Construction Loans in Ontario

What is a construction loan in Ontario?

A construction loan in Ontario is a short-term financing product that releases funds in stages as your home is built, governed by the Ontario Construction Act which mandates a 10% statutory holdback on every payment, prompt payment timelines, and lien protections for all parties in the construction chain. Ontario is the most active new home construction market in Canada. The province's construction lending environment is shaped by several layers of regulation that directly affect how loans are structured, disbursed, and protected. The Home Construction Regulatory Authority (HCRA) licenses and regulates every builder and vendor of new homes in Ontario under the New Home Construction Licensing Act, 2017. As of February 1, 2021, all new home builders must hold a valid HCRA licence, and it is illegal to build or sell a new home without one. Lenders verify your builder's licence status through the Ontario Builder Directory before approving any construction loan. The HCRA currently licenses approximately 7,000 builders and vendors across the province. Every new home built in Ontario must be enrolled with Tarion Warranty Corporation, which administers the mandatory warranty under the Ontario New Home Warranties Plan Act. Tarion's coverage follows a 1-2-7 year structure: one year for defects in workmanship, materials, and Ontario Building Code violations; two years for defects in electrical, plumbing, and mechanical systems; and seven years for major structural defects. Effective January 1, 2026, new freehold homebuyers must complete Tarion registration within 45 days of purchase to receive full deposit protection. During the construction phase, funds are released through a draw schedule that typically includes four to five stages: foundation, framing, lockup (roof, windows, exterior sealed), interior finishing, and final completion. Before each draw, a certified inspector or appraiser visits the site to confirm the work meets Ontario Building Code standards. You pay interest only on the amount drawn, not the full loan amount. Ontario's construction lending market includes the Big 5 banks, major credit unions like Meridian Credit Union (the largest in Ontario with over 378,000 members and $28.5 billion in assets under administration), DUCA Credit Union and Alterna Savings (the third-largest credit union in Ontario), and private construction lenders. Meridian offers dedicated construction mortgage products with funds disbursed in stages throughout the build. The federal criminal interest rate cap, reduced to 35% APR as of January 1, 2025 under Criminal Code, Section 347, protects Ontario borrowers from predatory construction lending rates.

What types of construction loans are available in Ontario?

• Construction-to-permanent loans that automatically convert to a conventional mortgage after your Ontario home is complete, eliminating the need for a second loan application and saving you a second set of legal fees
• Stand-alone construction loans that fund only the building phase, with a separate mortgage application upon completion. Useful if you want to shop for the best permanent mortgage rate after the build is finished
• CMHC Progress Advance insured construction loans for Ontario borrowers with as little as 5% down payment, insured through CMHC mortgage loan insurance to reduce lender risk
• Owner-builder construction loans for Ontarians who act as their own general contractor. These carry stricter requirements and most lenders require professional project management oversight, plus confirmation that all subcontractors are properly licensed
• Urban infill and lot severance construction loans for building on subdivided lots in established Toronto, Ottawa, and GTA neighbourhoods where land values are high but lot sizes allow new builds
• Modular and prefabricated home construction loans for factory-built homes assembled on Ontario building sites. Draw schedules differ because factory stages happen off-site before delivery
• Private construction loans from Ontario-based private lenders for borrowers who do not qualify with institutional lenders. Rates start around 8% to 14% with lender fees of 2% to 6%, but approval can happen within days rather than weeks

Who qualifies for a construction loan in Ontario?

• ✓Ontario resident or Canadian citizen/permanent resident building in Ontario, at least 18 years of age with valid government-issued photo identification
• ✓Minimum down payment of 25% to 35% of total project cost for conventional construction loans, or as low as 5% through the CMHC Progress Advance program for insured loans
• ✓Good to excellent credit score, typically 680 or higher. Some lenders require 700+. Construction loans carry more risk for lenders, so credit requirements are stricter than standard Ontario mortgages
• ✓Verifiable income sufficient to cover estimated mortgage payments once the construction loan converts to a permanent mortgage, evaluated using the federal stress test rate
• ✓An HCRA-licensed Ontario builder with a valid licence under the New Home Construction Licensing Act, 2017, liability insurance, a Tarion enrollment number, and a track record of completed projects. Lenders verify the builder's licence through the Ontario Builder Directory
• ✓Complete construction plans including architectural drawings, an Ontario building permit issued under the Ontario Building Code, a detailed construction budget, and a realistic build timeline
• ✓Clear title to the building lot or a purchase agreement for the land, with an up-to-date Ontario land survey and confirmation of lot servicing (water, sewer, electrical, gas)

Construction loan rates, amounts, and terms in Ontario

Institutional construction loan rates in Ontario currently range from approximately 4.45% to 7.5% depending on the lender, your credit profile, and the loan-to-value ratio, while private construction lenders charge 8% to 14% with additional lender fees of 2% to 6%. The Bank of Canada held its policy rate at 2.25% through early 2026, keeping prime rate at 4.45% and construction loan rates at historically reasonable levels. Loan amounts for construction financing in Ontario range from $200,000 for smaller builds in rural eastern Ontario to well over $2,000,000 for custom homes in Toronto's central neighbourhoods, Oakville, or the Muskoka region. Lenders base the maximum loan amount on the lower of the total project cost or the appraised completion value, minus your required down payment. The construction period typically runs 10 to 18 months for a standard single-family home in Ontario. Complex custom builds, particularly in the GTA where permit timelines can extend, may reach 24 months. Many construction-to-permanent loans offer rate locks of 12 to 18 months for the final mortgage phase, protecting you from interest rate increases during the build. Draw schedule breakdown for a typical $600,000 Ontario construction loan: - Draw 1 (15%): Foundation complete and inspected, $90,000 released - Draw 2 (25%): Framing complete, $150,000 released - Draw 3 (25%): Lockup (roof, windows, exterior doors installed), $150,000 released - Draw 4 (20%): Interior finishing (drywall, plumbing, electrical rough-in), $120,000 released - Draw 5 (15%): Final completion and occupancy permit, $90,000 released Ontario's Construction Act requires a 10% statutory holdback on every payment in the construction chain. For a $600,000 construction loan, the lender holds back $60,000 across all draws. As of January 1, 2026, Ontario now mandates annual release of accrued holdback funds on each anniversary of the contract date, with publication of a notice of annual release required within 14 days. If no lien is filed, the holdback must be paid no earlier than 60 days and no later than 74 days after publishing the notice. Ontario HST temporary elimination on new homes (April 2026 to March 2027) Effective April 1, 2026, Ontario and the federal government are eliminating the full 13% HST on new homes valued up to $1 million for one year. Homes up to $1 million receive a full HST rebate of up to $130,000. Homes between $1 million and $1.5 million receive a flat $130,000 rebate. Homes between $1.5 million and $1.85 million receive a declining rebate from $130,000 down to $24,000. Purchase agreements must be signed between April 1, 2026 and March 31, 2027, with construction beginning by December 31, 2028. This temporary measure provides significant savings for borrowers building a new home in Ontario during this window. Ontario land transfer tax on new construction Ontario charges land transfer tax (LTT) on all property transfers including new builds. The LTT is a marginal tax with rates up to 2.5% on values over $2 million. On a $750,000 newly built home, the Ontario LTT is approximately $12,475. First-time home buyers receive a rebate of up to $4,000, reducing the tax to approximately $8,475. In Toronto, an additional municipal land transfer tax (MLTT) applies at comparable marginal rates, with first-time buyers eligible for a rebate of up to $4,475. All mortgage brokers in Ontario are licensed and regulated by the Financial Services Regulatory Authority of Ontario (FSRA) under the Mortgage Brokerages, Lenders and Administrators Act, 2006. FSRA requires full cost of borrowing disclosure, including all fees and the APR, before you sign any construction loan agreement.

Tips for getting a construction loan in Ontario

1. 1.Verify your builder's HCRA licence through the Ontario Builder Directory before signing any contract. Lenders will reject your construction loan application if your builder is not properly licensed under the New Home Construction Licensing Act, 2017
2. 2.Build a 15% to 20% contingency into your construction budget above the contractor's estimate. GTA construction costs averaged $350+ per square foot in 2025-2026, and material prices can shift between the time you budget and the time you build
3. 3.Time your purchase agreement to fall within the April 2026 to March 2027 HST elimination window if your home will be valued under $1 million. The full 13% HST rebate of up to $130,000 is a significant saving that can offset land transfer tax and other closing costs
4. 4.Confirm that your builder has enrolled the home with Tarion before construction begins. Tarion enrollment is mandatory, and without it, your warranty coverage may be incomplete or void
5. 5.Apply through Meridian Credit Union or Alterna Savings if you want Ontario-focused construction lending expertise. Meridian is the largest credit union in Ontario and offers dedicated construction mortgage products with staged disbursements
6. 6.Factor in both Ontario LTT and Toronto MLTT if building within city limits. On a $750,000 home, combined tax can exceed $20,000 even with first-time buyer rebates
7. 7.Understand the 2026 Construction Act holdback changes. The new annual release requirement means holdback funds must be released on each contract anniversary if no liens are filed, improving cash flow compared to the previous system where holdback release timing was less predictable
8. 8.Keep detailed records of every construction invoice, change order, and inspection report. Lenders require documentation at each draw stage, and Ontario Building Code inspections must be passed before draws are released
