Noise Complaints in Ontario Condos: What Every Board Needs to Know

What Ontario Law Says About Noise in Condos

Under Section 117(2) of the Condominium Act, 1998, no person shall carry on, or permit to be carried on, any activity in a unit or the common elements that constitutes a nuisance, annoyance, or disruption to owners or occupants. Since January 1, 2022, noise is explicitly named in this section, giving boards a clear statutory basis to act.

Beyond the Act itself, most condo corporations have rules or by-laws that set quiet hours and define prohibited conduct. Those documents carry legal weight. Under Section 17(3) of the Condominium Act, the corporation is required to take all reasonable steps to ensure owners and occupants comply with the Act, the declaration, the by-laws, and the rules. That phrase, "all reasonable steps," means the board cannot simply choose to look the other way.

This is not legal advice, but generally speaking, under Ontario law, the duty to enforce is not discretionary. A board that consistently fails to respond to documented noise complaints can face liability, either through a court application or, increasingly, through the Condominium Authority Tribunal.

A Step-by-Step Process for Handling Noise Complaints

Boards that handle noise complaints well share one thing in common: a consistent, documented process. Responding differently to different complainants creates exactly the inconsistency that makes future enforcement harder and leaves the corporation vulnerable. A qualified property manager can implement this process on the board's behalf.

•       Receive the complaint in writing. Ask the complainant to document the date, time, nature, and duration of the noise. A written record protects everyone and makes escalation far easier if it comes to that.

•       Log it. Every complaint should be added to a central log maintained by the management company on behalf of the corporation.

•       Investigate. The board or manager should verify the complaint where possible. If the noise came from a specific unit, is there corroborating information from other residents?

•       Issue a written notice to the offending unit. The notice should reference the specific rule or section of the governing documents being violated. Keep the language factual and grounded in the documents rather than personal.

•       Follow up. If the noise continues after the first notice, escalate the language. A second notice can reference potential legal action and the CAT process.

•       Engage legal counsel if necessary. For persistent or severe violations, a letter from the corporation's legal counsel is often enough to resolve the matter without a tribunal application.

At Sapphire, we find that boards that treat the first complaint as an administrative process rather than a personal confrontation are far more effective at resolving these situations quickly and without further escalation.

The Condominium Authority Tribunal and Noise Disputes

Before January 2022, a board's only formal escalation option for persistent noise was a court application under Section 134 of the Condominium Act, an expensive and slow process. That changed when the Condominium Authority Tribunal expanded its jurisdiction.

The CAT now has authority to hear disputes involving noise, odour, light, vibration, smoke, and vapour under Section 117 of the Act. Both unit owners and condo corporations can file applications. The process is conducted online, is faster than court, and is significantly less expensive.

The CAT uses a staged approach: online negotiation first, then mediation, and finally adjudication if the parties cannot resolve the issue themselves. This makes it a practical tool for condo boards in London Ontario and Sarnia dealing with a unit owner who has repeatedly ignored written notices.

This is not legal advice, but generally speaking under Ontario law, Section 117(1) of the Act covers conditions that create a danger to health and safety, and those situations fall outside the CAT's jurisdiction. They are handled through the courts. The CAT focuses specifically on nuisance, annoyance, and disruption as defined in Section 117(2).

Common Mistakes Boards Make With Noise Complaints

Even experienced boards get this wrong. A few patterns come up repeatedly:

•       Treating it informally. A verbal acknowledgement that the board "will look into it" is not a response. It is an invitation for the complaint to resurface with more frustration attached.

•       Failing to document. If a matter ever reaches the CAT or a court, your paper trail is everything. Complaints with no written record are nearly impossible to adjudicate effectively.

•       Being inconsistent. If the board responds firmly to noise from one unit but quietly overlooks similar behaviour from a longtime owner, that inconsistency can be used against the corporation.

•       Confusing the corporation's role with individual mediation. The corporation enforces its governing documents. It is not the board's job to referee a personality dispute or collect evidence on behalf of one owner over another. The process is the process.

•       Waiting too long. Boards working with Sapphire in London Ontario and Sarnia sometimes raise noise complaints that have been simmering for months before management was ever notified. Delay weakens enforcement and damages the board's credibility with the broader community.

‍ ‍Frequently Asked Questions‍ ‍

Q: Does an Ontario condo board have to act on every noise complaint?‍ ‍

A: This is not legal advice, but generally speaking under Ontario law, the corporation is required under Section 17(3) of the Condominium Act to take all reasonable steps to ensure compliance with the governing documents. That does not mean every complaint results in formal enforcement action, but it does mean each complaint must be received, logged, and assessed. Ignoring documented complaints creates legal exposure for the corporation.

Q: Can a tenant file a noise complaint directly with the Condominium Authority Tribunal in Ontario?‍ ‍

A: No. Only condominium corporations and unit owners have standing to file applications with the CAT. A tenant who has a noise issue should raise it with the unit owner (their landlord), who may then choose to engage the corporation. The corporation's enforcement obligation extends to all occupants, but the formal CAT process is accessible only to corporations and owners.

Q: What are typical quiet hours in an Ontario condo, and does the province set them?‍ ‍

A: Quiet hours are set by each corporation's rules, not by provincial legislation. There is no standard provincial quiet-hour requirement for condos. Common rules specify windows like 11 PM to 7 AM, but boards can also set limits on renovation hours or common area noise. If your corporation's rules do not clearly define quiet hours, reviewing and updating them at your next AGM is a worthwhile conversation.
