The Smith Maneuver is a Canadian financial strategy that converts your non-deductible mortgage interest into tax-deductible investment loan interest. Here's the 3-step principle:
- Step 1: Each mortgage payment includes a principal portion. That principal repaid frees up room on your home equity line of credit (HELOC).
- Step 2: You immediately re-borrow that amount from the HELOC and invest it in income-producing assets (Canadian dividend stocks, ETFs, etc.).
- Step 3: The interest paid on that HELOC portion is tax-deductible under CRA rules, since the borrowed money is used to earn investment income. You get an annual tax refund + you build a portfolio.
✓ 100% legal in Canada — CRA rules on interest deductibility (Bulletin IT-533).
The 20% rule in Canada — why it's critical
To execute the Smith Maneuver, you need a home equity line of credit (HELOC) — typically through a readvanceable mortgage. And in Canada, to qualify for this type of product, you must respect two rules set by the Office of the Superintendent of Financial Institutions (OSFI):
- Minimum 20% equity: Your home value minus your mortgage balance must be at least 20% of your property value. Without 20% equity, no bank will grant you a HELOC.
- Maximum 65% HELOC: The HELOC alone cannot exceed 65% of the home value.
- Maximum 80% combined: Mortgage + HELOC together cannot exceed 80% of the home value.
Our calculator automatically checks these rules. If your current situation doesn't allow the Smith Maneuver, we tell you clearly with an explanation.
How the calculator works
The model reproduces the actual mechanics of a Canadian readvanceable mortgage:
- Each month, the principal repaid automatically frees up the same amount on your HELOC limit (readvanceable mortgage mechanic).
- You re-borrow that amount immediately to invest. Your total debt (mortgage + HELOC) stays constant.
- The portfolio compounds at the annual return rate you specify.
- HELOC interest is calculated on the average annual balance × your marginal tax rate = annual tax refund.
- The calculator stops automatically if you hit the Canadian cap: HELOC alone at 65% of home value, or combined LTV at 80%.

Frequently asked questions about the Smith Maneuver
Is the Smith Maneuver legal in Canada?
Yes, completely legal. It relies on Canada Revenue Agency rules (Bulletin IT-533) which allow deduction of interest on money borrowed to earn investment income. Over 100,000 Canadians use this strategy.
What minimum income do I need to use the Smith Maneuver?
There is no strict minimum, but the strategy is most effective if your marginal tax rate exceeds 30%. That roughly corresponds to taxable income of $55,000+ in most provinces.
What are the risks of the Smith Maneuver?
Main risks: (1) temporary investment value drops, (2) HELOC rate hikes that reduce net returns, (3) discipline required to not spend tax refunds. It is a long-term strategy (15+ years).
Do I need a HELOC to do the Smith Maneuver?
Yes — that is the key tool. You need a readvanceable mortgage like National Bank All-in-One, Manulife One, Scotiabank STEP, or BMO ReadiLine.
What should I invest the HELOC money in?
To comply with CRA rules, the money must produce income (interest, dividends, distributions). Popular choices: Canadian dividend ETFs (XDV, VDY, ZDV), eligible dividend stocks, bond ETFs. Avoid pure capital gains ETFs.
How much time does it take to manage each year?
With a tool like RSSUS.com, around 30 minutes per month for re-investing and 2 hours at year-end for tax prep. Without a tool, expect 5 to 10 hours a year for ACB tracking and calculations.
Does the Smith Maneuver work with a traditional mortgage?
No. You need a readvanceable mortgage combining mortgage + line of credit. If you have a traditional mortgage, you can refinance into one of these products (fees may apply).
What is the difference between RSSUS.com and a simple Excel spreadsheet?
RSSUS.com automates: broker CSV import, real-time price updates, per-security ACB tracking, eligible vs. non-eligible dividend distinction, CRA-ready reports for your accountant. No spreadsheet does all this.
