Interest-Only Mortgages in Canada: What You Need to Know - Mortgage Tips blog post featured image

Interest-only mortgages work differently in Canada than in other countries. While pure interest-only residential mortgages are rare, alternatives exist. Here's what you need to know if you're looking for lower payment flexibility.


What Is an Interest-Only Mortgage?

Definition:

  • Pay only interest for a set period
  • No principal reduction
  • Lower monthly payments during interest-only period
  • Balance remains unchanged

After interest-only period:

  • Must pay principal + interest
  • Payments increase significantly
  • May need to refinance

Availability in Canada

Traditional Interest-Only Mortgages

Reality: Very limited availability from residential lenders

Why?

  • OSFI guidelines discourage
  • Higher risk for lenders
  • Regulatory concerns

HELOC as Alternative

Home Equity Lines of Credit function similarly:

Extended amortization alternative:

  • Available from many lenders
  • Still builds equity (slowly)
  • More mainstream option
  • Maximum 30 years for uninsured

FAQ

Q: Can I get an interest-only mortgage for my primary residence?
A: Very difficult through traditional lenders. A HELOC or private lending might achieve similar results but with different terms and higher rates.

Q: Is interest-only ever a good idea?
A: For sophisticated investors with specific strategies, it can make sense. For primary residences with standard homeowners, the risks usually outweigh benefits.

Q: What happens at the end of the interest-only period?
A: You typically must begin paying principal + interest, or refinance. If you can't afford the higher payments, you may need to sell.

Q: Are interest-only payments tax-deductible?
A: Only if the borrowed funds are used for investment purposes. Interest on your primary residence is not deductible.

Q: What's the maximum interest-only period?
A: Varies by lender and product. HELOCs have no set term. Private loans often 1-3 years.
