What is the Smith Manoeuvre?
Developed by Fraser Smith in 2002, the Smith Manoeuvre is a legal tax strategy that allows Canadian homeowners to convert their mortgage interest into a tax-deductible investment loan.
Unlike in the U.S., Canadians can’t directly deduct mortgage interest from their taxes. However, the Smith Manoeuvre offers a strategic workaround that could potentially save you thousands.
At its core, the Smith Manoeuvre involves borrowing against your home equity to invest in income-producing assets, making the interest tax-deductible. Think of it as turning your home into an investment engine—your mortgage gets paid down while you simultaneously build an investment portfolio.
How Does the Smith Manoeuvre Work?
Here’s a simplified breakdown:
1️⃣ Set up a readvanceable mortgage – This combines a traditional mortgage with a home equity line of credit (HELOC). As you pay down the principal, your HELOC limit increases.
2️⃣ Make your regular mortgage payment – A portion of this payment reduces the principal, freeing up HELOC room.
3️⃣ Borrow from the HELOC – You then borrow back the principal you just paid down.
4️⃣ Invest the borrowed funds – Typically in dividend stocks, ETFs, or income-generating assets.
5️⃣ Claim the HELOC interest as a tax deduction – Since the borrowed funds are used for investing, the interest on the HELOC becomes tax-deductible.
6️⃣ Use your tax refund to pay down the mortgage faster – This accelerates your mortgage paydown.
7️⃣ Repeat the cycle – Over time, you build wealth through investments while paying down your mortgage faster.

A Practical Example of the Smith Manoeuvre
Let’s say Tina, a 35-year-old software engineer, has a $600,000 mortgage at 4.5% interest. Her monthly payment is $3,320.84, of which $1,091.65 goes toward the principal.
How Tina Uses the Smith Manoeuvre:
✔ Step 1: She sets up a readvanceable mortgage.
✔ Step 2: Each month, she borrows back the $1,091.65 she just paid in principal.
✔ Step 3: She invests this money in Canadian dividend stocks.
✔ Step 4: If her HELOC rate is 6.2%, she pays $67.68 in interest that month.
✔ Step 5: At a 40% tax rate, she claims a $27.07 tax deduction.
✔ Step 6: She applies her tax refund to her mortgage, further accelerating the cycle.
Over time, Tina builds an investment portfolio while converting her mortgage interest into tax-deductible investment debt.
Benefits of the Smith Manoeuvre
✔ Tax Efficiency – Converts non-deductible mortgage interest into tax-deductible investment loan interest.
✔ Accelerated Wealth-Building – Invests regularly without affecting cash flow. You can potentially build a larger investment portfolio faster than you might otherwise.
✔ Mortgage Payoff Acceleration – Using tax refunds to pay down the mortgage, you could pay off your mortgage years earlier than scheduled.
✔ Compound Growth – Your investment portfolio has the potential to grow through compound returns over time, potentially outpacing the interest costs on your HELOC.
Potential Risks and Considerations
The Smith Manoeuvre can be a powerful way to build wealth, but it does come with risks. Here are some key ones to consider:
⚠️ Market Volatility – Your investments may not always perform well. If they underperform, you’ll still owe the debt while also facing potential losses.
⚠️ Interest Rate Risk – HELOC rates are currently 6.2% – 7%, making it harder to generate positive returns from your investments.
⚠️ Leverage Risk – Borrowing to invest magnifies both gains and losses.
⚠️ Discipline Required – Must track investments and HELOC interest properly for tax deductions.
⚠️ Cash Flow Management – While the strategy doesn’t require additional cash flow, you need to be able to handle at least the HELOC interest payments.
Common Misconceptions About the Smith Manoeuvre
As with any complex financial strategy, there are some misconceptions about the Smith Manoeuvre:
- “It’s Too Good to Be True”: While the benefits can be significant, the Smith Manoeuvre is not a get-rich-quick scheme. It’s a long-term strategy that requires careful management and comes with risks.
- “It’s Illegal or a Tax Loophole”: The Smith Manoeuvre is a legal and accepted strategy. It simply applies existing tax rules in a strategic way.
- “You Need to Be Wealthy to Do It”: While you do need home equity, the Smith Manoeuvre can be implemented by many middle-class homeowners.
- “It’s the Same as a Cash-Out Refinance”: Unlike a cash-out refinance, the Smith Manoeuvre doesn’t increase your overall debt. You’re simply restructuring your debt to make it more tax-efficient.
The Smith Manoeuvre in 2025’s Economic Climate
1. High HELOC Interest Rates (Currently at 6.2% – 7%)
- Borrowing is expensive. Even with tax deductions, the effective interest rate still ranges from 3.72% to 4.2% at a 40% tax rate.
- Safe investments won’t cut it – Dividend stocks yielding 3-4% won’t cover HELOC interest.
- For this strategy to be profitable, your investment returns must consistently exceed your after-tax borrowing cost.
2. Stock Market at All-Time Highs (S&P 500)
- Limited upside? The market continues to reach new highs, raising the risk. No one can predict where it’s headed, but with current extended valuations, the likelihood of a market correction is higher.
- Sequence risk – If the market crashes, you’re left with debt but no immediate gains.
- Uncertain interest rate policy – If central banks maintain high rates, equity returns could remain weak, while your HELOC rate continues to rise.
3. Is the Smith Manoeuvre Still Worth It?
✔ If HELOC rates drop in 2026-2027, this strategy could become more viable.
✔ Right now, it’s risky unless you’re confident your investments will outperform borrowing costs.
Alternatives to the Smith Manoeuvre
While the Smith Manoeuvre can be powerful, it’s not the only way to build wealth or manage your mortgage efficiently. Some alternatives include:
🔹 Traditional Investing – Simply investing your savings without leveraging your home equity is less risky, though potentially slower.
🔹 Accelerated Mortgage Payments – Paying down the mortgage guarantees a return equal to your mortgage rate and can provide a peace of mind.
Conclusion: Is the Smith Manoeuvre Right for You?
The Smith Manoeuvre is a sophisticated financial strategy that can accelerate wealth-building and offer significant tax benefits. To make the most of it, you need financial discipline, a long-term perspective, and a willingness to take on investment risk. In 2025’s high-interest environment, it comes with significant risks.
Who Is It Best For in 2025?
✔ Homeowners with a high risk tolerance and a long-term investment focus.
✔ Individuals comfortable with leverage and managing their finances closely.
✔ Those who anticipate lower HELOC rates in 2026-2027, making the strategy more appealing.
Who Should Be Cautious?
⚠️ Conservative investors or those who rely solely on dividends for income.
⚠️ Homeowners with tight cash flow who might struggle with higher HELOC payments in the short term.
Whether you decide to implement the Smith Manoeuvre or not, the key takeaway is to be proactive about your financial future. Consult with a financial advisor to determine if it fits your goals if needed.
