Buying a condo in Ontario means buying into a community governed by a declaration, bylaws, and rules — documents most buyers barely skim before signing. These documents control everything from what you can do with your unit to how much you'll pay in common expenses and what happens if the building needs major repairs. The declaration is effectively the condo's constitution. Once registered, it's extremely difficult to change. Understanding it before you buy is far easier than challenging it after.
What is a Declaration and Bylaws?
The condo declaration is a legal document registered on title that creates the condominium corporation and defines the rights, obligations, and restrictions for all unit owners. It works in conjunction with bylaws (which govern the corporation's internal management) and rules (which govern day-to-day use of the property). Together, these three documents — plus the Condominium Act, 1998 — form the legal framework that governs your ownership. The declaration takes priority over bylaws and rules in case of conflict.
Red flags to watch for
If the building is over 15 years old and the reserve fund study shows underfunding, you could face a special assessment of tens of thousands of dollars for major repairs.
Some declarations prohibit or severely restrict renting your unit. If you might need to rent it out in future, this is a critical limitation on your property rights.
Check how common expenses are allocated — if your unit's percentage seems disproportionate to its size, you'll be overpaying relative to other owners for shared costs.
Pet restrictions in a declaration are very hard to change and Ontario courts generally enforce them, unlike rules which may be challenged as unreasonable.
In new builds, the developer typically controls the condo board initially. If the declaration allows developer control beyond the statutory turnover requirements, owner interests may be subordinated.
If the board can levy special assessments without owner approval up to a high threshold, you could face unexpected charges with little recourse.
Your legal rights
The Condominium Act, 1998 (Ontario) provides extensive buyer protections. For new condos, you have a 10-day cooling-off period after signing the purchase agreement. The developer must provide a disclosure statement, and any material change to the disclosure gives you additional rescission rights. All condo corporations must maintain a reserve fund based on a professional reserve fund study updated every three years. The Act requires the developer to turn over control of the board to owners when a specified percentage of units are sold. Section 135 allows any owner to apply to court if the corporation's conduct is oppressive or unfairly prejudicial. The Condominium Authority Tribunal (CAT) handles disputes about records, pets, vehicles, and parking.
