How does this happen?
Instead of only paying down low-interest debt, you safely recycle equity back into a compounding asset stream that works in parallel.

Post-Mortgage Wealth Extension: Should You Keep the Portfolio Alive?
Mortgage is paid off, HELOC stays open and interest continues, but the client never pays it out of pocket — either it capitalizes or the portfolio funds it directly.
Post-Mortgage Extension Controls
Capitalize Interest Option
The HELOC interest owed each period is added onto your HELOC balance up to the 65% LTV cap ($718,900). Once capped, spillover interest becomes an out-of-pocket payment.
Fund From Portfolio Option
The HELOC interest owed each period is automatically covered by withdrawing that amount from your invested portfolio. Your HELOC balance stays flat, but your portfolio grows a little slower since some of its returns are being used to pay the interest instead of compounding.
Post-Payoff Leverage Risk Warning
This projection assumes portfolio returns remain positive and sufficient to sustain ongoing HELOC interest. It does not guarantee future performance. A market downturn, portfolio underperformance, or HELOC rate increase could require the client to fund interest out-of-pocket, sell assets at a loss, or reduce the leveraged position. Continuing a leveraged HELOC strategy indefinitely increases risk exposure compared to paying it off. This is an illustrative scenario only and not a recommendation — consult a qualified financial and tax professional before extending or maintaining leverage after mortgage payoff.

Capital Gains Tax on Sale
See what you'd actually take home if you sold your investments in a given year, after capital gains tax.
This is added on top of the capital gain to calculate the real marginal tax impact using 2026 federal + Ontario brackets — a large gain can push part of it into a higher bracket than the client's regular income alone.
This is a simplified illustration. Calculated using 2026 federal and Ontario tax brackets, stacked on top of the entered current income. Ontario surtax is not included in this estimate. Other provinces are not yet supported. Actual Adjusted Cost Base rules (including superficial loss rules, multiple purchase lots, and dividend reinvestment plans) are more complex. Dividends may already have been taxed as income in the year received rather than as a capital gain. Consult a tax professional before making a real sale decision.
The 80% LTV & Readvancement Rule
Under Canadian regulations, the maximum combined loan-to-value limit cannot exceed 80% of property value. HELOC borrowing is strictly capped at 65% of the home value.
CRA Tax Deductibility Rule
The Canada Revenue Agency (CRA) dictates that borrowing interest is only tax-deductible when the funds are used with a "reasonable expectation of generating income".
Canadian Mortgage Compounding Rule
Unlike mortgages in the United States which compound monthly, Canadian mortgages are legally required to compound semi-annually.
Conservative Property Value Assumption
This calculator assumes a 0% home price appreciation rate. In real-world layouts, if your house value jumps, your limits organically rise cleanly as well.
Tax Refund & Portfolio Growth
Each year, the tax refund generated from your HELOC interest deduction is automatically reinvested to supercharge your compound progression stream.
Flat-Line Interest & Return Assumption
This model assumes that rates and market return vectors remain static throughout. In reality, metrics fluctuate across economic cycles.
Important Legal & Regulatory Disclosure
1. Not Financial Advice: This calculator is for educational and illustrative purposes only. It does not constitute financial, investment, or tax advice.
2. Tax Deductibility: Per CRA rules, interest is only tax-deductible if funds are used with a "reasonable expectation of generating income" (e.g., dividends or rental income). Capital gains alone do not qualify. You are solely responsible for maintaining records to prove income-producing intent.
3. Capitalized Interest: Tax deductibility of capitalized interest ("interest on interest") depends on the precise borrowing structure used. Consult a CPA to ensure compliance.
4. No Guarantees: All investment strategies involve inherent risks. Past performance or projections do not guarantee future results. Leverage (borrowing to invest) can amplify losses as well as gains.
5. FSRA Compliance: Calculations correspond to numbers supplied. Please consult with a qualified tax professional or financial advisor before implementing complex debt-leverage strategies.
6. Setup and Professional Service Costs: Although setting up and running this strategy through your readvanceable mortgage structure is designed to function with zero direct incremental costs, utilizing the services of independent financial professionals (e.g., specialized accountants, corporate tax experts, or certified financial planners) to establish, review, or file documents will incur professional service fees.
CRA Compliance & Account Setup Guide
The CRA's core rule for deductible interest is strict use-of-funds tracing (Income Tax Folio S3-F6-C1). Follow this structure carefully to preserve deductibility.
Keep Funds Separate
Never co-mingle borrowed (HELOC) funds with personal/other funds in the same account. Maintain a dedicated, separate chequing or investment account that ONLY ever receives HELOC-borrowed funds and ONLY ever pays for investments — no personal expenses, no rental deposits, no other transactions should ever pass through it. Co-mingling breaks the CRA's ability to trace borrowed funds to an income-producing use, which can invalidate the interest deduction entirely.
Where NOT to Invest Borrowed Funds
Never invest HELOC-borrowed funds inside a registered account (TFSA, RRSP, FHSA, RESP). Interest on money borrowed to invest in a registered account is NEVER tax-deductible, regardless of the investment's income potential, because registered accounts are not taxable — there is no taxable income for the interest to be traced against.
Watch for Return of Capital (ROC)
Some investments (especially certain mutual funds, REITs, and ETFs) distribute Return of Capital rather than genuine income (dividends, interest, or realized gains). ROC is not considered income for CRA deductibility purposes — if a significant portion of an investment's distributions are ROC, the interest deduction on funds used to buy that investment may be challenged. Clients should review a fund's distribution breakdown (available in its annual tax slip or fund fact sheet) before relying on it as the "income-producing" security for this strategy.
