Buying a home is one of the biggest financial steps many Canadians take. Mortgages are usually paid down with after‑tax dollars, while investments earn interest that you can deduct on your tax return—if structured correctly. Enter the Smith Manoeuvre, a strategy that can help you convert part of your mortgage into tax‑deductible investment debt. Here’s a simple walk‑through of how it works, why people use it, and what you should watch out for.
1. What Is the Smith Manoeuvre?
At its core, the Smith Manoeuvre is a way to:
- Pay down your mortgage faster, and
- Build an investment portfolio at the same time.
It does this by “recycling” your mortgage payments into investment loans that are tax‑deductible. Normally, mortgage interest isn’t deductible, but interest on money borrowed for investments often is.
2. Why Consider the Smith Manoeuvre?
- Tax Savings
By making interest on the investment loan deductible, you could reduce your annual income tax bill. - Faster Mortgage Pay‑Down
Redirecting your tax refund into your mortgage accelerates paying down your loan. - Building Wealth
You gradually build an investment portfolio alongside paying your mortgage.
3. How Does It Actually Work?
Let’s break it down step by step:
- Re‐advanceable Mortgage
You need a special mortgage (often called a “re‑advanceable” or “readvanceable” mortgage) that combines a traditional mortgage with a line of credit. As you pay down the mortgage, the same amount becomes available in your line of credit. - Make Regular Mortgage Payments
You continue paying your regular mortgage payments. Each payment reduces your outstanding mortgage balance. - Borrow to Invest
With each mortgage payment, the line of credit limit increases by that same amount. You borrow from that line of credit to buy investments—stocks, ETFs, mutual funds, etc. - Claim the Interest Deduction
Each year, the interest you pay on your investment loan is tax‑deductible. You claim this on your income tax return, which lowers your taxable income. - Reinvest Your Tax Refund
Any refund you get from the tax deduction, you use it to make an extra lump‑sum payment on your mortgage. This further reduces your balance, frees up more credit, and the cycle continues.
4. A Simple Example
- Year 1: You owe $300,000 on your mortgage. You pay $10,000 principal.
- Your line of credit now has $10,000 available.
- You borrow $10,000 and invest it.
- Interest on that $10,000 investment loan might cost you $500 for the year. You claim that $500 on your taxes.
- The government “gives” you back, say, $150 in tax savings. You apply that $150 to your mortgage, paying down another chunk of principal.
Over time, you’ve paid down more mortgage principal (saving on non‑deductible interest) and built an investment portfolio where the loan interest is deductible.
5. Benefits—and the Catch
Pros:
- Tax‑deductible interest on your investment loan
- Potential for faster mortgage elimination
- Steady investment growth over time
- Discipline: forces you to invest consistently
Cons / Risks:
- Market Volatility: Investments can lose value, but your loan remains.
- Interest Rates: Both your mortgage rate and line‑of‑credit rate may rise.
- Complexity: You need good record‑keeping and often professional advice.
- Leverage Risk: Borrowing to invest amplifies gains—and losses.
6. Is the Smith Manoeuvre Right for You?
This strategy suits homeowners who:
- Can handle market ups and downs financially and emotionally.
- Have stable income to cover both mortgage and investment‑loan payments.
- Are comfortable with more complex tax filings.
- Plan to stay in their home long‑term (5–10+ years).
It’s not ideal if:
- You dislike investment risk.
- You have limited financial discipline.
- You plan to sell your home soon.
7. Getting Started

8. Final Thoughts
The Smith Manoeuvre can be a powerful tool to pay off your mortgage faster and grow your wealth, all while enjoying tax savings. However, it’s not a “set‑and‑forget” strategy. It requires planning, discipline, and a tolerance for market swings. If you’re curious and think it might fit your goals, chat with your mortgage broker and tax advisor to see if it’s a match for your financial journey.
