  • Typically, the board, sometimes with legal advice, drafts the specific language of the proposed change.

A condo board can’t just decide, on its own, to rewrite the rulebook. By-laws — the internal governance rules that cover things like how meetings are run, how the board is structured, and how the corporation manages its finances — belong to the owners collectively, not the board alone, and changing them follows a defined process.

Amending condo by-laws in Ontario means more than a board vote at a meeting. It generally requires owner approval, and, once approved, the amendment has to be properly documented and registered before it’s fully effective. Here’s how the process generally works.

By-laws vs. the Declaration vs. Rules: Know the Difference

Condo governance in Ontario operates on a few different levels of documents, and it matters which one you’re trying to change:

This article focuses on by-laws specifically — the middle tier.

Why By-laws Get Amended

Common reasons a board might propose a by-law amendment include:

The Amendment Process: Step by Step

  1. The board proposes the amendment. Typically, the board, sometimes with legal advice, drafts the specific language of the proposed change.
  2. Owners are given notice. Owners must be notified of the proposed amendment and given the opportunity to review it before voting, usually as part of the notice for a meeting.
  3. Owners vote at a properly called meeting. By-law amendments generally require approval by owners at a meeting — this isn’t something the board can finalize on its own authority. The specific approval threshold is set out in the Condominium Act and can be technical; confirm the current requirement with legal counsel rather than assuming a fixed percentage.
  4. The amendment is confirmed. Once owners approve it, the by-law amendment is formally adopted by the corporation.
  5. The amendment is registered. Condo by-law amendments generally need to be registered on title to be fully effective and binding going forward — a step usually handled with legal assistance.

Common Mistakes Boards Make When Amending By-laws

Because a defective amendment process can leave a corporation relying on a by-law that isn’t actually enforceable, boards are generally well served by involving a lawyer at the drafting stage rather than only after a dispute arises.

What Happens if Owners Reject the Amendment

If owners don’t approve a proposed by-law amendment, it simply doesn’t take effect — the existing by-law remains in place. A board can revise the proposal and bring it back for another vote, but it can’t impose the change unilaterally.

What Happens After a By-law Is Amended

Once registered, an amended by-law is binding on all current and future owners, including anyone who buys into the building afterward, whether or not they were around for the vote. This is one of the reasons buyers and their lawyers review a building’s by-laws — available through the status certificate and records requests — as part of standard due diligence.

Frequently asked questions

Can the board change a by-law without asking the owners?

No. By-law changes generally require formal owner approval at a meeting — the board can propose and draft the language, but it can’t adopt a by-law amendment unilaterally.

How is a by-law different from a "rule" the board posts, like a pet policy?

Rules generally cover day-to-day operational matters and can typically be established or changed by the board with a more limited process, subject to owners’ right to object under the Act. By-laws cover more foundational governance matters and require the fuller owner-approval process described above.

Do I get a say if I disagree with a proposed by-law amendment?

Yes — you’re entitled to notice of the proposed amendment and to vote on it at the meeting where it’s considered, either in person or by proxy.

Once a by-law is amended, can it be changed back later?

Yes, through the same process — a further amendment, proposed by the board and approved by owners, can revise or reverse an earlier by-law change.
