Can You Borrow More on Your Mortgage in Ontario?
Last updated: May 1, 2026
Yes, sometimes. If you already own a home in Ontario and want to borrow more against it, the next step is usually not a simple renewal. It is usually a new mortgage review that looks at your equity, income, debts, credit, current mortgage terms, and why you need the extra funds.
The right option may be a mortgage refinance, a same-lender increase, a home equity line of credit, or a second mortgage. The best structure depends on how much you need, how fast you need it, what your current mortgage looks like, and whether borrowing more creates a payment you can realistically manage.
This page is for Ontario homeowners who want to borrow more against a property they already own. It is not about qualifying for a larger mortgage to buy a new home, and it is not about simply increasing your regular mortgage payment.
Quick Answer
If you want to increase the amount borrowed on your mortgage in Ontario, you will usually need a fuller review rather than a simple renewal. That review may lead to a refinance, a same-lender increase, a line of credit, or a second mortgage.
A simple renewal usually keeps the balance the same. Once you want extra funds, most lenders treat that as new money and want to review the full file.
The key question is not only “Can I borrow more?” It is “Which option lets me borrow more with the least unnecessary cost, risk, and long-term payment pressure?”

What does it mean to borrow more on your mortgage?
Borrowing more usually means using available home equity to add new funds to your mortgage structure. Homeowners may look at this for renovations, debt consolidation, family buyouts, tax arrears, business cash flow, urgent repairs, or other major expenses.
For example, if your home is worth more than your mortgage balance, there may be equity available. That does not mean all of that equity can automatically be borrowed. A lender still needs to review your income, debt levels, credit profile, property value, current mortgage terms, and the reason for the funds.
A simple definition
In plain English, borrowing more means turning some of your home equity into usable money. The structure used to do that matters because the wrong structure can create avoidable penalties, higher total cost, or a payment that does not fit your budget.
What are the main ways to borrow more in Ontario?
There is no single best option for every homeowner. The right choice depends on your current mortgage, the amount you need, your timing, and whether flexibility or lower total cost matters more.
| Option | How it works | When it may fit | What to watch |
|---|---|---|---|
| Refinance | You replace or restructure your mortgage for a new amount. | Often worth reviewing for larger borrowing needs, debt consolidation, renovations, or major changes to the mortgage structure. | May involve penalties, legal fees, appraisal costs, and full qualification. |
| Same-lender increase | Some lenders may allow an increase, add-on, or additional mortgage segment. | May fit if you want to keep your current lender and the product allows it. | Availability depends on lender policy, mortgage type, equity, and full qualification. |
| Home equity line of credit | A secured line of credit gives access to funds as needed instead of one lump sum. | May fit when you want flexibility or expect to use funds over time. | Rates are often variable and payment discipline matters. |
| Second mortgage | A separate mortgage is placed behind your existing first mortgage. | May fit if you want to preserve a strong first mortgage or cannot refinance cleanly. | Usually higher rates and fees than a first mortgage. |
If you want to compare these in more detail, it usually makes sense to review the cost of breaking your current mortgage before deciding. Sometimes the cleanest-looking option is not the cheapest overall. Sometimes the opposite is also true.
How much more might you be able to borrow?
A common broad starting point for many standard refinance scenarios in Canada is up to 80% of the home’s appraised value, minus the mortgage balance and other registered secured debts already against the property. That is a starting point, not an automatic approval limit.
For example, if a home is appraised at $800,000, then 80% of the value is $640,000. If the current mortgage balance is $450,000, the rough room before costs may be about $190,000.
Simple equity example
- Estimated home value: $800,000
- 80% of value: $640,000
- Current mortgage balance: $450,000
- Possible room before costs: about $190,000
That still does not mean a lender will approve the full amount. Income, debts, credit, property type, and the structure being requested still matter. A line of credit may also be limited differently than a full refinance.
What do lenders usually review when you ask to borrow more?
Equity matters, but it is not the whole file. When a lender is being asked to approve extra money, they usually want a fuller picture.
- Property value: An appraisal or automated valuation may be needed.
- Current mortgage balance: The lender needs to know what is already secured against the property.
- Income: Employment, self-employed, pension, rental, or other income may need to be documented.
- Debt payments: Credit cards, loans, lines of credit, support payments, and vehicle financing affect affordability.
- Credit history: Missed payments, collections, proposals, or bankruptcies can affect lender choice and cost.
- Purpose of funds: Lenders may want to know why you are borrowing more and how the money will be used.
- Property type: Owner-occupied homes, rentals, cottages, rural properties, and mixed-use properties may be reviewed differently.
- Overall risk: The lender looks at the full story, not just one number.
Why does the Ontario context matter?
In Ontario, many homeowners reach this question while also dealing with renewal timing, payment pressure, credit changes, self-employed income, or a property that no longer fits neatly into a standard bank box. That is why the structure matters so much.
A homeowner in Milton, Oakville, Guelph, Mississauga, Burlington, Caledon, or anywhere else in Ontario may ask the same plain-English question: “Can I borrow more?” The answer often depends less on the city and more on the property, the mortgage already in place, and whether the new request still fits lender guidelines and the homeowner’s budget.
Who may this fit, and when may it not be the best move?
This kind of mortgage change can make sense when there is a clear reason for the funds and the payment still works after the change.
It may fit if:
- You have enough equity to support the new request.
- Your income and debt levels can support the new payment.
- The funds solve a specific problem or support a clear goal.
- The cost of borrowing is reasonable compared with the benefit.
- You have compared a refinance against a line of credit or second mortgage instead of assuming one option is best.
It may not be the best fit if:
- Your equity is too low.
- Your budget is already stretched and the higher payment would add more pressure.
- You only need a small amount and the refinance costs are too high.
- You have a strong first mortgage that may be expensive to replace.
- The new borrowing would only delay a deeper debt problem without a real plan.
What are common reasons people borrow more?
Ontario homeowners often ask about borrowing more for one of these reasons:
Renovations or major repairs
If the work is planned and the new payment still fits your budget, home equity can sometimes be a practical source of funds.
Debt consolidation
Some homeowners use equity to combine higher-interest debts into one payment. This can improve monthly cash flow, but it needs careful review because unsecured debt may become secured against your home. Learn more about debt consolidation mortgages in Ontario.
Separation, divorce, or family buyout
Borrowing more may be part of a buyout, but these files can also involve legal, title, timing, and qualification issues.
Tax arrears or urgent obligations
Equity may sometimes help solve an urgent problem, but urgency alone does not make one structure the right one. The repayment plan still matters.
Preserving a good first mortgage
If your current first mortgage has a low rate or a large penalty, replacing it may not be ideal. In some cases, a second mortgage may be worth comparing.
What costs and risks should you review before deciding?
Borrowing more can be useful, but it is not free money. Before choosing a structure, it helps to look at total cost and not just the monthly payment.
- Prepayment penalty: If you refinance before maturity, your current lender may charge a penalty.
- Appraisal fee: A current property value may be required.
- Legal and registration costs: These may apply when changing or adding secured borrowing.
- Rate change: Replacing a lower-rate mortgage may raise your cost of borrowing.
- Longer amortization: Lower payments can mean more interest paid over time.
- Securing unsecured debt: If you roll other debts into the mortgage, your home becomes security for that debt.
- Short-term fixes becoming long-term debt: This is one of the biggest risks when the reason for borrowing is not clearly planned.
Important comparison point
A lower payment can help, but it does not automatically mean the move is better. The full review should include penalties, fees, rate change, total interest over time, and whether the new structure still makes sense a year from now, not just today.
What if your mortgage renewal is coming up?
Renewal can be a very good time to review whether your mortgage still fits. But if you want to borrow more, it is important to start early.
A simple renewal usually keeps the same balance. Once you want extra money, the request may be treated more like a refinance. That can change the documentation, costs, timing, and qualification requirements.
If you are still months away from maturity, it may also be worth reviewing whether early renewal or a refinance strategy makes more sense than waiting until the last minute.
What if your bank says no?
A bank decline does not always mean there are no options. It may simply mean the request does not fit that lender’s rules, product type, or timing.
In some cases, another lender, an alternative lender, a private mortgage, a second mortgage, or a shorter-term solution may still be worth reviewing. The right answer depends on why the file was declined.
If the issue is income, credit, debt ratios, or property type, it may help to review pages on income issues and credit issues before deciding what to do next.
What documents should you have ready?
You do not need every document in the world before asking questions, but having the basics ready makes the review faster and clearer.
- Current mortgage statement
- Mortgage renewal notice, if you have one
- Estimated property value
- Property tax amount
- Income documents and recent pay stubs
- Business bank statements if you are self-employed
- A list of debts to be paid out if debt consolidation is part of the goal
- The approximate amount you want to borrow
- A clear summary of why you need the funds
- A penalty quote if the mortgage is still mid-term
What should you do next if you want to borrow more?
- Confirm your current mortgage balance and maturity date.
- Estimate how much you want to borrow and why.
- Check whether you may face a penalty if the mortgage is still mid-term.
- Compare the likely fit of a refinance, line of credit, second mortgage, or same-lender increase.
- Review the new payment and full cost before choosing a structure.
The goal is not just to find extra funds. The goal is to choose the structure that solves the problem cleanly without creating a more expensive problem behind it.
Need help comparing the options?
If you own a home in Ontario and want to borrow more, I can review the mortgage you already have, the equity available, the reason for the funds, and which structure may make the most sense for your situation.
That may mean a refinance, a second mortgage, a line of credit, or it may mean waiting. The point of the review is clarity before you commit to one path.
Frequently asked questions
Can I increase my mortgage amount at renewal in Ontario?
Sometimes, but borrowing more at renewal is usually not the same as a simple renewal. If you want extra funds, the lender will often treat the request as new borrowing and do a fuller review.
Is borrowing more the same as refinancing?
Often, yes. If you are increasing the mortgage amount, changing the structure, or taking equity out, the request is commonly treated as a refinance. Some lenders may also allow a same-lender increase or separate segment.
Do I need to re-qualify if I want to borrow more?
Usually yes. Since the lender is being asked to approve extra money, they normally review income, debts, credit, property value, and overall affordability.
How much equity do I need to borrow more?
Many standard refinance discussions start with the idea of lending up to 80% of appraised value, minus existing secured debt. That is only a broad starting point. Enough equity does not guarantee approval.
Can I borrow more without breaking my current mortgage?
Possibly. Depending on the lender and the mortgage already in place, it may be possible to use a same-lender increase, a line of credit, or a second mortgage instead of replacing the full first mortgage.
What is better, a refinance or a second mortgage?
It depends on the cost of breaking your current mortgage, the amount you need, and whether preserving your first mortgage has value. A refinance may be cleaner. A second mortgage may be worth comparing when the first mortgage is worth keeping.
Can I borrow more if I am self-employed or have credit issues?
Possibly. Those factors can limit lender choice or increase cost, but they do not automatically remove all options. The strength of the overall file still matters.
What costs should I expect?
Possible costs can include a lender penalty, appraisal fee, legal costs, registration costs, and higher borrowing costs over time. The exact mix depends on the structure used.
