2026 Canadian Construction Mortgage Guide: Progress Draws, Draw Inspections & Underwriting Rules
30-year amortizations on insured mortgages are now available for new construction purchases and for all first-time homebuyers — a targeted expansion from the previous 25-year maximum. (Department of Finance Canada, December 2024)
Funds released in stages, not all at once: A progress draw mortgage disburses money only as construction hits verified milestones — typically 3 to 5 draws covering foundation, framing, lock-up, drywall, and completion. This means you only pay interest on the funds already advanced, keeping your carrying costs lower during the build.
Draw inspections protect your investment: Before each draw is released, your lender will typically require an independent inspection confirming the work is complete and on budget. Understanding this process helps you coordinate with your builder and avoid holdbacks that can stall your project.
Lender holdbacks are standard — plan for them: Lenders commonly hold back 10% of each draw until the project reaches the next milestone or until a statutory lien period expires. Knowing this in advance lets you and your builder manage cash flow without surprises.
Expert Research FAQ
What are the key considerations for land acquisition, development, and construction (ADC) loans?
These exposures involve financing land acquisition for development and construction purposes, or the development and construction of residential or commercial properties.
Construction loans can be more expensive due to higher risk for the lender.
If your loan depends on future property sales, it's seen as riskier.
You might get better loan terms on a new build if you have a lot of pre-sales or a large down payment.
For taller condo projects, pre-sales are extra important; rental buildings have different rules.
When buying land to build on, a smaller mortgage (larger down payment) can help you qualify for better rates.
What documentation is required for mortgage approval in new construction?
This enables independent audits by FRFIs (federally-regulated financial institutions) and OSFI (Office of the Superintendent of Financial Institutions).
Your lender needs to keep detailed records to show they followed the rules when approving your mortgage.
You'll need to provide documents like proof of income, details about your debts, your down payment, the purchase agreement, and home insurance information.
If you have any credit issues, be prepared to explain how you're managing them and why you can still afford the mortgage.
If your mortgage is insured, the lender will keep a record confirming the insurance company's commitment.
Your lender may ask for updated information about your finances or the property, especially if something changes during the construction process.
How is property value assessed for loan-to-value (LTV) calculations during construction?
Conservative valuation is crucial in rapidly appreciating markets.
Your lender will consider factors that could affect your property's value or how easy it is to sell when calculating your loan amount.
If your local housing market is rising quickly, your lender might use a more cautious approach to estimate your property's value for your mortgage.
When you're buying a property, the lender won't usually lend you more than the actual purchase price.
Lenders can adjust property values or set loan limits to account for potential risks in property values.
Your lender has guidelines for assessing property values and will carefully review appraisals and valuation methods.
What are the LTV ratio requirements for different types of mortgages?
If your down payment is less than 20%, you'll need mortgage insurance.
With a down payment of 20% or more, you typically don't need mortgage insurance.
For higher-risk mortgages, you may need a larger down payment of at least 35%.
Higher-risk mortgages can include those where it's hard to prove your income, your credit score is low, or the property is difficult to sell.
Home equity lines of credit (HELOCs) can increase your overall debt, so lenders consider this carefully.

2026 Insured Mortgage Advantage: 5% Down Payment, Three Insurers & Best Rates Explained
Canadian homeowners and first-time buyers can achieve homeownership with down payments as low as 5% on properties priced up to $1.5 million (as of 2024) by leveraging mortgage loan insurance from Canada's three approved insurers: CMHC (Canada Mortgage and Housing Corporation), Sagen (formerly Genworth Canada), and Canada Guaranty.
