Mortgage Prepayment Privileges in Canada (2026): How to Save Years and Tens of Thousands

Most Canadian homeowners know they can pay off their mortgage faster — but very few use the prepayment tools they are already paying for. In 2026, used properly, prepayment privileges can save the average GTA homeowner $60,000-$120,000 in interest and shave 5-10 years off the amortization. Here is exactly how they work.

The Three Tools You Already Have

Every standard Canadian mortgage gives you three prepayment tools:

1. Annual lump sum — pay extra against principal once a year (or on each anniversary)
2. Payment increase — permanently raise your regular payment
3. Double-up / extra payment — make an extra scheduled payment whenever you want

The percentages vary by lender. The two common standards in 2026 are:

Most monoline lenders (MCAP, First National, Strive, RFA) and the major banks now offer at least 15/15 on standard fixed and variable mortgages.

Tool 1 — Annual Lump-Sum Payments

You can pay up to 15% (or 20%) of the original mortgage amount as a lump sum each year, with no penalty. The full amount goes against principal.

Example. Original $500K mortgage with 15% annual privilege:

• Maximum lump sum per year = $75,000
• You can use it every year, or skip years
• Most lenders allow it on the anniversary or at any time during the year

Real-dollar impact. A $10,000 annual lump sum on a $500K, 25-year, 4.30% mortgage:

• Years saved: ~7
• Interest saved: ~$72,000

A $20,000 annual lump sum on the same mortgage:

• Years saved: ~11
• Interest saved: ~$108,000

Tool 2 — Permanent Payment Increase

You can permanently raise your regular monthly (or bi-weekly) payment by up to 15% (or 20%) per year. Once raised, the new amount becomes the new minimum.

Example. Original payment $2,710/mo on a $500K mortgage at 4.30%/25-year. A 15% increase = $315/mo extra → new payment $3,025/mo.

Real-dollar impact:

• Years saved: ~5
• Interest saved: ~$48,000

The beauty here is that it is automatic — once you set it, you don't have to remember to do anything else. For people who struggle with discipline, this is the most powerful tool.

Tool 3 — Double-Up / Extra Payments

Many lenders let you make extra scheduled payments at any time (e.g. "double up" on a payment). These extra payments go fully against principal.

This is the most flexible tool — useful for tax refund money, a bonus, or a windfall.

The Sneaky Free One — Accelerated Bi-Weekly Payments

This is not technically a "prepayment" but it is the cheapest mortgage acceleration in Canada.

• Standard monthly payment = (annual interest + principal) ÷ 12
• Accelerated bi-weekly = monthly payment ÷ 2, paid every 2 weeks → 26 payments per year = effectively 13 monthly payments per year

You make one extra monthly payment per year without noticing.

Real-dollar impact on a $500K, 25-year, 4.30% mortgage:

• Years saved: ~3
• Interest saved: ~$32,000

This is free money. If you are not on accelerated bi-weekly, switch today.

Stacking the Tools

The compounding effect is significant. If you do all three:

Everything above assumes a $500K, 25-year, 4.30% mortgage at origination.

Watch-Outs

1. The "original amount" rule. Lump sums are calculated on the original mortgage amount, not the current balance. So 15% of a $500K original mortgage is $75K every year, even when your balance is $300K.
2. Calendar year vs. anniversary. Some lenders reset on the calendar year; others on the mortgage anniversary. A $20K lump in December and another in January often counts as one year's allowance, not two — check your terms.
3. Restricted "no-frills" mortgages sometimes have 0% prepayment. Always check before accepting a "rate special."
4. Variable mortgages with static payments can be increased — and should be, if you are anywhere near the trigger rate.
5. Lump sums during a fixed term still count toward your annual privilege; they do not trigger an IRD penalty as long as you stay under the cap.
