Overdraft protection in Canada typically costs a monthly fee plus interest on the overdrawn amount — at TD and CIBC, that interest rate was confirmed at approximately 21% per year directly from each bank’s website in September 2026, plus a separate monthly plan fee. It prevents NSF fees, which as of March 12, 2026 are capped at $10 per occurrence under federal regulation (down from the pre-2026 $45–$48). Digital banks (EQ Bank, Simplii, Tangerine) do not offer overdraft — instead, they decline transactions at $0.
Quick answer: Overdraft protection: monthly fee + roughly 21% interest on amount used (confirmed at TD and CIBC; confirm your own bank’s current rate). Prevents NSF fees, now capped at $10 federally. Not available at EQ Bank, Simplii, or Tangerine.

How Overdraft Protection Works
When you spend more than your account balance, two things can happen without protection:
- Transaction declined (debit purchases, bill payments)
- NSF fee charged — capped at $10 as of March 12, 2026 — when a pre-authorized debit or cheque is returned
With overdraft protection, your bank covers the shortfall up to your approved limit, then charges:
- A monthly flat fee whether you use it or not (amount varies by bank — confirm current fee)
- Interest (around 21% per year at TD and CIBC) on the amount overdrawn, for the number of days you’re in the negative
How Overdraft Interest Is Calculated
Example (illustrative, using a 21% rate): You overdraw your account by $400 for 10 days.
$$ ext{Interest} = $400 imes rac{21%}{365} imes 10 pprox $2.30$$
Add the monthly protection fee (confirm current amount with your bank) and the total cost of covering a $400 shortfall for 10 days is modest compared to a missed payment — but confirm both figures with your bank before relying on this estimate.
Overdraft Protection vs. NSF Fees — Which Is Cheaper?
| Scenario | Cost |
|---|---|
| 1 NSF fee (per returned item, 2026 federal cap) | $10 |
| 3 NSF fees across separate 2-business-day windows | $30 |
| Overdraft (1 month, $400 for 10 days, illustrative at 21%) | ~$2.30 interest + monthly fee (confirm amount) |
| Overdraft (annual cost, fee-only, no use) | Confirm your bank’s monthly fee × 12 |
Verdict: Now that NSF fees are capped at $10, the case for paying a recurring monthly overdraft fee “just in case” is weaker than it was before March 2026 — do the math with your own bank’s specific monthly fee before deciding whether overdraft protection or simply risking an occasional $10 NSF fee is cheaper for your situation.
How to Set Up Overdraft Protection
- Call your bank or visit a branch — approval required (soft credit check in most cases)
- Choose your overdraft limit (typically $100–$5,000 depending on account and credit history)
- Confirm the current monthly fee and interest rate directly with your bank
- Sign the overdraft agreement — protection is typically active within 1 business day
Most Big 5 banks also allow you to request overdraft protection through online banking or the mobile app.
Cheaper Alternatives to Overdraft Protection
| Alternative | Interest Rate | Fee | Best For |
|---|---|---|---|
| Overdraft protection | ~21% (TD, CIBC; confirm your bank) | Monthly fee — confirm amount | Occasional, small shortfalls |
| Personal line of credit (PLOC) | 7%–12% | Usually $0/year | Larger, predictable shortfalls |
| Low-interest credit card | 12%–20% | Annual fee varies | Short-term, pay off quickly |
| Cash buffer (self-insured) | 0% | $0 | Disciplined savers |
| EQ Bank (declines at $0) | N/A | $0 | Users with tight budgets |
Personal line of credit: If your bank approves a PLOC at prime + 2%–4%, it is typically cheaper than overdraft for borrowing more than a few hundred dollars. The annual fee is usually $0. You draw from it only when needed and repay at a lower interest rate.
Cash buffer habit: Keeping $500–$1,000 as a permanent minimum in your chequing account is effectively free overdraft protection. It requires discipline but eliminates both the monthly fee and the interest cost.
What to Do If You Have No Overdraft and an NSF Hits
- Deposit funds immediately — even a few hours before end of business day may allow the transaction to clear on re-presentation
- Call your bank — explain the situation and request a one-time NSF fee waiver (commonly granted for first occurrences)
- Contact the payee — if the payment was a bill or rent, notify the payee immediately; most will allow a short grace period
- Set up overdraft protection — then ensure it doesn’t happen again
