Whether you're facing a payment shock from a pandemic-era low rate or exploring your options for the first time, understanding the rules around switching lenders, qualifying ratios, and insurance programs can save you thousands. Here's what you need to know to take control of your renewal. - **Explore a 'Straight Switch' to Skip the Stress Test** If you have an uninsured mortgage and switch to another federally regulated financial institution (FRFI) without increasing your loan amount or extending your amortization period, you may be exempt from the standard stress test — also called the Minimum Qualifying Rate (MQR). This means you could qualify at your actual contract rate rather than a higher benchmark rate, potentially unlocking better deals at competing lenders without the usual requalification hurdle. - **Know Your 30-Year Amortization Options as a First-Time Buyer** As of August 2024, first-time buyers purchasing a newly built home with an insured mortgage (less than 20% down payment) became eligible for a 30-year amortization period — up from the previous 25-year maximum. This reduces your required monthly payment, improving affordability at renewal and purchase. If you're renewing an insured mortgage, confirm with your lender whether your original amortization terms affect your current eligibility. - **Understand CMHC Insurance Programs That Work for You** Canada Mortgage and Housing Corporation (CMHC) offers several programs beyond basic mortgage insurance. These include CMHC Portability (transfer your existing insurance to a new property), the CMHC Eco Plus program (partial premium refund for energy-efficient homes), and specialized programs for newcomers to Canada and self-employed borrowers. Each program has distinct eligibility criteria — ask your broker which ones apply to your situation. - **Calculate Your GDS and TDS Ratios Before You Renew** Lenders assess two key affordability ratios: your Gross Debt Service (GDS) ratio — the percentage of your gross monthly income going toward housing costs — and your Total Debt Service (TDS) ratio, which includes all debt obligations. Most lenders want to see a GDS at or below 39% and a TDS at or below 44%. Running these numbers before your renewal gives you time to pay down debt, increase income documentation, or adjust your renewal strategy. - **Understand HELOC Risks Before Your Renewal** If you have a Home Equity Line of Credit (HELOC) combined with your mortgage, be aware that OSFI requires federally regulated lenders to cap the non-amortizing HELOC portion at a Loan-to-Value (LTV) ratio of 65% or less. Any credit extended above that threshold must be structured as an amortizing loan. This rule affects how much flexible credit you can access at renewal and should factor into your overall debt management plan. ## Strategy & FAQ As a mortgage broker, the 2026 renewal wave presents both a challenge and an opportunity. Your clients need expert guidance on OSFI's straight switch exemptions, the now-active portfolio LTI (Loan-to-Income) limits affecting lender capacity, expanded 30-year amortization eligibility for insured first-time buyers, and provincial nuances — such as Quebec's notarial system, which adds distinct legal steps to the renewal and transfer process. Here's a deeper look at the strategies and regulatory context you need to advise clients with confidence. ### How can I help borrowers leverage the OSFI 'straight switch' rule? The OSFI 'straight switch' rule offers borrowers with existing uninsured mortgages an opportunity to potentially avoid the stress test and secure competitive rates. This applies when transferring an existing stand-alone, uninsured mortgage from one federally regulated financial institution (FRFI) to another, with *no increases* in the remaining contractual mortgage amortization period or the loan amount. 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. | Feature | Straight Switch | Standard Mortgage Qualification | |------------------------------|-----------------------------------------------|---------------------------------| | Minimum Qualifying Rate (MQR) | Exempt | Applied | | Loan Amount Increase | Not Permitted (except for $3,000 for fees) | Permitted (subject to approval) | | Amortization Period Increase | Not Permitted | Permitted (subject to approval) | - 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. ### What CMHC programs can benefit you, and how do they work? CMHC offers a range of mortgage loan insurance products tailored to different homeowner needs, helping more Canadians achieve homeownership. Understanding these programs allows you to provide targeted advice. For instance, CMHC Eco Plus offers a 25% premium refund for buying or building climate-friendly housing. The CMHC portability feature allows repeat CMHC insurance users to reduce or eliminate the premium payable on the new insured loan. - CMHC can help you buy a home with a smaller down payment, even if your down payment comes from multiple sources. - You can use CMHC to buy a home that needs renovations or to finance the construction of a new home. - If you're new to Canada, CMHC can help you get a mortgage, even if you're not a permanent resident. - CMHC can help self-employed individuals get a mortgage by using alternative ways to verify your income. - Get a 25% refund on your CMHC insurance if you buy or build an energy-efficient home. - You could get a 25% refund on your CMHC insurance if you spend at least $20,000 on energy-saving home improvements. - If you've used CMHC insurance before, you might save money on your next mortgage insurance premium when you move. ### How do GDS and TDS ratios impact mortgage approvals, and what can borrowers do to improve them? Gross Debt Service (GDS) and Total Debt Service (TDS) ratios are key indicators of a borrower's ability to manage debt. Lower ratios demonstrate greater affordability and increase the likelihood of mortgage approval. borrowers with high credit card debt can improve their TDS ratio by paying down those balances before applying. Understand CMHC's or other mortgage insurer's requirements regarding debt serviceability, and help borrowers understand how their debt impacts their ability to qualify. - Your GDS and TDS ratios show lenders if you can comfortably afford your mortgage and other debts. - Lenders will look at your income and debts carefully to make sure you can handle different financial situations. - When you apply for a mortgage, lenders consider current and possible future interest rate changes. - The government reviews the mortgage qualifying rate each year to ensure it's appropriate. ## Sources - OSFI exempts uninsured mortgage straight switches from the prescribed MQR and implements portfolio LTI limits — https://www.osfi-bsif.gc.ca/en/guidance/guidance-library/osfi-exempts-uninsured-mortgage-straight-switches-prescribed-mqr-implements-portfolio-lti-limits - Page 3 — https://assets.cmhc-schl.gc.ca/sf/project/cmhc/pdfs/factsheets/new/cmhc-quick-reference.pdf#page=3 - Page 2 — https://assets.cmhc-schl.gc.ca/sf/project/cmhc/pdfs/factsheets/new/cmhc-quick-reference.pdf#page=2 - Mortgage insurance — https://www.osfi-bsif.gc.ca/en/guidance/guidance-library/residential-mortgage-underwriting-practices-procedures-guideline-2017#2.5.1
