Can You Borrow More on Your Mortgage in Ontario?
Last updated: June 2026
Yes, sometimes. If you already own a home in Ontario and want to borrow more against it, the next step is usually a full mortgage review rather than a simple renewal.
Depending on your equity, income, credit, current mortgage, and goals, the right option may be a mortgage refinance, a same-lender increase, a home equity line of credit, or a second mortgage.
The goal is not simply borrowing more. The goal is choosing the structure that solves the problem cleanly without creating unnecessary long-term cost or payment pressure.
Quick Answer
If you want to increase the amount borrowed on your mortgage in Ontario, lenders will usually treat that as new borrowing rather than a simple renewal.
That review may lead to a refinance, a HELOC, a second mortgage, or another equity-based solution depending on your situation.
The most important question is not only whether you can borrow more, but whether the new structure still makes sense financially a year from now.

What does borrowing more on your mortgage actually mean?
Borrowing more usually means accessing some of your available home equity and converting it into usable funds.
Ontario homeowners commonly review this option for:
- renovations or repairs
- debt consolidation
- family buyouts
- tax arrears
- business cash-flow support
- emergency expenses
- preserving savings or investments
Even if your property has substantial equity, lenders still review income, debts, credit history, affordability, and the reason for the funds before approving additional borrowing.
Main ways to borrow more in Ontario
Mortgage refinance
A refinance replaces or restructures your existing mortgage with a larger amount. This may fit larger borrowing needs, debt consolidation, renovations, or major restructuring. Penalties, legal fees, appraisal costs, and qualification rules should be reviewed first.
Same-lender increase
Your current lender may allow additional funds or another mortgage segment. This can be useful if preserving your current lender relationship matters, but product restrictions and qualification requirements vary.
Home equity line of credit
A home equity line of credit can provide flexible access to funds as needed. It may fit staged spending, but it is commonly variable-rate and requires payment discipline.
Second mortgage
A second mortgage is a separate mortgage registered behind your existing first mortgage. This may help preserve a strong first mortgage, but higher rates and fees are common.
How much more might you be able to borrow?
Many standard refinance discussions in Canada begin around a broad maximum of 80% of the property’s appraised value, minus existing secured debt already registered against the property.
That is only a starting point, not an automatic approval.
Simple Example
- Estimated home value: $800,000
- 80% loan-to-value: $640,000
- Current mortgage balance: $450,000
- Potential room before costs: about $190,000
Approval still depends on income, debts, credit profile, property type, and the structure being requested.
What lenders usually review
- Property value: appraisal or automated valuation
- Current mortgage balance: including other secured debts
- Income: salaried, self-employed, pension, rental, or commissioned income
- Debt obligations: credit cards, loans, vehicle financing, support payments
- Credit history: missed payments, collections, proposals, or bankruptcies
- Purpose of funds: renovations, consolidation, repairs, or other goals
- Property type: owner-occupied, rental, cottage, rural, or mixed-use
When borrowing more may fit and when it may not
It may fit when:
- there is enough equity available
- the new payment still fits your budget
- the borrowing solves a specific problem or supports a clear goal
- the long-term cost still makes sense
It may not be the best move when:
- the higher payment creates additional strain
- the refinance penalty is very large
- the borrowing only delays a deeper debt issue
- a smaller or lower-cost solution may work better
Costs and risks to review carefully
- Prepayment penalties
- Appraisal costs
- Legal and registration fees
- Possible rate increases
- Longer amortization periods
- Turning unsecured debt into secured debt
Important comparison point
A lower payment does not automatically mean the overall decision is better. Penalties, total interest cost, future flexibility, and long-term affordability all matter.
What if your mortgage renewal is coming up?
Renewal is often the best time to review whether your current mortgage still fits your needs.
However, once you want additional funds, the request usually becomes more like a refinance than a simple renewal.
You may also want to compare:
What if your bank says no?
A decline from one lender does not always mean there are no remaining options.
Sometimes the issue is timing, documentation, debt ratios, credit history, property type, or lender policy rather than the entire file being impossible.
Depending on the situation, it may still be worth reviewing:
Documents that usually help speed up the review
- current mortgage statement
- renewal notice if available
- estimated property value
- property tax information
- income documents and pay stubs
- business bank statements if self-employed
- list of debts to consolidate
- estimated amount needed

Frequently Asked Questions
Can I increase my mortgage amount at renewal in Ontario?
Sometimes. Once additional funds are requested, lenders usually treat the file as new borrowing rather than a standard renewal.
Do I need to re-qualify to borrow more?
Usually yes. Lenders commonly review income, debts, credit, property value, and affordability.
Can I borrow more without breaking my mortgage?
Possibly. Depending on the lender and mortgage structure, options may include a HELOC, second mortgage, or same-lender increase.
What is better: refinance or second mortgage?
That depends on penalties, rates, the amount needed, and whether preserving the current first mortgage has value.
