A home equity loan can change the value you have developed in your Ontario home into cash for renovations or business. But the interest rate is only a section of the price. Lender fees and legal fees along with appraisals and a growing rate environment can involve thousands of dollars. This article highlights step by step process of calculating home equity loan costs and how to work out the actual cost of a home equity loan in Ontario before you sign one.
What Is a Home Equity Loan in Ontario?
A home equity loan is borrowing money in a secure way against the portion of your home you own legally. In Ontario it is generally registered on title as a second mortgage which implies that it comes behind your current first mortgage. You get a lump sum amount and repay it over a fixed term. A home equity line of credit (HELOC) functions differently. It is a revolving limit you can withdraw and repay continuously generally with interest only minimum payments. Lenders range from banks and credit unions to alternative and private lenders. Each price has its risk differently.
Step by Step Process to Calculate HELOC Costs
Step 1: Work Out How Much You Can Borrow
Start with your available equity. The basic formula is:
• Maximum new borrowing = (home value × lender's maximum loan-to-value) − current mortgage balance.
Suppose your home is appraised at $900,000 and you owe $450,000 on your first mortgage. At 80% loan-to-value, total borrowing could reach $720,000, leaving $270,000 available. At 75%, a common ceiling for private second mortgages on GTA homes, you could borrow $225,000. At 65%, the cap that applies to a HELOC, the figure falls to $135,000. Private lenders often go lower for condos or properties outside the Greater Toronto Area, so always confirm the limit that applies to your property.
Step 2: Calculate the Interest Cost
Interest is the largest single cost, and how you calculate it depends on the repayment type.
• Interest-only (HELOCs and many private seconds): annual interest = balance × annual rate. Divide by 12 for the monthly payment.
• Amortized loan: monthly payment = P × r ÷ (1 − (1 + r)^−n), where P is the loan amount, r is the monthly rate (annual rate ÷ 12) and n is the number of payments.
• Total interest = (monthly payment × number of payments) − principal.
Two cautions apply in Ontario. First, federally regulated lenders compound fixed-rate mortgages semi-annually, while many second mortgages compound monthly, so ask which applies. Second, HELOCs are almost always variable and follow the lender's prime rate, so your payment moves when the Bank of Canada does.
Step 3: Add Up the Upfront and Closing Costs
Closing costs reduce the money you actually receive, so include them. Published figures from Ontario lenders suggest these typical ranges, although they come from lender marketing material and your own quote will vary:
• Lender fee: about 1% to 3% of the loan, often deducted from the advance.
• Broker fee: about 1% to 3% if you use a mortgage broker, which should be disclosed in writing.
• Appraisal: roughly $350 to $700, although some lenders use no-cost desktop valuations.
• Legal fees: roughly $1,200 to $2,000 per lawyer, because the lender and borrower each need legal representation, and you often pay both.
• Title insurance: roughly $300 to $900.
• Discharge or payout fees: roughly $300 to $500 when the loan is repaid.
Ontario land transfer tax applies when title changes hands, so it generally does not apply when you simply register a mortgage on a home you already own. Confirm this with your lawyer.
Step 4: Look for Ongoing and Hidden Costs
Read the commitment letter for charges that do not appear in the headline rate:
• Renewal or extension fees if the term ends before you can repay.
• Prepayment or early-repayment penalties, often several months of interest on private loans.
• Administration, standby or annual HELOC fees.
• Penalties on your first mortgage if you break it to refinance instead of adding a second mortgage.
• Higher insurance, legal or default charges if you miss payments.
Step 5: Put It Together With a Worked Example
Here is an illustrative comparison for a $100,000 loan. All rates are assumptions for demonstration, not quotes. We assume $2,400 in third-party costs (appraisal $500, legal $1,500, title insurance $400) for each option.
HELOC (Prime + 0.50%), Interest-Only
· Rate Assumed: 5.20%
· Upfront Costs: $2,400
· Monthly Payment: $433
· First-Year Cost: $7,600
Alternative Lender (5-Year Amortized, 1% Lender Fee)
· Rate Assumed: 8.00%
· Upfront Costs: $3,400
· Monthly Payment: $2,028
· First-Year Cost: $10,788
Private Second (Interest-Only, 2% Lender + 1% Broker Fee)
· Rate Assumed: 9.49%
· Upfront Costs: $5,400
· Monthly Payment: $791
· First-Year Cost: $14,890
The first-year cost is interest plus all upfront costs. The amortized alternative-lender loan carries the highest monthly payment because it repays principal, but over five years its total interest would be about $21,658. The private second looks cheaper monthly, yet you still owe the full $100,000 at the end of the term and receive only $98,000 after the lender fee is deducted. To compare options fairly, divide first-year cost by the net amount you actually receive. On that basis the HELOC costs about 7.6% of the money received in year one, the alternative-lender loan about 10.9%, and the private second about 15.2%. The cheapest option on paper is not always the one you can qualify for, but a gap this wide is a strong reason to ask your bank or credit union first.
How Today's Rate Environment Affects Your Cost
The Bank of Canada raised its policy rate by 0.25 percentage points to 2.50% on October 28, 2026, and Canada's major banks moved their prime rate to 4.70% shortly afterwards, according to Ratehub. Because HELOCs and variable-rate loans track prime, a further increase would raise your payments. If you are borrowing on a variable rate, run your numbers at a rate one or two percentage points higher to see whether you could still manage the payment.
Ontario-Specific Checks Before You Sign
• Confirm that any mortgage brokerage or non-bank lender is licensed by the Financial Services Regulatory Authority of Ontario (FSRA).
• Ask for a written breakdown of the rate, fees and total cost of borrowing before you commit.
• Use your own lawyer where possible, rather than only the lender's, and read the mortgage terms carefully.
• Check how the debt affects your eligibility to refinance, since a second mortgage can complicate renewal of the first.
Ways to Lower the Cost
• Get quotes from at least three lenders, including a bank or credit union, before turning to private options.
• Borrow only what you need, since fees scale with the loan.
• Negotiate lender and broker fees and ask whether the appraisal and legal costs can be covered.
• Choose the shortest term and repayment style that fits your budget, and plan an exit such as refinancing or selling.
Frequently Asked Questions
How much does a home equity loan cost in Ontario?
It depends on the lender. Bank and credit union products are usually cheaper, with lower rates and few fees. Alternative and private lenders charge higher rates plus lender and broker fees, so total first-year costs can reach 10% or more of the loan.
Can I get a home equity loan with bad credit?
Often yes, through private or alternative lenders who focus on equity rather than credit score. Expect higher rates and fees, and some lenders still set a minimum score.
Is the interest on a home equity loan tax deductible?
Generally only if you use the money to earn business or investment income. Interest on money used for personal spending is not deductible, so speak to an accountant.
Do I need an appraisal?
Most lenders require one, though some low loan-to-value files use desktop valuations. Appraisal fees are typically a few hundred dollars.
What happens if I cannot repay at the end of the term?
You would need to renew, refinance or sell. Renewal can carry additional fees and a higher rate, and missing payments can lead to default charges and, ultimately, power of sale proceedings.
Is a second mortgage better than refinancing my first mortgage?
It can be if your first mortgage has a low rate or a large penalty to break. Compare the blended rate and all fees on both options before deciding.
Final Thoughts
The true cost of a home equity loan is interest plus fees plus the cost of any penalty or renewal, measured against the money you actually receive. Calculate each piece, compare at least three quotes, and stress-test the payment against higher rates. Speak with a licensed mortgage professional like Everlend or about your own situation.
