Ontario condo-fee arrears can become much more serious than an overdue monthly bill. Under section 85 of the Condominium Act, 1998, a condominium corporation has a lien against an owner's unit and common interest when the owner defaults in contributing to common expenses. If the statutory steps are taken to preserve and register that lien, it can acquire priority over many existing encumbrances. That is why a mortgage lender may treat condo arrears as a collateral problem, not merely a budgeting problem.
Mortgage financing can sometimes cure the arrears, but the solution depends on the legal stage. A late condo account with no registered certificate, a registered condominium lien, and a lien already moving toward enforcement are three different files. The borrower should obtain the exact balance and legal status before comparing refinance or second-mortgage offers.
The Ontario condo-lien clock matters
The Condominium Act provides that the lien arising from a default in common expenses expires three months after the default unless the condominium corporation registers a certificate of lien within that period. A registered certificate can cover qualifying unpaid amounts, later defaults, interest and reasonable legal costs and collection expenses. The corporation must give the owner at least 10 days' written notice before registration.
Those statutory rules are one reason generic advice such as ‘just pay it before renewal’ can be dangerous. Multiple monthly defaults, notices, registration timing and the exact amounts covered can create legal questions that a mortgage broker should not resolve by inference. The financing file should use the corporation's current statement and the borrower's lawyer's title advice.
Why a condo lien can concern the first mortgage lender
Section 86 of the Condominium Act generally gives the condominium lien priority over registered and unregistered encumbrances, subject to statutory exceptions including certain Crown and municipal-tax claims. The corporation is also required to notify registered encumbrancers when a certificate of lien is registered; late notice can affect the extent of priority. For the mortgage lender, the issue is therefore not only whether the borrower owes $8,000 or $20,000—it is whether another claim against the same unit can rank ahead of the mortgage security.
A mortgage commitment should never be read as proof that the condo problem has been solved. The lender may still impose a condition requiring the lien or arrears to be paid, and the lawyer must be able to obtain the documents and discharge needed for closing.
The three financing states are not interchangeable
Worked example: the condo lien can consume the last refinance room
Illustrative assumptions only: a condo is accepted at $700,000; the existing first-mortgage payout is $500,000; condo arrears are $12,000; condominium legal/collection costs bring the lien payout to $16,000; and new mortgage legal, appraisal and financing costs are estimated at $10,000.
If the accepted value falls to $650,000, an illustrative 80% amount falls to $520,000 and the same transaction no longer works without additional cash or a different lender/structure. The important number is not gross equity. It is net closing capacity after every priority claim and transaction cost is included.
Option 1: cure the condo account before a new mortgage is necessary
When the amount is manageable and the first mortgage is otherwise healthy, direct payment can be the cheapest solution. The objective is to stop legal cost and priority risk from growing. If the borrower cannot pay immediately, the condominium corporation's willingness to accept an arrangement is a matter for the corporation and its counsel; do not assume an informal payment plan prevents statutory lien steps.
Option 2: ask whether mortgage-relief capitalization is actually available
FCAC's mortgage-relief page lists condo fees among charges that a financial institution may permit to be capitalized into mortgage principal. That can be useful where the lender is willing to cure the arrears without replacing the mortgage. It is lender-specific, increases principal and should be compared with the total cost of a refinance or second mortgage.
Option 3: refinance when several problems need one closing
A full refinance may be efficient when the first mortgage is already near renewal, the borrower also needs to consolidate other high-cost debt, or the current payment structure is no longer sustainable. The lender must still accept the condominium property itself, current value, income, credit and debt-service profile. Paying a condo lien does not create an exception to ordinary underwriting.
Option 4: use a second mortgage to preserve a strong first mortgage
When the first mortgage is inexpensive and the condo problem is smaller than the total debt, second-position financing can sometimes isolate the expensive borrowing to the cure amount. Compare the total dollar cost over the expected holding period, including lender/brokerage/legal fees where applicable, and identify exactly how the second will be repaid. A short-term second with no exit can turn a condo problem into a larger maturity problem.
Condo arrears can reveal a broader affordability problem
Common expenses are part of the property's recurring carrying cost. If the homeowner can make the mortgage only by not paying condo fees, the mortgage is not truly affordable on a whole-property basis. The post-financing budget should include mortgage payment, property taxes, current condo fees, any special assessment obligations known to the borrower, insurance and unsecured debts.

Documents that matter before a lender can price the problem
Where condo-arrears financing goes wrong
Bottom line
Condo-fee arrears can often be solved with financing when equity and overall qualification support it, but the legal priority of a condominium lien makes early diagnosis important. Confirm whether a certificate is registered, obtain the real payout, model usable equity after every closing cost, compare capitalization/refinance/second-mortgage options, and fix the recurring cash-flow problem that caused the arrears. Where a lien or enforcement step exists, the mortgage plan should be coordinated with an Ontario lawyer.
Questions about this topic
Practical answers for Ontario borrowers reviewing this mortgage topic.
Can unpaid condo fees create a lien on my unit in Ontario?
Yes. Section 85 of Ontario's Condominium Act, 1998 gives a condominium corporation a lien when an owner defaults in contributing to common expenses. The Act also sets rules for registering a certificate of lien, notice and enforcement. Because legal status depends on timing and notices, an Ontario lawyer should confirm the live lien position for a specific unit.
Why do mortgage lenders care so much about condo-fee arrears?
A properly preserved condominium lien can have priority over many existing registered and unregistered encumbrances, subject to statutory exceptions. The corporation must also notify registered encumbrancers when registering the certificate. That can turn a condo-fee problem into a direct security and title issue for the mortgage lender.
Can I refinance to pay condo-fee arrears?
Potentially. The new financing must fit the lender's property value, combined debt, income, credit and policy while producing enough net proceeds to pay the condominium amount and any required legal/discharge costs. A registered lien usually needs coordinated lawyer-to-lawyer payout and discharge work.
Can a second mortgage cure condo arrears?
Sometimes, particularly when preserving a favourable first mortgage reduces total cost. The combined leverage and payments still have to be sensible, and the second lender will want the condo arrears/lien resolved as part of closing rather than left ahead of its security.
Can my existing bank capitalize condo fees?
FCAC lists condo fees among charges a financial institution may allow a borrower to capitalize as part of mortgage relief. Availability depends on the financial institution and circumstances; capitalization increases principal and should be compared with other cure options.
