How Some Kelowna Homeowners Are Making Their Mortgage Tax-Deductible

Michael A. Jones – PREC* | Royal LePage Kelowna

Mortgage interest isn’t tax-deductible in Canada — unless you use a financial strategy called The Smith Manoeuvre™. Originally developed by Fraser Smith, this approach has helped some Canadian homeowners gradually convert their mortgage debt into tax-deductible investment loans.

If you're a homeowner in Kelowna or anywhere in the Okanagan, and you're curious about how to make your mortgage work harder for you, this is something worth knowing — with caution.

What Is the Smith Manoeuvre?

According to Investopedia, the Smith Manoeuvre involves borrowing back the principal you pay down on your mortgage and investing it. Over time, this converts your non-deductible mortgage interest into deductible investment loan interest.

How It Works — The Role of a Readvanceable Mortgage

The Smith Manoeuvre depends on a specific type of loan setup called a readvanceable mortgage. This is a product that combines a traditional mortgage with a home equity line of credit (HELOC). As you pay down the mortgage principal, your HELOC limit increases by the same amount.

Here’s a simplified step-by-step breakdown:

1. Start with a Readvanceable Mortgage: Each mortgage payment you make reduces your principal — which automatically increases the amount available to borrow through your HELOC.
2. Re-Borrow from the HELOC to Invest: After every payment, you borrow back the paid-down principal (via the HELOC) and invest it in income-generating assets like dividend stocks, REITs, or funds.
3. Claim Tax Deductions: Because the borrowed money is used for investments that generate income, the interest on the HELOC becomes tax-deductible under CRA rules.
4. Use Tax Refunds to Pay Down the Mortgage Faster: You can apply your tax refund to accelerate mortgage payments — which increases your HELOC room — and repeat the cycle.

This process gradually converts your mortgage into an investment loan with tax-deductible interest, while also building a portfolio of income-generating assets. However, it requires discipline, proper financial planning, and the ability to manage leverage over time.
