Home Equity and HELOCs in Canada: How They Work, and the Limits

This article is general information, not financial advice. Confirm the current terms and limits with a lender or a licensed advisor for your situation.

For most homeowners, the equity in their home, the value minus what they still owe, is their single largest asset. A home equity line of credit, or HELOC, is the most flexible way to borrow against it, and also the most misunderstood. Here is how it works, the limits that apply, how it stacks up against the alternatives, and the risks that are easy to underestimate.

The two numbers that define the limit

There are two loan-to-value ceilings, and they are commonly confused:

• A HELOC on its own is capped at 65% of your home's value.
• The total you can borrow against the home, a HELOC plus a mortgage combined, can reach 80% of its value.

Here is the part people miss: the amount between 65% and 80% cannot sit in the revolving HELOC. To borrow above 65%, that additional portion has to be an amortizing, non-readvanceable mortgage (a loan with a set repayment schedule that does not automatically free the credit back up as you pay it down), not the open credit line. So a HELOC alone tops out at 65%; getting to 80% means combining it with mortgage debt.

These are the rules that apply to Canada's federally regulated banks. Some provincially regulated lenders, such as certain credit unions, are not bound by the same federal guideline and may differ, so confirm with your specific lender.

How a HELOC actually works

• It is revolving credit. You can borrow, repay, and re-borrow up to your limit, like a credit card secured by your home.
• The rate is usually variable, based on the lender's prime rate (for example, prime plus a spread), so your cost moves when prime moves.
• You pay interest only on what you draw, and the minimum payment is often interest-only.
• It is often readvanceable, bundled with your mortgage so that your available credit grows as you pay the mortgage down.

HELOC vs. the alternatives

• Refinance: you replace your existing mortgage with a new, larger one (up to 80% of value) and take the difference as a lump sum. Watch for a prepayment penalty for breaking the current mortgage.
• Second mortgage or home equity loan: an additional loan on top of your first mortgage, usually a lump sum with fixed payments, ranking behind the first mortgage.
• Reverse mortgage: for homeowners 55 and older, borrow up to roughly 55% of the home's value with no regular payments (interest accrues against the eventual sale). A different tool for a different situation.

A HELOC's edge is flexibility; a refinance often has a lower rate but locks in a fixed amount and structure.

The risks worth taking seriously

A HELOC is useful, but it is debt secured by your home, so treat it accordingly:

• Your home is the security. If you cannot repay, the consequences can go as far as losing the home. This is not credit-card debt.
• The rate is variable. When prime rises, your payments rise, and a comfortable draw can become an uncomfortable one.
• Interest-only payments hide the principal. Paying only the minimum means the balance never shrinks. Regulators have noted that many Canadians carry HELOC balances for years without paying them down.
• The "home as an ATM" temptation. Easy access to a large credit line makes over-borrowing easy, which raises your leverage and your risk.

Using it wisely

A HELOC works best for a defined purpose with a repayment plan: financing a renovation that genuinely adds value, or consolidating higher-interest debt into a lower-rate one you actually pay down. It works worst as a way to fund ongoing lifestyle spending against your home. And if you are approaching a mortgage renewal, factor any HELOC into your overall borrowing picture before you commit.

Frequently asked questions

How much can I borrow with a HELOC? A HELOC on its own is limited to 65% of your home's value. Combined with a mortgage, total borrowing against the home can reach 80%, but the portion above 65% must be an amortizing mortgage, not the revolving line.

Is a HELOC's interest rate fixed? Usually not. It is typically variable, based on the lender's prime rate, so your payments change when prime changes.

What is the risk of only making the minimum payment? The minimum is often interest-only, so the balance does not go down. You can carry the debt for years and pay a great deal of interest without reducing what you owe.

HELOC or refinance? A HELOC offers flexible, reusable credit; a refinance often has a lower rate but a fixed amount and structure, and may carry a penalty to break your current mortgage. The right choice depends on why you are borrowing.
