A private second mortgage is a new charge registered behind an existing first. The first stays in place. The homeowner borrows additional funds against remaining equity. That is the product this article is about: not a bank refinance that pays out the first, and not a home-equity line from the same institution that already holds it.
The Financial Services Regulatory Authority of Ontario (FSRA) treats alternative and private mortgages as a temporary option, often for one or two years, until you can qualify for a lower-cost product. Among private mortgage options for Ontario homeowners, a second can look smaller than a full private first because it is only the extra money. Combined with the first, the cost, the term, and the exit still sit against the same home.
None of this is a promise that a private lender will approve you. It is an explanation of how a private second is structured, what combined loan-to-value actually measures, and why the first mortgage’s terms belong in the conversation before anyone orders an appraisal.
What a private second mortgage actually is
On title, rank matters. The first mortgage is paid first if the property is sold under power of sale or another enforcement process. A second sits behind it. That ranking is why a second is a different product from a private first, and why the size of the second alone is not the number that decides the file.
A private first replaces, or stands in, first position. A private second mortgage may be used when an existing first remains in place and the homeowner needs additional financing against available equity. Debt consolidation, a tax balance, a renovation, or a short cash need without breaking a first that still has a usable rate can sit around that product. They do not change what it is: a short-term private charge behind someone else’s first. A bank or credit-union second, and a home-equity line of credit, can sit in second position as well. Those products still look at income, credit, and debt ratios in ways that many private lenders do not copy. A private second is usually considered when those institutional options are unavailable or do not reasonably fit the borrower’s circumstances.
Combined loan-to-value, not just the size of the second
Equity is the gap between appraised value and what is already registered against the home. Loan-to-value is the lending amount as a share of that value. On a second, combined loan-to-value is the figure that matters: first mortgage plus the proposed second, plus fees that will be added to the loan, divided by the current appraisal.
Private lenders may place greater emphasis on the property, available equity and loan-to-value than a conventional bank, while income, credit and other borrower circumstances may still be considered and requirements vary by private lender. FSRA notes that private lenders will often give you a mortgage based on the value of your property instead of your income. That is a description of emphasis, not a rule that income never appears on a private application.
Private lenders set their own limits. Depending on the lender and the transaction, the required documentation may include an appraisal, title information and details of existing charges against the property. A municipal assessment from a prior year is not an appraisal. Unpaid property tax, condo arrears, a collateral charge that also secures a line of credit, and fees deducted from the advance all change the ratio on funding day.
When a private second may be considered
A second is only useful if the first can stay. If the existing lender is demanding a full payout, a second does not, by itself, retire a first-ranking charge. In that case the conversation is often a private first, or another institutional first, not a second stacked behind a loan that has to leave title.
When the first can remain, a short private second may be considered after a bank or B-lender second is unavailable or does not reasonably fit. That can include income a federally regulated lender cannot verify to OSFI Guideline B-20, a recent credit event, a timeline that will not wait, or a property those lenders will not book. OSFI’s rule does not directly apply to provincially regulated Ontario credit unions; their qualification requirements depend on applicable provincial requirements and their own underwriting policies.
If you are comparing private mortgage options for Ontario homeowners, start with whether the first can stay, what combined loan-to-value would be after fees, and whether a B-lender second is still realistic. Jumping to a private second because it can be arranged quickly is how people add an expensive term they did not need.
First-mortgage terms, consent, and title
Existing first-mortgage terms may restrict additional financing or require lender consent, so the mortgage terms and title should be reviewed by the borrower’s lawyer before adding a second charge. Some firsts are standard charges. Others are collateral charges that also secure a line of credit or future advances. A collateral first can reduce the equity a second lender is willing to recognize, even when the drawn balance looks modest.
Consent, due-on-sale language, and restrictions on further encumbrance are contract terms. They are not a reason to treat a second as automatically unavailable, and they are not a reason to ignore the first lender. Ask the existing lender, in writing, whether a second charge is permitted. Give that answer, and the charge itself, to your own lawyer. Do not sign a private commitment until title and the first-mortgage terms have been reviewed. A second lender may require property taxes, condominium common expenses and first-mortgage payments to be current, or may require certain arrears to be paid from the advance. A second that funds into an already strained first adds another payment and another maturity date on the same property.
Interest-only payments, fees, and a short term
FSRA is direct: it can be easier to get an alternative or private mortgage, but you may face higher interest rates and fees along with additional conditions or restrictions. Ask in writing for the interest rate, whether the mortgage is open or closed, how interest is paid, lender and brokerage fees, appraisal, legal, and discharge or renewal costs. Ask whether fees are deducted from the advance, added to the principal, or due in cash at closing.
Many private mortgages are structured with interest-only payments, so depending on the terms, the principal balance may not decline during the mortgage term. A lower monthly carrying cost is not the same as a shrinking balance. Twelve or twenty-four months later, the second can still be the amount that funded, while the first has barely moved. If fees were added to the loan and the property has not risen in value, combined loan-to-value can be no better, or worse, than when you started.
A private term is often one or two years. FSRA expects a realistic exit strategy, not a plan to double your income in six months. Common exits from a private second include a later bank or credit-union application that can carry both payments or a new first large enough to retire both charges, a move to a B-lender, a sale, or reducing the private balance so a conventional product can take it out. Ask whether this second lender will offer a renewal if you still cannot qualify, what that would cost, and what happens if you cannot pay the balance on maturity.
Risks, suitability, and a labelled hypothetical
A private second stacks cost on top of the first payment. It is a second claim on the home. Missed payments can lead to enforcement, and FSRA warns consumers to watch whether power of sale can start quickly after a missed payment. Do not sign until your own lawyer has reviewed the commitment. Any illustration you are shown is hypothetical until the numbers are in a written commitment.
FSRA requires mortgage professionals to assess whether a recommended mortgage is suitable for the borrower and to consider why lower-cost financing options are not appropriate. If a realistic bank, credit-union, or B-lender path still exists once the paper is assembled, a private second is usually the wrong first call. Suitability is about this borrower, this property, these existing charges, and a credible path off the private loan before that term ends.
The example below is hypothetical. It is not an offer, a quote, or a statement of what any lender will approve. Imagine an Ontario home appraised at $900,000, with a first mortgage of $480,000 and no other charges. Available equity before costs is $420,000. A homeowner wants $70,000 to pay down cards and a tax balance. Combined debt after a $70,000 second would be $550,000, or about 61 percent loan-to-value before fees. If lender and brokerage fees of a few thousand dollars are added to the loan, the ratio rises. A private lender may still decline, cap the amount, or require a different structure. Sixty-one percent on paper is not a pass, and the first lender’s consent still has to be checked.
In that same file, a B-lender second or a refinance of the first might still be the better product if income and credit can support it. The private second is the conversation when those options are unavailable or do not reasonably fit.
Licensing and questions to ask before you sign
In Ontario, when a private or alternative mortgage is arranged through a mortgage agent, the agent must hold the appropriate Level 2 licence; mortgage brokers can also arrange private mortgages. Level 1 mortgage agents are restricted to the lender categories permitted under Ontario licensing rules. A Level 1 mortgage agent may deal with traditional lenders such as banks and credit unions. Under the Mortgage Brokerages, Lenders and Administrators Act, 2006, material risks must be disclosed in writing and in plain language before you sign. Confirm the person is licensed with FSRA. Give the commitment to your own lawyer.
If a private second is on the table, ask why this product rather than a traditional or B-lender second or a refinance of the first, whether the existing first permits a further charge, what combined loan-to-value will be after fees, whether principal declines, what happens if you are late, whether renewal is available, and what the written exit is if the first plan fails.
