What is a construction loan?

**A construction loan is a short-term financing product that funds the building of a new home or major renovation in stages, releasing money at each construction milestone rather than in a single lump sum.** This structure, called a **draw schedule**, protects both the borrower and the lender by ensuring funds match actual construction progress. Construction loans in Canada work differently from conventional mortgages. Instead of receiving the full loan amount at closing, borrowers receive funds in a series of draws that typically align with five construction stages: foundation, framing, lockup (exterior sealed), interior finishing, and final completion. A professional appraiser or inspector verifies completion of each stage before the next draw is released. During the construction period, borrowers make **interest-only payments** on the amount already drawn. For example, if your total construction loan is $500,000 but only $100,000 has been drawn after the foundation stage, your monthly interest payment is calculated on $100,000 only. This keeps payments manageable while your home is being built. The Financial Consumer Agency of Canada (FCAC) requires all federally regulated lenders to provide full cost of borrowing disclosure before a construction loan agreement is signed ([FCAC: Cost of Borrowing](https://www.canada.ca/en/financial-consumer-agency/services/rights-responsibilities/rights-clear-disclosure.html)). Provincial regulators enforce similar requirements for credit unions and private lenders. Once construction is complete, the loan converts to a conventional mortgage through a process called a **completion mortgage** or takeout mortgage. This conversion can happen automatically with the same lender or require a new application with a different lender, depending on the original loan terms. Canada Mortgage and Housing Corporation (CMHC) offers the **Progress Advance** program, which allows CMHC-insured construction loans for borrowers with as little as 5% down payment on properties valued under the insured mortgage threshold ([CMHC: Progress Advance](https://www.cmhc-schl.gc.ca/professionals/project-funding-and-mortgage-financing/mortgage-loan-insurance/mortgage-loan-insurance-homeownership/cmhc-progress-advance)). Without CMHC insurance, most lenders require 25% to 35% down payment on the total project cost.

Types of construction loans available in Canada

Construction-to-permanent loans that automatically convert to a conventional mortgage after the build is complete, saving you from applying for a second loan
Stand-alone construction loans that fund only the building phase, requiring a separate mortgage application upon completion. Useful if you want to shop for the best mortgage rate after the build
CMHC Progress Advance insured construction loans for borrowers with as little as 5% down payment, available through approved lenders for properties within the insured mortgage value limit
Owner-builder construction loans for borrowers who act as their own general contractor. These carry stricter requirements because lenders view owner-builds as higher risk
Renovation construction loans for major structural renovations that go beyond cosmetic updates, such as additions, gut renovations, or converting a property type
Modular and prefabricated home construction loans for factory-built homes assembled on-site. Draw schedules differ because factory stages happen off-site before delivery
Rural and cottage construction loans for building on non-urban lots, including waterfront and recreational properties

Who qualifies for a construction loan in Canada?

✓Canadian citizen or permanent resident, at least 18 years old (19 in British Columbia, Nova Scotia, and New Brunswick)
✓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. Construction loans carry more risk for lenders, so credit requirements are stricter than standard mortgages
✓Verifiable income sufficient to cover the estimated mortgage payments once the construction loan converts to a permanent mortgage
✓Approved builder or general contractor with valid provincial licensing, liability insurance, and a track record of completed projects. Most lenders maintain a list of approved builders
✓Complete construction plans including architectural drawings, building permits, 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 land survey

Construction loan rates, amounts, and terms in Canada

**Construction loans in Canada typically carry interest rates 0.5% to 1.5% higher than conventional mortgage rates, with current construction loan rates ranging from approximately 5.5% to 8.5% depending on the lender, your credit profile, and the loan-to-value ratio.** Rates are variable during the construction period and fixed options become available at conversion to a permanent mortgage. Loan amounts for construction financing range from $100,000 for small builds to over $2,000,000 for custom homes in high-cost markets like Vancouver and Toronto. Lenders base the maximum loan amount on the lower of the total project cost or the appraised value of the completed home, minus your required down payment. The construction period typically runs 6 to 18 months, though complex custom builds can extend to 24 months. Most lenders set a maximum construction period in the loan agreement and charge penalties or require refinancing if the build exceeds the timeline. **Draw schedule breakdown for a typical $500,000 construction loan:** - Draw 1 (15%): Foundation complete, $75,000 released - Draw 2 (25%): Framing complete, $125,000 released - Draw 3 (25%): Lockup (roof, windows, exterior doors), $125,000 released - Draw 4 (20%): Interior finishing (drywall, plumbing, electrical), $100,000 released - Draw 5 (15%): Final completion and occupancy permit, $75,000 released Lenders typically hold back 10% to 15% of each draw as a **holdback** to protect against builder liens. Provincial lien legislation, such as Ontario's Construction Act, mandates specific holdback percentages and release timelines ([Ontario Construction Act](https://www.ontario.ca/laws/statute/90c30)). The Bank of Canada's policy rate directly influences construction loan rates. When the overnight rate rises, variable-rate construction loans adjust accordingly ([Bank of Canada: Key Interest Rate](https://www.bankofcanada.ca/core-functions/monetary-policy/key-interest-rate/)). Be cautious of lenders who quote low rates without disclosing inspection fees, draw administration fees, or legal costs. A responsible lender provides a complete cost breakdown before you commit.

Pros and cons of construction loans

Pros

+ Pay interest only on the amount drawn during construction, keeping your carrying costs lower than a full mortgage payment while the home is being built
+ Progressive draw structure ensures your money funds actual construction progress, reducing the risk of overpaying a builder upfront
+ Build a home customized to your needs and preferences instead of compromising on an existing property
+ CMHC Progress Advance program makes construction accessible with as little as 5% down for qualifying borrowers
+ Construction-to-permanent loans convert automatically to a mortgage, avoiding the cost and effort of a second loan application

Cons

- Higher interest rates than conventional mortgages because construction carries more risk for lenders, including cost overruns, builder defaults, and market changes
- Larger down payment required (25% to 35%) for conventional construction loans compared to 5% to 20% for a standard home purchase
- Cost overruns are common in construction. If your build goes over budget, you may need additional financing at potentially unfavorable terms
- Longer and more complex approval process. Lenders evaluate your finances, the builder, the construction plans, and the land before approving
- Builder delays can extend the construction period, increasing your total interest costs and potentially triggering loan extension fees

Tips for getting a construction loan in Canada

1.Get your builder approved by the lender before finalizing your construction contract. Lenders require builders to carry proper licensing, liability insurance, and a clean track record. A rejected builder can delay your project by months
2.Build a 15% to 20% contingency into your construction budget above the contractor's estimate. Cost overruns are the norm, not the exception, in residential construction. Having a buffer prevents the need for emergency financing mid-build
3.Lock in your permanent mortgage rate as early as possible. Many lenders offer rate holds of 120 to 180 days. If your build finishes within that window, you keep the rate even if market rates rise
4.Understand the draw schedule before signing. Know what percentage is released at each stage, what inspection is required, and how long the release takes after each inspection approval
5.Compare the CMHC Progress Advance program against conventional options. The lower down payment is attractive, but CMHC mortgage insurance premiums add to your total cost. Run both scenarios to see which is cheaper overall
6.Verify that your building lot is ready for construction. Confirm zoning, building permits, site servicing (water, sewer, electricity), and any environmental assessments are complete before applying. Lenders will not release funds until all permits are in place
7.Keep detailed records of every construction invoice, change order, and inspection report. Lenders require documentation at each draw, and organized records make the process smoother
8.If you are an owner-builder, expect stricter scrutiny. Lenders will require detailed proof of your construction knowledge and may set a lower loan-to-value ratio. Professional project management is strongly recommended

Protecting yourself during the construction lending process

**Construction projects involve large sums of money dispersed over months, which creates unique risks that borrowers should manage proactively.** Understanding your rights and obligations throughout the process protects you from financial loss. All Canadian provinces have construction lien legislation that protects you if a subcontractor or supplier is not paid by your general contractor. These laws require lenders to hold back a percentage of each draw (typically 10%) to cover potential lien claims. In Ontario, the Construction Act mandates a 10% holdback for 60 days after substantial completion ([Ontario Construction Act](https://www.ontario.ca/laws/statute/90c30)). British Columbia's Builders Lien Act has similar provisions. The FCAC requires lenders to provide complete cost of borrowing disclosure for construction loans, including all fees, the interest calculation method, and the terms of conversion to a permanent mortgage ([FCAC: Mortgages](https://www.canada.ca/en/financial-consumer-agency/services/mortgages.html)). If your lender does not provide this disclosure in writing, do not proceed. Before signing a construction loan agreement, have an independent real estate lawyer review the terms. Pay particular attention to the conversion clause (how and when the loan converts to a mortgage), the extension policy (what happens if construction takes longer than planned), and any cost overrun provisions. If your builder goes bankrupt during construction, your lender's holdback provides some protection, but it may not cover all costs. Verify that your builder carries proper surety bonds or new home warranty coverage. In Ontario, Tarion provides mandatory new home warranty coverage ([Tarion](https://www.tarion.com/)). Other provinces have similar programs. For free guidance on managing mortgage-related decisions, contact the FCAC at 1-866-461-3222 or visit their mortgage resources online. If you need independent financial advice, certified non-profit credit counsellors through Credit Counselling Canada can help evaluate whether a construction project fits your financial situation.

Frequently asked questions

What is a construction loan?

**A construction loan is short-term financing that funds the building of a new home or major renovation through a series of staged draws rather than a single lump sum.** Each draw is released after a professional inspector verifies that the corresponding construction milestone is complete. During the build, you pay interest only on the amount drawn. After construction, the loan converts to a standard mortgage.

How much down payment do I need for a construction loan in Canada?

**Most conventional construction loans require 25% to 35% of the total project cost as a down payment.** However, the CMHC Progress Advance program allows as little as 5% down for insured construction loans on properties within the insured mortgage limit. Your down payment amount directly affects your interest rate and available lender options.

What is a draw schedule?

**A draw schedule is the plan that defines when and how much money is released from your construction loan at each building stage.** A typical draw schedule has five stages: foundation (15%), framing (25%), lockup (25%), interior finishing (20%), and final completion (15%). Before each draw, a professional inspector or appraiser visits the site to confirm the work meets the required standard.

Are construction loan rates higher than mortgage rates?

**Yes, construction loan rates are typically 0.5% to 1.5% higher than conventional mortgage rates.** The premium reflects the higher risk construction projects carry for lenders, including potential cost overruns, builder defaults, and market fluctuations during the build period. Current construction loan rates in Canada range from approximately 5.5% to 8.5%.

Can I act as my own builder with a construction loan?

**Yes, but options are limited and requirements are stricter.** Owner-builder construction loans require you to demonstrate significant construction knowledge or experience. Lenders typically require a lower loan-to-value ratio (meaning a larger down payment), more detailed project documentation, and professional oversight from an architect or project manager. Fewer lenders offer owner-builder loans compared to standard construction loans.

What happens if my construction goes over budget?

**If your build exceeds the original budget, you need to cover the difference from your own funds or apply for additional financing.** This is why a 15% to 20% contingency buffer is recommended. Lenders will not automatically increase your construction loan. If you cannot fund the overrun, construction may stop, which creates significant financial and legal complications.

How does the CMHC Progress Advance program work?

**CMHC Progress Advance allows approved lenders to release insured mortgage funds in stages during construction, with borrowers contributing as little as 5% down.** The program covers new construction of 1 to 4 unit homes. Your lender applies for CMHC insurance, and draws follow a predetermined schedule with inspections at each stage. CMHC charges a mortgage insurance premium that is added to your loan balance.

What happens after construction is complete?

**Your construction loan converts to a permanent mortgage, either automatically or through a new application, depending on your loan terms.** With a construction-to-permanent loan, conversion happens automatically at the agreed-upon rate. With a stand-alone construction loan, you apply for a separate mortgage. The final appraised value of the completed home determines your loan-to-value ratio and available rates.

Do I need a licensed builder to get a construction loan?

**Most lenders require a licensed general contractor with valid provincial registration, liability insurance, and a demonstrated track record.** Lenders often maintain an approved builder list. If your preferred builder is not on the list, the lender will review their credentials, financial stability, and history of completed projects before granting approval.

How long does it take to get approved for a construction loan?

**Construction loan approvals typically take 4 to 8 weeks because lenders evaluate multiple factors beyond your personal finances.** The lender reviews your income, credit, and debt ratios, plus the construction plans, building permits, the builder's credentials, the land appraisal, and the projected value of the completed home. Having all documentation ready before applying can shorten the timeline.

Can I get a construction loan for a cottage or vacation property?

**Yes, several Canadian lenders offer construction loans for recreational and cottage properties.** Requirements are generally similar to primary residence construction loans, but lenders may require a larger down payment (30% to 40%) because secondary properties carry higher default risk. Rural and waterfront properties may also require specialized appraisals.

What provincial regulations affect construction loans?

**Each province has construction lien legislation that affects how your loan funds are released and protected.** Ontario's Construction Act requires a 10% holdback on all construction payments. British Columbia's Builders Lien Act has similar holdback requirements. Provincial building codes set the inspection standards that must be met before each draw is released. New home warranty programs, like Tarion in Ontario, provide additional buyer protection.
