HELOC & Home Equity Line of Credit in the GTA & Ontario

Your home has equity sitting there doing nothing. A HELOC, a home equity line of credit, turns that equity into a revolving credit line you can draw on, repay, and reuse. It is one of the most powerful and most misused financial tools in Canada. Here is how it actually works, and how to use it without getting burned.

How a HELOC actually works

A HELOC is a revolving line of credit secured against your home. You can borrow up to 65 percent of your home’s value in the revolving portion, and up to 80 percent combined with your mortgage. You draw what you need, when you need it, and pay interest only on what you use. Pay it down and the credit becomes available again. The rate is variable, so it moves with prime. Think of it as a giant, low-rate credit facility attached to your house. The minimum payment is usually interest only, which keeps payments low and, frankly, keeps undisciplined borrowers in debt forever. The tool is neutral. The outcome depends on the user.

Readvanceable mortgages: the product banks under-explain

A readvanceable mortgage pairs your mortgage with a HELOC in one product. Here is the part banks do not explain well: every time you make a principal payment on the mortgage portion, that amount automatically becomes available in the HELOC portion. Your credit limit grows as you pay down debt. Used with discipline, it is brilliant: your regular mortgage payments continuously rebuild your accessible credit. Investors use this to fund down payments on the next property. Business owners use it for opportunity capital. But most borrowers are never told how it works, so they just see a slightly more complex mortgage. Ask specifically for the readvanceable option and make the lender explain the mechanics before you sign.

Smart uses vs dumb uses of your equity

Smart uses: investing in assets that grow or produce income, funding a business expansion with real returns, strategic renovations that raise the property value, or a financial emergency buffer. Dumb uses: cars, vacations, and lifestyle spending that turn your home into an ATM. Here is the contrarian take most brokers will not give you: using equity to invest is not automatically smart either. If the investment does not reliably earn more than the HELOC costs, you are just leveraging your home for no reason. And using a HELOC to buy speculative stocks? That is gambling with your house as collateral. Every draw should pass one test: will this make me wealthier in five years? If not, do not draw.

HELOC vs refinancing: the honest comparison

Both access equity. A refinance gives you a lump sum with a fixed payment and the discipline of an amortization schedule. A HELOC gives you flexibility: draw, repay, redraw, with interest-only minimums. Refinance when you need a specific amount for a specific purpose and want forced repayment. Choose a HELOC when you need ongoing or uncertain access, like phased renovations or investment opportunities that come up over time. The honest trade-off: the HELOC’s flexibility is also its danger. No amortization schedule means no finish line unless you create one. I set up my HELOC clients with a self-imposed repayment plan from day one.

The rate trap most borrowers miss

Two things about HELOC rates that surprise people. First, the rate is variable and moves with prime, so your interest cost can rise. Borrowers who maxed their HELOC when prime was low got a painful education when rates climbed. Second, and this is the insider part: a HELOC is callable and reducible. The lender can reduce your limit or demand repayment if property values drop or your financial picture changes. It rarely happens, but it can, and it tends to happen exactly when you need the money most. Never treat your full HELOC limit as guaranteed money. Keep a buffer, and never fund something critical entirely with HELOC dollars.

Frequently Asked Questions

How much can I borrow with a HELOC?

The revolving portion goes up to 65 percent of your home’s value, and your total borrowing including your mortgage can reach 80 percent. On an $800,000 home with a $400,000 mortgage, that is up to $240,000 in available credit. Your income still needs to support the payments.

Is HELOC interest tax deductible?

Sometimes. In Canada, interest is deductible when the borrowed money is used to earn investment or business income. Interest on money used for personal spending is not deductible. The tracing matters, so talk to your accountant before drawing for investment purposes.

Can the bank reduce or freeze my HELOC?

Yes. HELOC agreements let the lender reduce your limit or freeze draws if property values fall significantly or your credit situation deteriorates. It is uncommon, but it is real. This is why I tell clients to keep a buffer and never rely on the full limit for critical plans.

Should I get a HELOC or a second mortgage?

A HELOC if you want revolving, reusable access and can handle the discipline of interest-only minimums. A second mortgage if you want a lump sum with a fixed repayment schedule and a clear end date. We will look at your purpose, your discipline, and your numbers, then pick.
