Convert your bad debt into tax-deductible good debt.
The core concept of the Smith Manoeuvre is simple: In Canada, interest on a mortgage for your personal home is NOT tax-deductible. However, interest on a loan used to buy income-producing investments IS tax-deductible.
Because an AIO is a readvanceable mortgage, every time your fluctuating cash flow pays down your principal, your available credit limit increases. This strategy involves immediately re-borrowing a safe percentage of that newly created equity to invest. Over time, your "bad" non-deductible debt shrinks, your "good" tax-deductible debt grows, and your wealth compounds.
Based on your specific simulator setup, your mortgage will reach zero (or Net Zero) in X Years. We have mapped out the exact, fluctuating principal paydowns from your simulation. Adjust the parameters below to see the impact of re-borrowing that equity over your specific timeline.
Doing nothing but paying off the house.
Home Equity Built (X Yrs)
Re-borrowing equity to invest.
Net Wealth Added (X Yrs)
*This model follows your exact, fluctuating yearly principal paydown from the simulator. It assumes tax refunds and dividends are reinvested annually. Net Wealth Added = (Home Equity + Investment Portfolio) - Investment Loan. It does not account for capital gains tax upon final sale.
Leverage amplifies your wealth when the market goes up, but it violently amplifies your losses when the market crashes. This is why the Re-Borrow Limit is your most critical safety net.
If you borrow 100% of your available equity and the stock market drops 30%, your portfolio value plummets, but your loan balance remains exactly the same. You now owe the bank more money than your investments are worth. By keeping your Re-Borrow Limit lower (e.g., 60-80%), you create a "shock absorber" so a crash doesn't wipe out your net worth.
Your AIO borrowing rate is variable. If the Bank of Canada raises interest rates significantly, the carrying cost of your investment loan spikes. If your dividend yields remain flat while your interest costs double, you will have to pay the difference out of your own pocket every month, bleeding your household cash flow dry.
