What are Loan-to-Income (LTI) limits and how will they affect institutional mortgage portfolios?

OSFI is introducing Loan-to-Income (LTI) limits to reduce risks from high household debt in institutional mortgage portfolios .

These limits, which take effect in fiscal Q1 2025, apply to portfolios, not individual borrowers.

Key Points

  • New rules limit how much risk lenders can take on their overall mortgage business.

  • These changes won't directly affect your ability to get a mortgage or renew your existing mortgage.

  • Lenders are expected to follow these new rules starting in early 2025.

  • The government will keep an eye on how well these limits are working.

  • The government may rethink the mortgage stress test after these new rules are in place, as they both aim to ensure responsible lending.
