You can work remotely in Canada as a U.S. citizen for up to six months on visitor status, provided your employer stays in the United States, your paycheck comes from that U.S. employer, and your work doesn’t compete with Canadian workers. Cross any of those lines and you need a work permit. Stay longer than 183 days in a calendar year and you owe Canadian tax on your worldwide income for the whole year, even though the U.S. never stops taxing you either. The immigration side is usually the easy part.
What Counts as “Work” Under Canadian Immigration Rules
Canadian regulations define “work” as an activity that earns wages or commission, or that directly competes with Canadian citizens or permanent residents in the labor market.1Department of Justice Canada. Immigration and Refugee Protection Regulations (SOR/2002-227) – Section 2 That definition is the whole reason the visitor pathway exists. If you’re in a Vancouver apartment writing code for a company in Austin, paid in U.S. dollars, with no Canadian clients and no Canadian coworker whose job you’re taking, Immigration, Refugees and Citizenship Canada takes the position you’re not “working” under the immigration statute at all.
Canada has no formal digital nomad visa, but the practical effect of that interpretation is the same: you enter as a visitor and open your laptop. At the border you’ll need to satisfy the officer that your stay is temporary, your employer is foreign, and you’ll leave when your authorized period ends.
The Six-Month Visitor Limit
Most visitors to Canada are authorized to stay up to six months.2Canada.ca. Visitor Visa: About the Document U.S. citizens don’t need a visitor visa to enter, but the border officer records your entry date and expects you gone by the six-month mark unless you’ve extended.
To stay longer, apply for a visitor record before your original six months expire. A visitor record isn’t a visa or a work permit; it extends your authorized stay as a visitor. The application fee starts at $100 CAD, and recent processing times have stretched to roughly 10 months, so early filing matters.3Canada.ca. Extend Your Stay in Canada (Visitor Record) While the extension is pending you can remain in Canada under implied status, even after your original six months lapse, but you cannot leave the country and re-enter on implied status alone.
When You Actually Need a Work Permit
The visitor route only works when your employer and the paying relationship stay outside Canada. You’ll need a work permit if:
- A Canadian company, or a Canadian branch of your U.S. employer, is paying you or directing your work.
- Your role involves selling to Canadian customers or providing services that compete with local workers.
- You want to stay past the six-month visitor window and don’t just want to remain a visitor.
For U.S. citizens the most common pathway is CUSMA, the Canada-United States-Mexico Agreement that replaced NAFTA. CUSMA lets professionals in specified occupations get a work permit without their employer going through a Labour Market Impact Assessment, as long as you have a pre-arranged job with a Canadian employer in a qualifying field and hold the required credentials.4Government of Canada. Canada-United States-Mexico Agreement (CUSMA) – Chapter 16 – Temporary Entry for Business Persons The list spans dozens of professions, from engineers and accountants to scientists and medical professionals.5Government of Canada. Business People: Work in Canada Under a Free Trade Agreement U.S. citizens can often apply at a Canadian port of entry rather than through the online system, which makes CUSMA faster than most other work permit routes. Separate LMIA-exempt categories exist for intra-company transfers, treaty traders and investors, and specialized-knowledge workers.
The 183-Day Tax Trap
The immigration and tax systems don’t talk to each other. Nothing about extending your visitor stay stops you from becoming a Canadian tax resident, and this is where remote work from Canada gets expensive.
Spend 183 days or more in Canada in a calendar year without establishing significant residential ties, and the Canada Revenue Agency treats you as a “deemed resident” for the entire year.6Canada Revenue Agency (CRA). Deemed Residents of Canada Deemed residents owe Canadian income tax on worldwide income for the full year, not just the portion earned while physically in Canada.7Canada Revenue Agency (CRA). Income Tax Folio S5-F1-C1, Determining an Individuals Residence Status Your U.S. salary counts, even though it’s paid by an American employer in U.S. dollars.
If you establish significant residential ties earlier (renting an apartment, opening Canadian bank accounts, bringing your family), the CRA may treat you as a “factual resident” before hitting 183 days. Factual residents who arrive mid-year are taxed only from the date residency begins, while deemed residents pay for the whole year. Canadian tax rates are generally higher than U.S. federal rates, and once provincial tax layers on, the total bill can be significant.
Your US Tax Filing Doesn’t Stop
The United States taxes its citizens on worldwide income regardless of where they live. Moving to Canada doesn’t change that. You file a U.S. federal return reporting all income, including anything Canada is also taxing. Relief comes from credits and exclusions, not exemption.
The Canada-U.S. Tax Treaty sets up a layered credit system to prevent double taxation: Canada allows a deduction from Canadian tax for income tax paid to the U.S., and the U.S. allows a credit against U.S. tax for income tax paid to Canada.8Canada.ca. Convention Between Canada and the United States of America With Respect to Taxes on Income and on Capital Because Canadian rates are typically higher, most people end up paying roughly the Canadian rate overall, with the foreign tax credit wiping out most or all of the U.S. liability on the same income.
The Foreign Earned Income Exclusion is a separate option, but qualifying requires either 330 full days outside the U.S. in a 12-month period (physical presence test) or bona fide residence in a foreign country for a period that includes a complete tax year.9Internal Revenue Service. Foreign Earned Income Exclusion – Physical Presence Test A few months in Canada won’t get you there. For most people on a standard salary, the foreign tax credit is the better tool anyway.
Canadian Bank Accounts Trigger US Reporting
Opening a Canadian account is often a practical necessity, and Canadian banks will open accounts for non-citizens; you typically need to appear in person with two pieces of original ID such as your U.S. passport and a document showing your name and address.10Canada.ca. Opening a Bank Account But those accounts pull you into two separate U.S. reporting regimes with harsh penalties.
The first is the FBAR. If the combined balance of all your foreign financial accounts, including accounts where you only have signature authority, exceeds $10,000 at any point in the year, you file FinCEN Report 114 by April 15, with an automatic extension to October 15.11Financial Crimes Enforcement Network (FinCEN). Report Foreign Bank and Financial Accounts The threshold is aggregate: two accounts holding $6,000 each trigger it. Non-willful failure to file carries a penalty of up to $10,000 per violation. Willful violations jump to the greater of $100,000 or 50% of the account balance.
The second is FATCA. If your foreign financial assets exceed higher thresholds, you also file IRS Form 8938 with your tax return. For U.S. citizens living abroad, the thresholds are $200,000 on the last day of the year or $300,000 at any point during the year for single filers, and $400,000 or $600,000 for joint filers.12Internal Revenue Service. Summary of FATCA Reporting for US Taxpayers The two regimes overlap but are filed with different agencies, and you may need to file both.
Social Security Stays With One Country
Without a treaty you could end up paying into both U.S. Social Security and the Canada Pension Plan on the same earnings. The U.S.-Canada Totalization Agreement assigns coverage to one country only. The general rule is that you pay into the system of the country where you physically work.13Social Security Administration. U.S.-Canadian Social Security Agreement If a U.S. employer sends you to Canada temporarily, the “detached worker” rule lets you stay in the U.S. system for up to 60 months and skip CPP contributions. To prove the exemption, your employer requests a Certificate of Coverage from the Social Security Administration, which you present to the CRA.14Social Security Administration. Certificate of Coverage Self-employed people follow a different rule: you pay into the system of the country where you reside, meaning CPP if you’re self-employed and living in Canada.
Healthcare Isn’t Automatic
Canadian provincial health insurance is publicly funded but not available to visitors. You have to establish residency in a province, and most provinces impose a waiting period of roughly three months after you arrive.15Province of British Columbia. Coverage Wait Period Under six months as a visitor, you won’t qualify at all. Your U.S. health insurance may or may not cover you across the border, and many domestic plans offer limited or no international coverage. Check your policy before you leave, and if it doesn’t travel with you, buy a private international or travel health policy. A single emergency room visit without coverage can run into the thousands.
Warn Your Employer About Permanent Establishment
Employers sometimes veto Canada arrangements because of their own tax exposure, and understanding why helps you have a productive conversation before you buy a plane ticket.
The main concern is “permanent establishment.” If a company is deemed to have a PE in Canada, it becomes subject to Canadian corporate income tax on profits attributable to that establishment. Updated OECD commentary released in November 2025 provides a useful safe harbor: if an employee works from a home or other location in another country for less than 50% of their total working time over any 12-month period, that location generally won’t create a PE. Even above 50%, a PE arises only if there’s a commercial reason for the presence, such as regularly serving Canadian customers. Working from Canada for personal or lifestyle reasons doesn’t count as commercial. The OECD commentary isn’t binding, but Canada’s tax treaties follow the OECD model and the CRA looks to it when interpreting PE questions.
If your presence does create an employment relationship under Canadian law, your U.S. employer may need to register for a Canadian Business Number, open a payroll program account, and begin withholding Canadian federal and provincial income tax. Some provinces also impose employer health taxes above certain payroll thresholds. These are the employer’s obligations, not yours, but they explain why some companies simply say no.
Don’t Forget the State You Left
Federal taxes attract most of the attention, but the state you left may still expect a return. California, New York, New Mexico, South Carolina, and Virginia have aggressive residency rules that can keep you on the hook for state income tax after you’ve gone abroad, particularly if you keep a driver’s license, voter registration, or property in the state. If your last state of residence was Alaska, Florida, Nevada, South Dakota, Texas, Washington, or Wyoming, none of which have a state income tax, this isn’t an issue. For everyone else, sever ties cleanly before you leave: update your driver’s license, close local accounts, change your voter registration. A missed state return can accumulate penalties and interest while you’re paying attention to everything else.
A Note for Freelancers on GST/HST
If you’re self-employed, Canada’s GST and HST apply to taxable supplies made in Canada. Once your revenue from taxable supplies exceeds $30,000 CAD in any four consecutive calendar quarters or in a single quarter, you must register and start charging GST/HST.16Canada.ca. When to Register for and Start Charging the GST/HST Services provided to clients outside Canada are generally zero-rated, so you wouldn’t actually collect tax on U.S. invoices, but the $30,000 threshold is measured on worldwide taxable supplies, and if you cross it you still register and file returns. Registration also lets you claim input tax credits on Canadian business expenses.
