To begin with, your tax obligations depend on whether the CRA sees you as a resident or not. It’s not just about where your passport is stamped or how many days you’ve spent in the country. Canada uses a mix of facts to decide this, looking at your “residential ties.”
If you maintain strong connections like a home in Canada, a spouse or dependents still living there, or even things like a Canadian driver’s license and bank accounts, you could be considered a “factual resident.” That means you’d report your worldwide income on a Canadian return, just like if you never left. Reports show that around 4 million Canadians live abroad, and many fall into this category without realizing it, leading to unexpected filing requirements.
On the flip side, if you’ve truly cut those ties, like sold your house, moved your family, and established a permanent life elsewhere, you might qualify as a non-resident.
Moreover, if you are spending 183 days or more in Canada in a year, it can “deem” you a resident anyway, pulling you back into the tax net.
However, tax treaties typically override this rule, if you are a resident of a treaty country, the tie-breaker provisions usually prevent Canada from taxing you as a resident even if you hit 183 days.
In these cases, you are treated as a deemed non-resident of Canada, so only Canadian-source income is taxable here (not your worldwide income). And if you’re tied to a country that has a tax treaty with Canada, that agreement might step in to clarify things, often reducing double taxation but not erasing your duties entirely.
Residency isn’t a light switch you flip off when you board the plane. It’s more like untangling a web, and getting it wrong can mean penalties or missed refunds.
In most cases, part XIII rules require that the payers withhold 25% tax at source.
However, it is also common to file a return and report net income after expenses, claim treaty-reduced rates, and receive a refund. In the case of rental income, you can pay based on net profit, rather than gross rent, under Section 216.
In the case of pensions, Section 217 could put you on graduated rates, which could cost less if your income is small. You may not file a return when you are not claiming anything back, and your only Canadian income is fully withheld. Voluntary filing may, however, open benefits or credits in certain circumstances. Tax treaties count a lot in the world. Canada has a treaty with such countries as France, Spain, Italy, Australia, Japan, South Korea, Mexico, among others and frequently limits withholding to lower rates (e.g. 15% on dividends or 10% on royalties).
In the absence of a treaty, there is a default 25%.
Scenario | Location Example | Likely Status | Filing Trigger | Potential Benefit |
Strong ties remain | Family still in Canada, home kept | Factual resident | Worldwide income | Full T1 return required |
Minimal ties, under 183 days | New permanent home in Portugal or Thailand | Non-resident | Canadian-source income only | File if refund/credits due (e.g., Section 216 for rentals) |
183+ days in Canada | Short-term return visits add up | Deemed resident | Worldwide income | File as resident |
Treaty country resident | Living in Australia, Mexico, Germany | Often deemed non-resident if treaty tie-breaker applies | Canadian-source only, reduced rates | Lower withholding via treaty |
Take the example of a retired teacher who is in Mexico and is collecting CPP and OAS. Withholding is applicable, but it might have a lower overall effective tax, notwithstanding, by filing under Section 217.
Or a Spanish freelance working on rental income at a condo in Vancouver. Electing Section 216 incurs maintenance costs (maintenance, property taxes), which may decrease the tax less than the flat amount of 25, which is being withheld.
A Canadian dividend-earning engineer in Singapore? The Canada-Singapore treaty can reduce withholding to 15% and claim it in absentia to one’s advantage.
Selling a cottage in New Zealand? Include the capital gain; there are new rules, but treaties assist in coordinating with your new tax system.
CRA has become more compliance-oriented, and data is being shared internationally; hence, accurate reporting does not come as a surprise.
Begin by applying to determine residency through Form NR73 or NR74, which is easy and provides official clarity. File easily in foreign countries with the help of NETFILE or certified software. Document connections have cut (e.g. documents of sale, change of addresses) to be audited. By the beginning of 2026, none of the sweeping changes affected expat rules, but some minor bracket modifications and credit changes remain.
Preemptive action usually results in savings or refunds as opposed to penalties. Emigrating to Canada is a great adventure, but just one glance at your tax status keeps the gears turning.
You are going to Lisbon or Dubai, or Auckland or wherever, ask yourself the same questions: What ties are left? Any Canadian income? The responses determine whether or not you file, and frequently, how to reduce what you owe. In need of assistance in unwinding the situation.
