How can I help borrowers leverage the OSFI 'straight switch' rule?

Key Points

  • The government wants to make sure banks are stable, but also lets them offer competitive mortgage rates.

  • Even if you don't need to re-qualify at a higher interest rate, your lender will still check your credit and finances.

  • Your lender will look at your income and debts carefully, considering possible changes in the economy when you renew your mortgage.

  • While there's no limit on how much you can borrow compared to your income, the lender has to manage the overall risk of their mortgages.

The OSFI 'straight switch' rule offers borrowers with existing uninsured mortgages an opportunity to potentially avoid the stress test and secure competitive rates.

For example, you with a $500k uninsured mortgage with 15 years remaining can potentially find a new lender offering a better rate without needing to requalify under the higher stress test rate.
