  • The reserve fund may be used only for major repair and replacement of the common elements and assets of the corporation.
  • Owners fund it through their monthly common expense fees, and the board decides how much goes in.
  • The corporation must have reserve fund studies done by qualified professionals at set intervals and act on them within set deadlines.

If you are buying or already own a condo in Ontario, you will hear about the reserve fund in status certificates, budgets and board notices. It can feel abstract, but it affects your monthly fees and the chance of a surprise bill.

This article explains in plain words what the fund is for, who pays into it, and what the Condominium Act, 1998 requires the corporation to do to keep it healthy.

What the reserve fund is for

The reserve fund is money the condo corporation sets aside for big, expensive jobs down the road. Under the Condominium Act, 1998, it may be used only for major repair and replacement of the common elements and assets of the corporation.

That means it is not a general account for everyday costs. Routine items such as cleaning, building maintenance and management are paid from the common expense budget instead.

Who pays into it

Owners pay into the reserve fund through their monthly common expense fees. The board decides how much of the budget goes to the fund and may need to raise contributions to keep it adequate.

Your share of the common expenses is a percentage set in the declaration and may vary with unit size. For example, a unit with a 5% share of a $1,000 monthly budget pays $50 a month.

Special assessments and chargebacks are ownership costs separate from your regular monthly fees. A board can levy a special assessment through common expense fees without owner approval, for reasons that include unforeseen expenses, a major repair that exceeds its budget, and litigation costs. Your share of a special assessment uses the same percentage as your common expense share, and owners must pay it.

If a special assessment goes unpaid, the corporation has a lien against the unit that covers the unpaid amount, interest, and reasonable legal costs and expenses. There is an exception for buyers: in a court decision the Condominium Authority of Ontario describes, a buyer was exempt from their share of a special assessment because the status certificate had not clearly disclosed that assessments might be levied. Whether that could help in your situation depends on the facts, so it is worth confirming with a lawyer.

Reserve fund studies

The corporation relies on studies to know how much the fund needs. The rules differ depending on the stage of the building.

A study has two parts. The physical analysis lists components expected to need major repair or replacement within at least 30 years. The financial analysis includes a funding plan projected over at least 30 consecutive years. A component is listed only if its replacement cost is at least $500.

What the board must do after a study

StepDeadline
Review the study and propose a funding planWithin 120 days of receiving it
Send owners the Notice of Future Funding of Reserve FundWithin 15 days of proposing the plan
Implement the plan30 days from the date the plan was sent to owners and the auditor

The plan must make the fund adequate by the fiscal year after the study is completed. The notice includes a summary of the study, a summary of the plan, and a statement of any areas where the plan differs from the study. The study, plan and notice also go to the auditor.

Directors who depart from the study provider's professional advice may face liability, so boards are urged to be cautious about doing so.

What to do next

Frequently asked questions

Can the reserve fund be used for everyday expenses?

No. It may be used only for major repair and replacement of the common elements and assets of the corporation. Day-to-day costs like cleaning and maintenance come from the common expense budget.

How often must a condo get a reserve fund study?

A new corporation must complete a Class 1 study within the first year after registration. After that, updated studies are required at least every three years, alternating between Class 2 and Class 3.

What happens if the reserve fund is too low?

The board must propose a plan to make the fund adequate by the fiscal year after the study is completed. That may mean higher contributions through common expense fees, and a major repair over budget can lead to a special assessment.

Where can I see the state of the fund before I buy?

A status certificate may include a statement on the most recent reserve fund study and the state of the fund, and whatever it includes or leaves out binds the corporation. It must be provided within 10 days.
