Most Canadians think of their mortgage as a monthly expense; a financial weight they’re slowly chipping away at over 25 years.
But what if I told you that your mortgage (and more specifically, your home equity) could be turned into a wealth-building engine, one that accelerates your financial goals instead of delaying them? This is possible with the use of a Home Equity Line of Credit, or HELOC(short form).
When used properly, a HELOC against your home can be a flexible, tax-efficient, and strategic financial instrument available to homeowners.
What Is a HELOC?
A Home Equity Line of Credit is a revolving credit product secured against the equity in your home. Unlike a traditional loan, a HELOC allows you to borrow what you need, when you need it, and pay it back on your terms. It is just like an unsecured line of credit, however in this case because it is registered against your property, it carries lower interest rates than any unsecured credit product, starting around Prime + 0.50%(currently 5.2%). As the prime rate goes down, your HELOC rate will also decrease, and vice versa.
The real power with this product comes when it’s paired with the right strategy.
Strategy #1: The Smith Manoeuvre — Turn Bad Debt into Good Debt
If you own a home and still carry a mortgage, your payments are likely non-deductible, meaning you’re using after-tax dollars to pay it down, and getting zero tax benefit in return.
But with a re-advanceable mortgage (a mortgage + HELOC combo), every mortgage payment you make frees up available credit in your HELOC. That credit can then be reborrowed and invested into income generating assets, turning non-deductible mortgage debt into tax-deductible investment debt.
Here’s how our client Alex Is Doing It:
- Reborrowing $918/month from paid-down principal
- Contributing an extra $1,000/month in prepayments
- Starting with a $60,000 lump sum to “prime the pump”
- Targeting a conservative 8% return
- Staying 100% tax-compliant and deductible
- Capitalizing the HELOC interest only payments into the HELOC itself, so it does not affect his cash-flow.
Over 17 years, this strategy is projected to improve his net worth by $714,000 without requiring any extra income beyond what he’s already committing to his mortgage and investments.
Strategy #2: Use Your HELOC to Optimize Your Mortgage
Here’s something many homeowners don’t realize:
You can leverage your HELOC to pay down chunks of your mortgage principal each year, and then convert those portions into fixed-rate mortgage segments when interest rates drop, potentially lowering your blended rate over time.
This type of blended rate strategy gives you a level of rate control and flexibility that traditional mortgages can’t match. You’re no longer locked into one fixed product, and instead are managing your mortgage dynamically, based on market conditions. As you do this, you can also re-amortize your original mortgage to lower your payments. Keep in mind that this needs to be set up with the right lender that offers the options to turn HELOC balances into mortgage segments, as well as to re-amortize your existing mortgage payments.
Strategy #3: Consolidate High-Interest Debt
If you’re carrying credit card balances, car loans, or personal lines of credit with double-digit interest rates, your HELOC could be your lifeline.
Instead of paying:
- 19.99% on a credit card
- 9.9% on a personal loan
You could move that debt into your HELOC at much lower rates (often prime + 0.5% to 1.0%, depending on your lender).
This does two things:
- Lowers your monthly interest costs significantly
- Allows you to free up cash flow or pay down the debt faster
An optional step you could take then is to take that freed up cash flow and put it towards investments instead, or towards paying down your mortgage faster in the form of a lower amortization/extra prepayments. This way, cash flow wise everything stays the same on the front end, but in the back end you have increased your investments/debt paydown on your biggest loan.
Strategy #4: Invest in Income-Producing Assets and Make the Interest Tax-Deductible
Here’s where things get really interesting.
If you use your HELOC to invest in eligible, income-producing assets such as:
- Stocks or ETFs
- Paying for rental expenses or buying a rental property
- A business venture
… then the interest on those funds becomes tax-deductible in Canada (as long as the investment is structured properly).
This means you’re not only growing your wealth through investments, you’re also saving money at tax time. When done right, this can supercharge your long-term financial plan. Make sure to check with an accountant/CPA on this to get the right guidance, as well as what qualifies for the write off. This type of use on a HELOC requires the right tracking to ensure you have the right documentation ready in the event you are ever audited.
Key Benefits of a HELOC:
✅ Tax Efficiency – Turn non-deductible debt into deductible investment loans
✅ Flexibility – Borrow and repay on your schedule
✅ Debt Consolidation – Lower interest costs by moving high-interest debt into your HELOC
✅ Mortgage Optimization – Blend, restructure, and adjust as rates change
✅ Wealth Building – Invest borrowed funds to create long-term growth
✅ Cash Flow Management – Access equity in emergencies without breaking your mortgage
