The seamless global market is a myth. For a Canadian resident, buying US equities isn't just a click of a button; it is a complex navigation through tax treaties, currency spreads, and IRS reporting requirements that most retail platforms conveniently ignore.
Brokers claim zero commissions while hiding a 1.5% to 2% spread on currency conversion. If you are buying $10,000 USD of Apple stock, you've already lost $200 before the trade even executes. This is why understanding Norbert's Gambit is critical for any serious portfolio.
View AuditMarketing often suggests the TFSA is "tax-free" for everything. It isn't. The IRS does not recognize the TFSA as a pension account, meaning a 15% non-resident withholding tax is dragged from every US dividend. You are losing yield silently every single quarter.
Compare AccountsBuying a Canadian-listed ETF that holds US stocks (like VUN.to) often introduces a second layer of tax drag. You might be paying internal fees and taxes that a direct US-listed ETF (like VTI) would avoid in the right account type.
Analyze ETFsInvesting across the 49th parallel requires an engineering mindset toward taxation. The Canada-US Tax Treaty is designed to prevent double taxation, but it does not automate efficiency. Most investors fail to realize that the "withholding tax" is a definitive cost unless held in an RRSP. In an RRSP, the IRS recognizes the tax-exempt status, allowing 100% of dividends to cross the border.
However, the moment you move to a taxable (Non-Registered) account, the game changes. You must track your adjusted cost base (ACB) in Canadian dollars using the exchange rate on the date of every single transaction. Failure to do so results in CRA penalties or overpayment of capital gains tax. If your foreign property exceeds $100,000 CAD, the T1135 Form becomes a mandatory annual filing.
Beyond income tax, there is the looming shadow of the US Estate Tax. Even if you never live in the States, owning significant US "situs" assets can trigger IRS claims upon your death if your global estate exceeds certain thresholds. This is not just a problem for the ultra-wealthy; it is a structural risk for any long-term compounder.
Yes, always. Without it, the IRS takes 30% of your dividends. With it, the treaty reduces this to 15%. Most Canadian brokers collect this digitally, but you must verify its status every three years. See our guide on Withholding Tax Compliance.
For US dividends, yes. It is the only account where the 15% tax is waived entirely. In a TFSA or RESP, that money is gone forever—you cannot claim a Foreign Tax Credit for taxes paid in a tax-sheltered account.
The US generally does not tax capital gains for non-resident Canadians on publicly traded stocks. You pay the tax to the CRA. The friction here is the currency conversion and the reporting of the gain in CAD, which often confuses DIY investors.
