What Is a Condo Reserve Fund in Ontario? What Boards Should Understand
(From a Condominium Management Expert)
Practical Guidance for Smarter Governance in London & Sarnia, Ontario
If you sit on a condo board or own a unit, you have seen a line on your budget for the reserve fund, but you may never have been told plainly what it is or why so much of your condo fee flows into it. That single account is one of the most important financial safeguards your corporation has, and misunderstanding it is exactly how buildings end up facing surprise special assessments.
This guide explains what a condo reserve fund is in Ontario, what the law requires, what the money can and cannot be spent on, and how much a healthy fund should actually hold. By the end you will be able to look at your own building's reserve and judge whether your current management company is planning ahead or simply keeping the account open.
What Is a Condo Reserve Fund, and Why Does It Exist?
A condo reserve fund is a dedicated savings account that every Ontario condominium corporation must maintain to pay for the major repair and replacement of the building's common elements and assets. It is funded through a portion of the monthly condo fees owners already pay, and it is held in a separate account from the money used for everyday operating costs.
Think of it as the building's long-term savings account. Roofs, elevators, parking structures, boilers, windows, and paving all wear out on predictable timelines. The reserve fund exists so the money is there when those components reach the end of their life, rather than forcing owners to hand over a large lump sum out of pocket at the worst possible moment.
Maintaining this fund is not a nice-to-have. Under the Condominium Act, 1998, every standard condominium corporation in Ontario is legally required to establish and fund a reserve, and to hold it in its own account. That applies to buildings in London, Sarnia, and every community in between, regardless of size.
What Can a Condo Reserve Fund Be Used For in Ontario?
In Ontario, a condo reserve fund can only be spent on the major repair and replacement of the corporation's common elements and assets, never on routine operating expenses. This is not legal advice, but generally speaking under Ontario law, using reserve money for day-to-day costs like landscaping, cleaning, utilities, or management fees is prohibited.
Ontario condos run on two separate pools of money. The operating fund covers the recurring, predictable costs of running the building each year. The reserve fund covers the large, infrequent capital projects that arrive once every several years or decades. Keeping them separate protects owners from having a bad repair year quietly drained out of savings meant for the roof.
Typical reserve fund projects include:
• Roof replacement and major waterproofing
• Elevator modernization
• Parking garage and structural repairs
• Window, door, and balcony replacement
• Boiler, chiller, and major HVAC replacement
• Repaving driveways and parking lots
Costs that do not belong in the reserve include snow removal, landscaping, insurance premiums, and staff or management wages. Those are operating expenses, budgeted and paid every year.
How Much Should a Condo Reserve Fund Have?
There is no single dollar figure that fits every building. The right amount is set by a reserve fund study, a professional projection of the building's future repair costs that must look ahead at least 30 years. The study tells the board how much to contribute each year so the fund can cover each project as it comes due.
The Condominium Act requires a corporation to complete its first reserve fund study within one year of registration and to update it at least every three years after that. The study must be prepared by a qualified professional such as an engineer, architect, or engineering technologist, and it comes in three classes: a comprehensive study, an update with a site inspection, and an update without one. For a brand-new corporation, contributions cannot be set below 10% of the common expense budget until that first study is done. For a deeper look at how these studies work, read our guide: Reserve Fund Studies in Ontario: A Board's Guide.
As a benchmark, the Condominium Authority of Ontario's 2024 reserve fund survey found that standard condo corporations contributed about 36% of their total budget to the reserve on average in 2023, and roughly two-thirds contributed more than 30%. Your building may need more or less depending on its age and amenities, which is why the study, not a rule of thumb, sets the target. We break the numbers down further in How Much Should We Contribute to the Reserve Fund.
How Do You Know If Your Reserve Fund Is Healthy?
A healthy reserve fund is one funded at the level the reserve fund study recommends, every single year, with contributions that rise on the study's schedule rather than being frozen to keep fees flat. If your fund sits consistently below the study's projection, that is a warning sign worth addressing.
Good condominium management makes the reserve visible. Your current management company should be integrating the study into the annual budget, reporting the reserve balance against the study's projection at your meetings, and flagging any shortfall early enough to fix it with a modest fee increase instead of an emergency levy. If you only hear about the reserve fund once a year at the AGM, that is a gap in the service you are receiving.
At Sapphire, we find that boards who treat the reserve fund study as a living plan rather than a compliance checkbox avoid the funding crises that catch other boards off guard. It is a core part of proper condo corp management, and it is one of the clearest ways to tell strong condominium management in London Ontario and Sarnia Ontario apart from the bare minimum. If your board wants an outside read on where your reserve and financials actually stand, Sapphire offers a free financial review, a no-cost second opinion on your statements.
The pressure is real. In the same provincial survey, nearly two-thirds of corporations were told to increase contributions by more than 3%, largely because construction costs have climbed. Boards that acted early are in far better shape than those that deferred.
What Happens If the Reserve Fund Runs Short?
If the reserve fund does not have enough to cover a major project, the board usually has to levy a special assessment, a one-time charge on top of regular fees that can run into thousands of dollars per unit. An underfunded reserve can also make units harder to sell, because buyers and their lenders review the fund's health before closing.
A chronically underfunded reserve is the most common reason owners get hit with a surprise bill, and it shows up on the status certificate a buyer receives, which can complicate sales and mortgage approvals. Proper reserve planning is the best protection against all of it. For more on what a shortfall can trigger, read our guide: What Is a Special Assessment?
Frequently Asked Questions
Q: What is a condo reserve fund and how much should it have in Ontario?
A: A condo reserve fund is a mandatory savings account every Ontario corporation keeps for major repairs and replacements of common elements, like roofs and elevators. There is no fixed amount. A reserve fund study sets the target, and provincial data shows standard corporations contribute roughly a third of their budget on average.
Q: How do Ontario condo boards know if their reserve fund is underfunded?
A: Compare the current reserve balance against the projection in your most recent reserve fund study. If the fund is tracking below the study's recommended balance, or your study recommended a contribution increase you have not implemented, the reserve is likely underfunded and heading toward a possible special assessment.
Q: Can a condo reserve fund be used for day-to-day expenses in Ontario?
A: No. This is not legal advice, but generally speaking under Ontario law, reserve funds can only be used for major repair and replacement of the common elements and assets. Everyday costs such as utilities, cleaning, and management fees must be paid from the operating fund, not the reserve.
