For many Canadians, the dream of home-ownership quickly shifts to the dream of home renovation. Whether you are eyeing a dated fixer-upper or finally ready to tackle that basement suite, the critical question remains: how do you fund a major overhaul without emptying your savings or resorting to high-interest debt?

The good news is that yes, you absolutely can roll the costs of major home renovations into your mortgage in Canada. This strategy is often the most cost-effective path, allowing homeowners to leverage lower mortgage interest rates and spread the repayment over decades. However, the process isn't a simple one-step addition; it involves navigating specialized products and financial requirements.

Option 1: The Purchase Plus Improvements Program (For New Buyers)

The Purchase Plus Improvements (PPI) program is the single most popular way for Canadians buying a new property to finance renovations immediately. This option is ideal for buyers who purchase a home knowing it requires significant upgrades (kitchen, bathroom, floors, roof, etc.) before they can fully move in or enjoy the space.

How it works:

  1. Determine the Scope: You secure quotes from contractors for all proposed renovation work before the mortgage closes.

  2. Calculate the Loan: Your total mortgage amount is calculated based on the purchase price plus the approved cost of the renovations.

  3. Appraisal: The lender requires an "as-improved" appraisal, which estimates the value of the home after the renovations are complete.5 The mortgage must typically fall within the lending limits of this future value.

  4. Funding Release: The initial mortgage funds cover the purchase price, but the renovation funds are held back by the lender's lawyer. Once the renovations are fully completed (usually within 90-120 days) and inspected by a professional to confirm the work matches the quotes, the held-back money is released to pay the contractors or reimburse the borrower.

The PPI program allows you to finance your new home and its necessary extreme renovations with one competitive interest rate and a single set of payments.


Option 2: Refinancing and Equity Take-Out For Existing Homeowners willing to Home Upgrades, Mortgage, home renovations

If you already own your home and have built up equity (the difference between your home's market value and your mortgage balance), you can tap into that equity to fund your projects.


  • Mortgage Refinancing: This involves breaking your existing mortgage and replacing it with a new, larger mortgage.8 You can typically borrow up to 80% of your home’s current appraised value.9 The extra cash (the difference between the new mortgage principal and your old one) is released to you in a lump sum to pay for the renovations. This is a powerful tool for large-scale, high-cost projects, but be aware of potential prepayment penalties for breaking your current mortgage early.

  • Mortgage "Add-On" (Blend & Extend): Many lenders offer the option to "blend" your current mortgage rate with the current market rate and "extend" your amortization. This allows you to borrow additional funds for renovations without incurring the penalty of fully breaking your mortgage. This is often simpler and less costly than a full refinance.


Alternative: Home Equity Line of Credit (HELOC)


While not a true "addition" to the amortizing portion of your mortgage, a Home Equity Line of Credit (HELOC) is often secured by your home and sits "behind" your main mortgage.10 For homeowners with significant equity (often requiring 20% equity remaining after the HELOC is added), this is an excellent, flexible financing tool.


  • Flexibility: A HELOC is a revolving line of credit.11 You only pay interest on the amount you actually use, making it ideal for renovations that have unpredictable timelines or costs.

  • Access: You can borrow, repay, and re-borrow funds as needed, often up to 65% of your home's value.

  • Convenience: Unlike refinancing, a HELOC typically doesn't disrupt your primary mortgage agreement.


Key Considerations Before Committing

While adding renovation costs to your mortgage provides the lowest interest rates, it comes with important caveats:

  • Higher Overall Interest: Spreading renovation costs over a 25-year amortization means you will pay significantly more in total interest than you would with a short-term personal loan, even if the rate is lower.

  • Lender Control: With PPI and refinancing, the lender has strict control. You need detailed quotes, and the funds for renovations are often released only after the work is completed and verified, which can complicate payment schedules with contractors.13


  • Appraisal Risk: The success of the financing depends on the appraiser's estimation of the "as-improved" value. If the appraisal comes in lower than expected, the lender may reduce the amount they are willing to finance, leaving a gap you must fill.


In conclusion, Canadian homeowners have several robust options for financing their extreme renovations through their mortgage. The Purchase Plus Improvements program is perfect for new buyers, while refinancing and HELOCs serve existing owners well.14 By carefully comparing the flexibility of a HELOC against the long-term, low-rate commitment of refinancing, homeowners can choose the most prudent path to transform their property into their dream home.
