How to Report
If you’re concerned about noise from a stationary vehicle:

Noise from Moving Vehicles
What It Includes
Moving motor vehicle noise may include:
- Revving engines
- Speeding
- Loud exhaust systems
- Loud music
- Tire squealing
- Persistent honking
Note: The City does not investigate individual moving vehicle noise complaints. Instead:
- Complaints are used to guide enforcement strategies.
- Only Toronto Police Service (TPS) can stop moving vehicles under the Highway Traffic Act.
How to Report
If you experience persistent and excessive noise from moving vehicles:
- Try to speak to the person responsible (if appropriate).
- File a complaint online at toronto.ca/311 or call 311.
- Include specific details: type of noise, time, location, and frequency.
This data helps identify trends for targeted enforcement efforts in collaboration with Toronto Police Services.
Noise from Car Alarms
What Constitutes a Violation
A car alarm going off occasionally is not enough to be considered an offense. The noise must be both:
- Unreasonable – Disturbs peace or comfort beyond typical household or street sounds.
- Persistent –
- Continuously heard for 10+ minutes, or
- Heard intermittently over an hour or more.
What to Do
- Keep a log: Record dates and times of repeated alarms to help establish a pattern.
- Speak with the vehicle owner, if possible.
- Mediation is available: Free, voluntary community mediation is offered by TNG Community Services.
Reporting a Complaint
If the issue continues:
- Submit a complaint at toronto.ca/311, or
- Call 311 for further assistance.
