits unless you maintain a fixed physical office or branch within the country.

7. Interest Income Exemption

While Canadian domestic law generally exempts “arm’s length” interest (interest from unrelated parties like banks), the 25% tax still applies to non-arm’s length or “participating” debt. A tax treaty provides an essential safety net by capping or eliminating this tax entirely for residents of treaty countries. For example, under the Canada–U.S. Treaty, most interest—even from related parties—is slashed to 0%, effectively removing the tax burden on your Canadian savings and private lending on the Canada side.

Note that these are ways that tax treaties can decrease your taxes, but there are a lot of pitfalls that can occur that will increase your taxes. Tax treaties can be your allies, but they aren’t “set it and forget it.” A single mistake in how you exit or how you report your assets can trigger a trap that takes years to untangle.
