Condo Declaration, Bylaws, and Rules: What's the Difference?
Three different documents govern your condo, and they don't carry the same legal weight or the same process for change.
Every Ontario condo corporation is governed by three distinct documents that owners often confuse for one another. The declaration is the foundational document registered on title. It defines the units, common elements, common expense percentages, and exclusive-use areas, and it's the hardest of the three to change: an amendment needs a high level of owner approval, and it does not take effect until it is registered (section 107).
Bylaws govern internal administration and governance, things like board size, meeting procedures, and financial matters. The board can propose a by-law, but under section 56 it takes effect only after owners of a majority of all units vote to confirm it and it is registered. Rules govern day-to-day conduct: pets, noise, parking, and rental-related conduct. The board can make or amend rules, which must stay reasonable and consistent with the declaration and the Act, and a new rule generally takes effect 30 days after owners get notice unless owners requisition a meeting about it within that time (section 58).
Official Ontario sources
- Ontario Condominium Act, 1998Section 56 governs by-laws and section 58 governs rules; section 107 sets the owner-consent thresholds for amending the declaration.

What to check first
- 1Request all three current documents together. They're often bundled in one certified package.
- 2Check the declaration for your unit's exact boundaries and common expense percentage.
- 3Check the bylaws for governance procedures like quorum and director terms.
- 4Check the rules for day-to-day conduct restrictions.
- 5Note the amendment date on each document.
- 6Ask whether any amendments have been proposed but not yet adopted.
- 7Keep certified copies with your other ownership and closing documents.
Common mistakes owners make
- Treating the rules and the bylaws as interchangeable when they carry different legal weight and different amendment processes.
- Relying on an old copy instead of confirming the current, amended version.
- Assuming a rule that seems unreasonable is automatically unenforceable without actually checking.
- Not checking the declaration first when a dispute is really about unit boundaries or expense shares.
- Missing a recent rule amendment you weren't separately notified about in plain language.
Documents to gather
- The registered declaration
- Current bylaws
- Current rules
- Any amendment notices
- The status certificate, which bundles all three
- The corporation's rule amendment history, if available
When to get a closer look
- You can't tell which document actually governs a specific dispute.
- A rule seems inconsistent with the declaration.
- You're trying to understand the amendment process for a change you want to propose.
- You're buying and want all three documents explained in plain language.

Frequently asked questions
Which document is hardest to change, the declaration, bylaws, or rules?
The declaration is the hardest to amend: it needs the highest level of owner approval, and an amendment takes effect only when it is registered. A by-law takes effect only after owners of a majority of all units vote to confirm it and it is registered. Rules can be made or amended by the board, and a rule generally takes effect 30 days after notice to owners unless owners requisition a meeting to vote on it.
Can the board make a new rule without an owner vote?
Generally yes, provided proper notice is given to owners and the rule is reasonable and consistent with the declaration and the Act. Owners can requisition a meeting within 30 days of the notice, and if they vote against the rule at that meeting it does not take effect. This is different from by-law or declaration amendments.
What's actually in the declaration?
The declaration defines the units and common elements, each unit's proportionate share of common expenses, and any exclusive-use common element assignments, such as parking or lockers.
Where would I find a rule about pets or parking?
These are almost always found in the rules rather than the declaration or bylaws, since they govern day-to-day conduct rather than structural or governance matters.
How do I get the current, official version of all three?
Requesting a status certificate is one of the most reliable ways to get certified current copies of the declaration, bylaws, and rules together.
