What Is a HISA (High-Interest Savings Account)?

A HISA is a savings account offering higher interest rates than traditional bank savings accounts. In 2026, HISAs typically offer 4.5–5.5% annual interest, compared to 0.05–0.5% at big banks. The tradeoff: HISAs often have limited withdrawal options or require online access. HISAs are ideal for emergency funds, down payment savings, or any money you need accessible but want to earn interest. They're safer than GICs because funds remain liquid (accessible anytime).

CDIC Insurance Coverage: $100k Per Category

Deposits at CDIC-insured institutions are protected up to $100,000 per depositor, per institution, per category. Categories include: deposits in your name only, deposits in your name jointly with another person, deposits in your name as a trustee, and deposits in registered accounts (TFSA, RRSP, FHSA). This means you can have $100,000 in a personal HISA and $100,000 in a TFSA HISA at the same bank, both fully covered. Ensure your HISA provider is CDIC-insured (most online banks are).

Promotional Rates vs. Regular Rates

Many HISAs offer "promotional" rates (e.g., 5.5% for 3 months) that drop to a lower "regular" rate (e.g., 4.5%) after the promo period. Promotional rates are useful for short-term saving (e.g., down payment in 6 months), but expect the rate to drop. Some HISAs maintain consistent rates without promos. Compare apples-to-apples: the regular ongoing rate, not the promo rate. $10,000 earning 5.5% for 3 months then 3.5% for 9 months averages ~4.3% annually.

HISA in TFSA vs. Non-Registered Account

A HISA in a TFSA is ideal: interest earns tax-free forever, and you have CDIC coverage up to $100,000. A HISA in a non-registered account means interest is fully taxable annually. Interest income has no deduction—you pay tax on 100% of the interest at your marginal rate. At 45% tax, $5,000 in interest costs $2,250 in tax. Using a TFSA HISA first (if you have room) is a no-brainer: same interest, zero tax.

HISA vs. GIC Comparison

HISAs offer instant access and flexible withdrawal; GICs lock up your money for a fixed term (3 months to 5 years) but typically offer slightly higher rates (4.8–5.8% in 2026). GICs are better for money you won't need (e.g., education savings, long-term goals). HISAs are better for emergency funds or short-term savings. A balanced strategy: emergency fund in HISA, longer-term savings in GIC ladder.
