Building a home from the ground up is one of the most exciting and rewarding experiences, but navigating the financial side of construction can sometimes feel overwhelming. That’s where a construction mortgage comes in.

Unlike a traditional mortgage, which provides the full loan amount upfront, a construction mortgage distributes funds in stages, aligning with the progress of your build. This approach allows Canadians to finance new constructions or major renovations without bearing the full financial burden at once.

In this blog, we’ll dive into what a construction mortgage is, how it works in Canada, the criteria for approval, and why partnering with an experienced mortgage broker can simplify the entire process, helping you turn your dream home into reality with confidence and ease.

What Is a Construction Mortgage?

For individuals planning to build a home or undertake a major renovation, a construction mortgage offers a flexible financing solution. Unlike a conventional mortgage, the lender does not provide the whole amount up front. Instead, funds are released progressively in stages, known as “draws,” as the construction reaches specific milestones.

This staged approach protects both the lender and the borrower, while giving homeowners greater control over costs throughout the building process.

How Does a Construction Mortgage in Canada Work?

Knowing the draw process is key to understanding how a construction mortgage works. Typically, the process works as follows:

1. Schedule of Draws

Lenders release funds in phases, including:

  • Acquisition of land or foundation completion.
  • Phase of lock-up, i.e., roof, doors, windows.
  • Finishing inside.
  • Finalization.

Every lender will employ somewhat distinct phases, but all have a planned release strategy.

2. Inspections Before Every Draw

Before disbursing funds, a lender-approved inspector inspects the construction site to verify progress. This guarantees the project stays within budget and on track.

3. Payments of Interest Only While Under Construction

Borrowers only pay interest on the amount drawn, not on the entire mortgage. Managing cash flow during the construction process is aided by this, which is particularly helpful for paying for temporary housing or rent.

Construction Mortgage in Canada: Key Requirements

Because construction mortgages carry a higher risk, lenders typically require more documentation than they would for a standard mortgage.

Common requirements for a construction mortgage include:

1. 20–25% Down Payment

Lenders often demand a larger down payment, typically between 20% and 25%, because construction projects have ambiguity.

2. Detailed Building Plans and Budget

You have to give:

  • Architectural sketches.
  • Specifications of materials.
  • Complete budget break.
  • Timeline for construction.

This enables lenders to evaluate expected expenditures and feasibility.

3. Licensed Builder or Contractor

Most lenders want, or demand, a certified contractor with a demonstrated track record. Some could enable self-builds, but under more rigorous conditions.

4. Evidence Of Income And Credit That Is Solid

Like any mortgage, lenders have to confirm:

  • Consistent income.
  • Solid credit score.
  • Low debt-to-income ratio.

5. Authorization and Insurance

You must offer evidence of necessary permits and adequate building insurance, including liability and builder’s risk insurance.

Construction Mortgage vs Standard Mortgage

Although both loans assist with property funding, they run very differently.

Construction Mortgage

  • Funds are distributed incrementally, in stages or “draws.”
  • Interest-only payments are made during the construction stage.
  • Requires additional documentation due to higher risk.
  • Designed for new builds or major renovation projects.

Traditional Mortgage

  • The full loan amount is released as a lump sum at closing.
  • Full mortgage payments start immediately after closing.
  • Standard documentation similar to typical home loans.
  • Typically used for existing, fully constructed homes.

Advantages of a Construction Mortgage

For Canadian homeowners, selecting a construction mortgage offers a number of benefits:

1. Totally Alter Your Home

You have total say over design, layout, finishing, and materials.

2. Interest is Paid Only on the Funds Used

With a construction mortgage, you only pay interest on the amount that has been drawn so far, not on the full mortgage. This helps reduce upfront costs during the building phase.

3. More Authority over Schedule and Budget

You have better control over costs and project goals since money is distributed over phases.
