Open KOHO Free — Code 45ET55JSYASince all growth inside a TFSA is tax-free, the most valuable investments to hold are those with the highest expected returns and the highest tax drag if held in a non-registered account. The goal is to maximize what the tax shelter actually shelters.
| Investment Type | Tax-Free Benefit | Fit for TFSA |
|---|---|---|
| Canadian growth stocks | Capital gains + eligible dividends | Excellent |
| Broad market ETFs (Canadian) | Capital gains + dividends | Excellent |
| High-interest savings (HISA) | Interest income (otherwise fully taxed) | Good |
| GICs | Interest income sheltered | Good |
| Canadian dividend stocks | Eligible dividends sheltered | Good |
| US stocks / US ETFs | Capital gains sheltered, but 15% withholding tax on dividends NOT recoverable | Moderate — better in RRSP |
| Bonds / bond ETFs | Interest income sheltered | Good (better in TFSA than non-reg) |
| REITs | Distributions sheltered | Good |
For most Canadians, a low-cost all-in-one ETF (like XEQT, VEQT, XGRO, or VGRO from iShares and Vanguard Canada) is the best thing to hold in a TFSA. These provide instant diversification across thousands of stocks globally, with MERs under 0.25%. Over 20–30 years, the compounding of tax-free returns on a diversified equity portfolio is extraordinarily powerful.
If you are comfortable with individual stock picking, high-conviction Canadian growth stocks are excellent TFSA candidates. Capital gains on Canadian stocks held in a TFSA are completely tax-free — compared to a 50% inclusion rate in a non-registered account. A stock that doubles inside your TFSA means 100% of the gain stays with you.
Canadian eligible dividends receive favourable tax treatment outside a TFSA through the dividend tax credit — but they are still taxed. Inside a TFSA, those dividends are completely tax-free. Top Canadian dividend payers like banks, pipelines, and REITs are popular TFSA holdings.
Interest income is the most heavily taxed investment income in Canada — it's taxed at your full marginal rate. Holding a HISA inside your TFSA eliminates this tax entirely. Several Canadian fintechs and credit unions offer competitive HISA rates inside a TFSA. This is a good short-term holding while you decide on longer-term investments.
Guaranteed Investment Certificates inside a TFSA shelter what would otherwise be fully taxable interest income. Shop around for the best GIC rates — credit unions and online banks often beat the Big 5. Non-redeemable GICs typically offer higher rates but lock your money in for the term.
