This is the most-confused comparison in Canadian personal finance. TFSA and HISA aren't exclusive — a TFSA is an account *type* (a tax wrapper), while a HISA is a *product* (a savings account paying interest). The optimal setup: a TFSA-HISA at EQ Bank, Wealthsimple, or similar — 4% interest tax-free until you hit your TFSA limit, then a regular HISA for the overflow.
An account type the government created in 2009. Tax-sheltered — no tax on interest, dividends, or capital gains. Can hold cash, stocks, ETFs, bonds, mutual funds, GICs, or a HISA.
A savings account paying higher interest than chequing. Sold by banks and fintechs. Can sit in a regular taxable account or inside a TFSA wrapper.
| TFSA | Regular HISA | |
|---|---|---|
| Tax on interest/growth | None — ever | Fully taxable at marginal rate |
| Annual contribution limit | $7,000 (2025) · $7,500 (2026) | Unlimited |
| Lifetime contribution limit | Cumulative since age 18 (2009+) | Unlimited |
| Liquidity | Withdraw anytime | Withdraw anytime |
| CDIC coverage | Yes — $100K separate from regular accounts | Yes — $100K combined |
| Eligible investments | HISA · GIC · stocks · ETFs · bonds | HISA-only |
| Re-contribute withdrawals | Next calendar year | Same day |
| Account fee | Usually $0 at HISA providers | $0 |
In a regular HISA at marginal rate 35%, that's $700/yr to the CRA. Across 10 years (compounding): roughly $7,400 in lost tax.
In a TFSA-HISA: zero tax forever. The same $50K grows to $74K instead of $66K over a decade.
Always max your TFSA contribution room before using a regular HISA for emergency funds.
