OSFI's Guideline B-20 sets maximum (/glossary/loan-to-value) ratios and amortization expectations that may limit your renewal options depending on your lender's portfolio composition.

  • Lenders must maintain average amortization periods below their stated maximums across their entire portfolio
  • Maximum LTV ratios vary by loan type: conventional mortgages, non-conforming loans (80% max), and HELOCs (80% max, with 65% max on the revolving credit portion)
  • Lenders must regularly review and update their LTV frameworks based on market conditions

Your lender may be more restrictive on amortization extensions if their portfolio average is approaching limits. Non-conforming borrowers face stricter 80% LTV limits, and HELOCs are generally limited to 65% LTV on the credit line portion, but combined mortgage and HELOC LTV can be up to 80%.

Understand your current (/glossary/loan-to-value) ratio and how it affects your renewal options. If you have a HELOC combined with your mortgage, be aware of the 65% LTV limit on the credit line portion, but the total combined mortgage and HELOC LTV can be up to 80%.

HELOC LTV Restrictions HELOC portion limited to 65% LTV, but total combined mortgage and HELOC LTV can be up to 80%
