Overview
The MBNA True Line Gold Mastercard is the lowest-rate credit card in the MBNA lineup — and one of the lowest-rate cards available in Canada. With a 10.99% interest rate on purchases, it undercuts most low-rate competitors that sit at 12.90–12.99%. The trade-off is a $39 annual fee, but if you carry a balance, the interest savings easily outweigh that cost.
Unlike the no-fee MBNA True Line Mastercard (12.99%), the Gold version drops the rate by a full 2 percentage points and adds Purchase Protection and Extended Warranty insurance — uncommon perks for a low-interest card. It also carries a lower 13.99% balance transfer rate, making it a solid option for consolidating higher-interest debt.
As a Mastercard, it works at Costco, which only accepts Mastercard for credit payments in Canada.
Interest Rate Breakdown
| Type | Rate |
|---|---|
| Purchases | 10.99% |
| Balance Transfers | 13.99% |
| Cash Advances | 24.99% |
The 10.99% purchase rate is roughly 10 percentage points lower than the 20.99% charged by standard credit cards. However, the 24.99% cash advance rate is standard — avoid using this card for cash withdrawals.
Interest Savings: Why 10.99% Matters
Even small differences in interest rates add up quickly when you carry a balance.
Comparison on a $5,000 Balance
| Card | Interest Rate | Annual Interest Cost |
|---|---|---|
| Standard credit card | 20.99% | ~$1,050 |
| MBNA True Line (no fee) | 12.99% | ~$650 |
| MBNA True Line Gold | 10.99% | ~$550 |
| Savings vs. standard | ~$500/year |
After subtracting the $39 annual fee, you're still saving over $460/year compared to a standard card — and about $60/year more than the no-fee True Line.
When Does the Gold Pay for Itself?
The $39 fee is worth it if you carry an average balance of roughly $2,000 or more. Below that, the no-fee MBNA True Line Mastercard at 12.99% may be the better choice.
Insurance Benefits
Unlike most low-interest cards, the MBNA True Line Gold Mastercard includes:
- Purchase Protection — Coverage for eligible purchases against loss, theft, or damage
- Extended Warranty — Extends the manufacturer's warranty on eligible purchases
These are meaningful perks that you typically only find on mid-tier rewards cards with higher annual fees.

Comparison: Low-Interest Cards in Canada
| Feature | MBNA True Line Gold | TD Low Rate Visa | RBC Visa Classic Low Rate | MBNA True Line |
|---|---|---|---|---|
| Annual fee | $39 | $25 | $20 (1st yr free) | $0 |
| Purchase rate | 10.99% | 12.90% | 12.99% | 12.99% |
| Cash advance rate | 24.99% | 12.90% | 12.99% | 24.99% |
| Balance transfer rate | 13.99% | N/A | 12.99% | 17.99% |
| Insurance included | Yes | No | Yes | No |
| Network | Mastercard | Visa | Visa | Mastercard |
| Works at Costco | Yes | No | No | Yes |
The MBNA True Line Gold has the lowest purchase rate of the group, but the TD Low Rate Visa wins on cash advance rates (same low rate across the board). If you never take cash advances, the Gold is the best value for balance-carriers.
Drawbacks to Consider
$39 Annual Fee
This isn't a free card. If you pay your balance in full every month, the annual fee is pure cost with no rewards to offset it. Only carry this card if you regularly carry a balance.
No Rewards
Zero points, zero cash back, zero miles. The value is entirely in the low interest rate. If you pay in full monthly, a rewards card will serve you better.
High Cash Advance Rate
The 24.99% cash advance rate is no bargain. If you need cash from your credit card, consider the TD Low Rate Visa (12.90% across the board) instead.
No Balance Transfer Promo
Unlike the no-fee MBNA True Line, the Gold card doesn't offer a 0% promotional balance transfer rate. Its standard 13.99% balance transfer rate is still competitive, but if you need a short-term 0% window, the regular True Line is better.
Foreign Transaction Fee
The standard 2.5% foreign transaction fee applies. Not ideal for international purchases.
Who Is This Card Best For?
This card is an excellent choice if you:
- Carry a balance of $2,000+ and want the lowest possible purchase interest rate
- Want Purchase Protection and Extended Warranty on a low-interest card
- Shop at Costco and want a low-rate Mastercard
- Want to add family members as authorized users for free (up to 9)
- Prefer the ongoing low rate over a temporary 0% promo
It's not the best choice if you:
- Pay your balance in full every month — get a rewards card instead
- Carry a small balance under $2,000 — the no-fee True Line may be better
- Need a low rate on cash advances — consider the TD Low Rate Visa
- Want a 0% balance transfer promo — the regular MBNA True Line offers that
- Travel internationally frequently
Bottom Line
The MBNA True Line Gold Mastercard offers the lowest purchase interest rate in the MBNA lineup at 10.99% — and one of the lowest in Canada. Combined with Purchase Protection, Extended Warranty, and the ability to add up to 9 authorized users for free, it delivers meaningful value for its $39 annual fee. If you carry a balance of $2,000 or more, this card will save you more in interest than any no-fee alternative — and the included insurance is a bonus you won't find on most low-rate competitors.
