HELOC vs Mortgage: What's the Difference in Canada?

A mortgage and a home equity line of credit (HELOC) both use your home as security, but they work very differently.

A mortgage provides a set amount of money that is repaid over time, while a HELOC is revolving credit that allows you to borrow, repay and borrow again up to your available limit.

What Is a Mortgage?

A mortgage is a loan used to purchase or refinance real estate.

You borrow a specific amount and repay it over an agreed amortization period.

Mortgage payments normally include:

• Principal
• Interest

Depending on your agreement, your mortgage may have a fixed or variable interest rate.

As you make payments, your mortgage balance gradually decreases.

What Is a HELOC?

A home equity line of credit is a revolving line of credit secured by your home.

Instead of receiving one lump sum that you automatically repay over a fixed schedule, you receive access to a credit limit.

You can:

• Borrow when needed
• Repay the balance
• Borrow again
• Pay interest only on the amount you use

A HELOC can be standalone or combined with your mortgage.

HELOC vs. Mortgage: What's the Main Difference?

The biggest difference is how you access and repay the money.

A mortgage is structured debt.

You borrow a predetermined amount and make scheduled payments that gradually pay it down.

A HELOC is revolving debt.

You can continuously access available credit, similar to a credit card, as long as you stay within your approved limit.

How Do Mortgage Interest Rates Work?

Mortgages may have fixed or variable rates.

Fixed-rate mortgage

Your interest rate stays the same for the length of your mortgage term.

This gives you predictable payments.

Variable-rate mortgage

Your interest rate can change when your lender's variable or prime-based rate changes.

Depending on your mortgage agreement, your payment amount or the portion going toward principal may change.

Mortgage rates are usually lower than unsecured borrowing because your home secures the loan.

How Do HELOC Interest Rates Work?

HELOCs generally have variable interest rates.

The rate is commonly based on the lender's prime rate plus an additional percentage.

For example, a HELOC could be priced as:

Prime rate + 0.50%

If the lender's prime rate increases, the HELOC rate generally increases as well.

That means your borrowing cost can change even if your outstanding balance remains the same.

Is a HELOC More Expensive Than a Mortgage?

HELOC rates are often higher than mortgage rates.

A mortgage usually gives the lender a structured repayment schedule.

A HELOC offers more flexibility because you can borrow and repay repeatedly.

You are generally paying for that additional flexibility with a higher interest rate.

However, the exact difference depends on your lender, credit profile and current market rates.

How Much Can You Borrow With a HELOC in Canada?

A HELOC can generally allow borrowing up to 65% of your home's value.

However, any mortgage or other debt secured against your home also affects how much equity is available.

For example, suppose:

• Home value: $800,000
• Mortgage balance: $450,000

Your total secured borrowing cannot simply be calculated by taking 65% of the home value and ignoring the existing mortgage.

The lender considers your home value, current secured debt and applicable loan-to-value limits when determining your available HELOC.

Combined borrowing secured against a home may generally reach up to 80% of the home's value, subject to lender requirements and mortgage rules.

What Is Home Equity?

Home equity is the portion of your property you effectively own.

You can estimate it by subtracting debts secured against the property from the home's value.

For example:

• Home value: $700,000
• Mortgage balance: $400,000
• Home equity: approximately $300,000

Your equity can increase as you pay down your mortgage or if your home's value increases.

It can also decrease if property values fall or you borrow more against your home.

Do You Make Principal Payments on a HELOC?

Not necessarily.

Depending on the HELOC agreement, your minimum payment may only cover interest.

That means you could make the required payments without reducing the amount you originally borrowed.

For example, if you owe $30,000 and only make interest payments, you could still owe approximately $30,000 years later.

You can generally make additional payments toward the principal whenever you choose.

How Are Mortgage Payments Different?

Mortgage payments are normally structured to gradually reduce the loan balance.

Each payment typically goes toward both:

• Interest
• Principal

Over time, more of each payment generally goes toward principal as the balance declines, assuming the rate and payment structure allow it.

This provides a clear path toward paying off the mortgage.

Can You Have a HELOC and Mortgage at the Same Time?

Yes.

Many Canadian homeowners have both.

Some lenders offer a mortgage combined with a HELOC, sometimes called a readvanceable mortgage.

As you pay down the mortgage principal, additional HELOC credit may become available.

For example, paying down $10,000 of mortgage principal could potentially create additional available credit, subject to the lender's terms and borrowing limits.

What Can You Use a HELOC For?

HELOC funds can generally be used for many purposes, including:

• Home renovations
• Emergency expenses
• Debt consolidation
• Education
• Major purchases
• Investing
• Business expenses

Because your home secures the debt, consider the risk carefully before using a HELOC for discretionary purchases.

Can You Use a HELOC to Buy a Home?

A HELOC can sometimes be part of a home financing strategy, but it differs from a traditional mortgage.

Because HELOC borrowing is generally limited to a lower percentage of the home's value, you may need significantly more equity or a larger down payment.

For most homebuyers, a traditional mortgage provides a more structured way to finance the purchase.

Can You Use a HELOC to Pay Off Your Mortgage?

Technically, you may be able to use available HELOC funds toward mortgage payments or repayment.

However, this usually means replacing one form of debt with another.

You may move debt from a mortgage with scheduled principal repayment to a revolving HELOC with a variable rate.

That does not automatically reduce your overall debt.

Compare the interest rates, repayment structure and risks before doing this.

Is a HELOC Better for Renovations?

A HELOC can be useful for renovations because you do not necessarily need to borrow the entire project cost at once.

For example, if you have a $75,000 HELOC but only need $15,000 initially, you can borrow $15,000 and pay interest only on that amount.

You can access additional funds later as expenses arise.

This flexibility can be useful when renovation costs occur gradually.

Is a Mortgage Better for Large Borrowing?

A mortgage may be more appropriate when you need a large amount of money and want structured repayment.

Mortgage financing can offer:

• Lower interest rates
• Predictable payment schedules
• Long amortization periods
• Automatic principal repayment

That structure can make it easier to gradually eliminate a large debt.

HELOC vs. Mortgage for Debt Consolidation

Both may potentially be used to consolidate higher-interest debt, depending on your situation.

A HELOC offers flexibility, but you need discipline to repay the balance.

A mortgage refinance may allow debt to be rolled into structured mortgage payments.

However, using your home to consolidate unsecured debt increases the stakes.

Credit card debt that was previously unsecured becomes debt backed by your property.

You may also extend repayment over many years, potentially increasing the total interest paid.

What Are the Risks of a HELOC?

A HELOC can be useful, but there are important risks.

Variable interest rates

Your payments can become more expensive when rates rise.

Interest-only payments

Making only minimum payments can leave you in debt indefinitely.

Easy access to borrowing

Because repaid amounts become available again, it can be tempting to keep borrowing.

Your home is collateral

If you cannot repay the debt, your home is securing the obligation.

What Are the Risks of a Mortgage?

A mortgage also uses your home as collateral.

Potential risks include:

• Rising payments on variable-rate mortgages
• Renewal at a higher interest rate
• Prepayment penalties
• Long-term interest costs
• Foreclosure if you cannot meet your obligations

The difference is that mortgages generally provide a more structured repayment path.

HELOC vs. Mortgage: Which One Should You Use?

A mortgage is primarily designed for financing a home or borrowing a large amount with a structured repayment plan.

A HELOC may be better suited to homeowners who already have equity and want flexible access to funds.

A mortgage may make more sense when you want:

• Predictable repayment
• A lower interest rate
• Long-term financing
• Automatic principal reduction

A HELOC may make more sense when you want:

• Flexible access to money
• To borrow only when needed
• The ability to repay and borrow again
• Shorter-term financing backed by home equity
