You're pre-approved. Neighbourhood selected. Realtor chosen. Then your broker asks: "Open vs closed mortgage?" and you freeze. Many first-time buyers don't realize the difference — and choosing wrong can cost you $10,000+ in penalties.
Here's the thing: this decision isn't about right or wrong. It's about matching your mortgage type to your actual plans.
Selling in two years? Different choice than settling in for ten.
What Is the Difference Between Open and Closed Mortgages?
An open mortgage lets you pay off any amount, anytime, without penalty. A closed mortgage locks you into a term (usually 1-5 years) with prepayment restrictions, but offers lower rates. According to the Canada Mortgage and Housing Corporation, most Canadian homeowners choose closed options because the rate savings outweigh the flexibility trade-off.
Open options often carry rates 1-2% higher. On a $400,000 mortgage, that's $8,000-$16,000 extra per year.
How to Save Thousands by Choosing a Closed Mortgage
A closed option locks you in for a set term. You can't exit early without paying a penalty. In return, lenders offer their best rates and predictable payments.
Terms range from six months to ten years, though five-year terms dominate. Breaking early triggers one of two penalties: three months' interest or the interest rate differential (IRD), whichever is higher. Most lenders allow annual lump-sum payments of 10-20% of your original balance, plus 10-20% increases to regular payments each year.
That's enough runway for most people to pay down principal faster without penalties.
| Feature | Open Mortgage | Closed Mortgage |
|---|---|---|
| Rate Behavior | Typically 1-2% higher than closed | Lower rates, locked for term |
| Prepayment Flexibility | Unlimited prepayments, no penalty | 10-20% annual lump-sum limit |
| Breakage Cost | $0 penalty to exit early | $15,000-$20,000+ typical penalty |
| Typical Use Case | Selling within 6-12 months | Long-term homeownership (5+ years) |
| Term Length | Usually 6 months to 1 year | 1-10 years (5-year most common) |
When Does an Open Mortgage Actually Make Sense?
You're selling soon. Your home's listed and you expect an offer within six months. Picture this: you break a closed mortgage at sale and owe $15,000 in penalties. An open mortgage with a higher rate would've cost you $2,000 extra in interest over those six months.
That's a $13,000 win.
Open mortgages also suit short-term bridge financing. Let's say you're waiting on an inheritance, selling an investment property, or expecting a work bonus large enough to pay off your balance. The Office of the Superintendent of Financial Institutions reports that only 8% of Canadian mortgages are open — most borrowers don't need the flexibility.
What Common Mistake Do First-Time Buyers Make?
Many homeowners think they need full flexibility. They imagine paying off their mortgage in three years and choose open to avoid penalties. Real talk: life changes plans.
Job loss happens. Kids arrive. Renovation budgets blow out.
A common misconception is that closed mortgages trap you. They don't. The 10-20% annual prepayment allowance lets you chip away faster without penalties. On a $400,000 mortgage, you can pay an extra $40,000-$80,000 per year toward principal — enough for most accelerated strategies.
If you're not certain you'll sell or pay off the balance within a year, closed is almost always cheaper.
How to Choose Between Open and Closed in 2026
Start with your timeline. Staying put for five years or more? Closed wins every time. Selling within 12 months? Open saves you penalty pain.
Next, check your cash flow. Can you handle a payment that's $300-$600 higher per month? That's the typical cost of an open rate. Run the numbers with your broker before committing.
If you're unsure, ask about a convertible mortgage. It's a hybrid that starts open but lets you lock into a closed rate anytime without penalty. You pay slightly more than a closed rate but less than a fully open one — ideal if your plans might shift.

Frequently Asked Questions
Can I switch from closed to open mid-term?
No, you can't switch without breaking your current mortgage and paying the penalty. Some lenders offer convertible mortgages that let you lock into a closed rate anytime without penalty fees.
How much does breaking a closed mortgage cost?
Most Canadians pay $15,000-$20,000 to break a five-year fixed closed mortgage early. The penalty is either three months' interest or the interest rate differential calculation, whichever is higher.
Do open mortgages qualify for the same CMHC programs?
Yes, both open and closed mortgages qualify for CMHC insurance if you're putting down less than 20%. The insurance premium (1.8-4% of your loan) is the same regardless of mortgage type.
