Canada Housing Policy Update: Key Changes in 2027

Key federal housing policy changes affecting mortgages and housing in 2027: (1) 30-year amortization for insured mortgages: Extended to first-time buyers of new construction and all buyers of new construction properties (announced August 2024, effective August 2024). This increases purchasing power by reducing monthly payments vs 25-year amortization; (2) CMHC insurance limit increase: Maximum insured mortgage purchase price raised from $1M to $1.5M (December 2024). Allows high-ratio mortgage insurance on properties previously requiring 20%+ down; (3) Home Buyers' Plan enhancement: RRSP withdrawal limit for first homes increased to $60,000 per person ($120,000/couple) from prior $35,000; (4) FHSA full deployment: First Home Savings Account now in full operation — up to $8,000/year, $40,000 lifetime, tax-deductible contributions and tax-free withdrawals for qualifying first home purchase; (5) Federal housing accelerator: Infrastructure funding linked to municipal zoning reform — cities receiving funding must allow higher density near transit. See Canada new mortgage rules 2027 and CMHC homebuyer resources.

The OSFI B-20 stress test requires mortgage applicants to qualify at the greater of their contract rate + 2%, or 5.25% (the floor rate). Key 2027 developments: (1) Uninsured mortgage switches: OSFI's 2022 amendment allowing lenders to waive the stress test for straight switches (same balance, same amortization) to a new federally regulated lender at renewal remains in place. This reduces the captive lender problem; (2) Stress test floor rate: The 5.25% floor remains unchanged as of 2027. With most contract rates above 5%, the floor is not binding — qualifying rate = contract rate + 2% in most cases; (3) Insurance vs. uninsured: CMHC-insured mortgages (under 20% down) also apply the stress test — administered through lender underwriting; (4) Potential reform pressure: There has been ongoing political discussion about whether the stress test is too restrictive in a higher-rate environment. As of 2027, OSFI has not changed the methodology. Read the full stress test glossary and OSFI B-20 guidelines.

Provinces are legislating housing supply changes to address affordability: Ontario: Bill 185 (Cutting Red Tape to Build More Homes Act, 2024) streamlined development approvals and limited appeal rights. Municipalities required to allow up to three residential units on most lots (existing home + secondary suite + laneway/garden suite); British Columbia: Bill 44 (2023) requires all single-family zones in municipalities over 5,000 population to allow small-scale multi-unit (up to 4 units on most lots, 6 on transit corridors). Implemented in phases through 2024–2025; Alberta: Provincial review of municipal zoning rules to reduce red tape; secondary suite rules relaxed in Calgary and Edmonton; Quebec: Focus on social and affordable housing construction funding through the SHQ (Société d'habitation du Québec). These changes affect property values, what you can build, and how lenders assess properties. See Canada secondary suite mortgages and CMHC Housing Observer reports.

The expanded 30-year insured amortization (available to first-time buyers and new construction) increases affordability by reducing monthly payments: Example: $550,000 mortgage at 5.5%. 25-year amortization: $3,386/month P+I. 30-year amortization: $3,120/month P+I. Monthly savings: $266/month. This lower monthly payment improves GDS/TDS ratios, allowing buyers to qualify for a larger mortgage or qualify more easily at a given price. Trade-off: significantly more total interest paid. Same mortgage over 30 years pays approximately $123,000 more in interest than the 25-year option. The 30-year option also builds equity more slowly in the early years — a risk if values fall. Lenders are applying the stress test to the 30-year amortization. CMHC insurance premiums are unchanged regardless of amortization (premiums based on LTV). See Canada amortization reform 2027, the amortization glossary, and CMHC mortgage insurance overview.

CMHC mortgage insurance updates through 2025–2027: (1) Purchase price limit $1.5M: Insured mortgages now available on properties up to $1.5M (from $1M). Min 5% down on first $500K, 10% on amount above $500K (standard rules). Allows buyers in high-price markets (Toronto, Vancouver) to access insured products they were previously excluded from; (2) Premium rates unchanged: Standard premium tiers (0.60%–4.00% of mortgage amount) remain the same; (3) MLI Select (multi-residential): Continues to offer premium incentives for affordable and energy-efficient rental developments; (4) Secondary suite income: Enhanced treatment of secondary suite rental income for qualifying purposes (see Canada secondary suite guide); (5) Refinance limit: High-ratio refinance (over 80% LTV) still not eligible for CMHC insurance — maximum insured refinance is 80% LTV; (6) Sagen and Canada Guaranty: Private insurers continue operating alongside CMHC with similar rules. See CMHC insurance glossary and CMHC insurance guide.

The Bank of Canada's overnight rate directly affects variable-rate mortgages and indirectly influences fixed rates: (1) Variable-rate holders: Each 0.25% BoC rate cut reduces the prime rate by 0.25% — for a $500,000 variable mortgage, that is approximately $100/month savings. BoC cut rates through late 2024 and into 2025; the pace of cuts in 2027 depends on inflation trajectory; (2) Fixed-rate mortgages: Tied to Government of Canada bond yields (especially 5-year GoC bonds) — do not move directly with BoC rate changes. Bond yields respond to BoC expectations but also global factors; (3) Renewal shock: Borrowers who took 5-year fixed mortgages in 2020–2022 at 1.5–2.5% are renewing in 2025–2027 at 4.5–5.5%+ — monthly payments increasing 30–50%. OSFI reports the "renewal wall" as the key household financial risk; (4) Variable vs. fixed decision 2027: If BoC rate cuts continue, variable rates will fall further. The fixed-variable decision depends on your rate outlook and risk tolerance. See Canada variable rate mortgage 2027 and the Bank of Canada monetary policy page.
