Reserve Fund Studies in Ontario: What Every Board Must Know
(From a Condominium Management Expert)
Practical Guidance for Smarter Governance in London & Sarnia, Ontario
Many condo boards in Ontario know they are supposed to contribute to a reserve fund each year, but far fewer understand the reserve fund study that should be driving those contributions. A reserve fund study is not optional, not a suggestion, and not something to schedule when you get around to it. Under the Ontario Condominium Act, 1998, it is a legal requirement.
If your board has never commissioned one, received one years ago and filed it away, or is unsure what to do with the results, this guide will walk you through everything you need to know. From what the study covers to who can perform it and how to use the results to protect your owners from a surprise special assessment, this is the information every Ontario condo board member should have.
What Is a Reserve Fund Study?
A reserve fund study is a formal assessment of the major common elements of a condominium property. It looks at what the building's components are, how long they are expected to last, and how much it will cost to repair or replace them over time. The results are used to determine whether the corporation's reserve fund contributions are sufficient to cover future expenses without requiring a special assessment.
Think of it as a financial health check for your building's long-term maintenance. Without it, a board is essentially guessing about how much money it needs to set aside, and that guess often turns out to be dangerously low. The most common trigger for a special assessment in Ontario is an underfunded reserve, and an underfunded reserve almost always traces back to a study that was never done, done poorly, or done and then ignored.
The study typically covers three things: a physical inspection of major components such as roofs, parking structures, windows, elevators, mechanical systems, and exterior surfaces; an analysis of each component's estimated remaining useful life; and a financial projection showing whether the current contribution rate will be adequate over a multi-year horizon. Some studies also include sensitivity analysis, presenting different contribution scenarios and the cost consequences of each.
When Is a Reserve Fund Study Required in Ontario?
This is not legal advice, but generally speaking under Ontario law, the Condominium Act, 1998 requires every condominium corporation to conduct a reserve fund study within the first year after the corporation is registered, and to update it at least every three years thereafter. This applies to the vast majority of condo corporations across Ontario, including those in London, Sarnia, and the surrounding areas.
The three-year cycle is a minimum. Boards with aging buildings, recent major repairs, or significant changes in the composition of common elements should consider updating the study more frequently. A building that had a major roof replacement since the last study, for example, is operating on outdated numbers if the study has not been refreshed.
The study must also be revisited when a major repair or replacement materially changes the expected useful life of a key component, or when the board has reason to believe the current study no longer reflects the property's actual condition. Waiting until the mandatory three-year cycle has passed can leave a board making contribution decisions based on stale data.

Who Performs a Reserve Fund Study?
The Condominium Act specifies that the study must be performed by a 'qualified person.' In practice, this typically means a licensed engineer or architect with direct experience in building condition assessments, although the Act itself defines the term more broadly. The Condominium Authority of Ontario (CAO) and the CMRAO both provide resources for boards navigating this selection.
When selecting a provider, boards should do the following:
• Verify that the provider carries appropriate professional liability insurance.
• Ask for references from other condominium corporations of similar size and building type.
• Confirm that the person has hands-on experience with reserve fund studies specifically, not just general building inspection work.
• Request a sample report so you can assess the level of detail, the assumptions used, and whether the conclusions are clearly tied to the physical findings.
• Clarify whether the study will include a site visit or rely primarily on document review. A study without a physical inspection is unlikely to give you reliable numbers.
London Ontario boards working with Sapphire Condominium Management are guided through this selection process, since choosing the wrong provider can produce a study that is technically compliant but practically useless for long-term planning. A compliant study and a useful one are not always the same thing.
How to Use the Results
Receiving a reserve fund study is the starting point for a critical conversation about the financial future of the corporation, not the end of the process. Once the study is in hand, the board is obligated to update the corporation's reserve fund plan, a multi-year projection of how contributions will be collected and used.
If the study reveals the current fund is underfunded relative to projected needs, the board has several options: increase annual contributions, phase in a contribution increase over a defined period, or explore whether certain lower-priority repairs can be responsibly deferred. What boards should not do is receive a study showing a funding shortfall and continue collecting the same contribution amount without addressing it.
Failure to act on the results of a reserve fund study puts both the corporation and individual board members at risk. Owners who suffer financial harm as a result of an underfunded reserve have pursued legal action against boards that had the information available and chose not to respond to it. The study creates accountability. It documents that the board knew what the building needed and what the funding gap was.

Common Mistakes Boards Make with Reserve Fund Studies
Even boards that commission the study on schedule often make errors that reduce its value. Here are the most frequent ones:
• Treating the study as a box to check rather than a planning tool. A study that sits in a filing cabinet and never influences contribution decisions is not doing its job.
• Selecting the cheapest provider without evaluating qualifications. A low-quality study can give boards false confidence that their funding is adequate, which is arguably worse than having no study at all.
• Failing to share the results with owners. Ontario boards are generally required to provide owners with information about the status of the reserve fund. Transparency is both a legal expectation and a governance best practice.
• Not revisiting the study after a major capital expenditure. If the corporation completes a significant repair between study cycles, the current study may no longer accurately reflect the building's condition or remaining useful life for affected components.
• Assuming the study's contribution recommendation is a ceiling rather than a floor. The study tells you the minimum needed; boards managing older buildings or buildings with deferred maintenance may need to contribute above the study's projections.
At Sapphire, we find that boards in Sarnia and London who treat the reserve fund study as a living planning document, rather than a compliance task, make better financial decisions and avoid the funding crises that catch other boards off guard.

Frequently Asked Questions
Q: How often does an Ontario condo corporation need a reserve fund study?
A: Under the Condominium Act, 1998, a reserve fund study must be conducted within the first year of the corporation's registration and updated at least every three years. Boards should also consider an update sooner if significant repairs have occurred since the last study, or if there is reason to believe the current study no longer reflects actual building conditions.
Q: What happens if a condo board in Ontario does not do a reserve fund study?
A: This is not legal advice, but generally speaking under Ontario law, failing to conduct a reserve fund study is a breach of the Condominium Act, 1998. It can expose the corporation and individual directors to legal liability, particularly if owners suffer financial harm as a result of an underfunded reserve. The Condominium Authority of Ontario (CAO) has compliance and enforcement mechanisms available to unit owners and others.
Q: Who pays for the reserve fund study?
A: The cost of the reserve fund study is a common expense of the corporation, paid from the operating fund and shared by all owners through their condo fees. The cost varies depending on building size and complexity but is a standard and expected expense for any well-managed condominium corporation in Ontario.
