Applications & Forms

Managing Noise on Site

Adopt a noise control plan before work begins. Typical measures include scheduling noisy tasks during permitted hours, using modern mufflers and silencers, placing equipment away from sensitive receptors and installing temporary acoustic barriers. Provide advance notice to nearby residents and businesses when extended or evening work is planned.

  • Plan: schedule noisy activities within municipal allowed hours where possible.
  • Equipment: use low-noise machinery and maintain mufflers.
  • Permits: apply for temporary variances early if work falls outside standard hours.
  • Records: keep logs of complaints, notifications and mitigation measures.
Notify nearby residents at least 72 hours before extended noisy operations when feasible.

Reporting Complaints and Inspections

Neighbours can file noise complaints with the citys by-law enforcement service. Inspectors assess compliance, issue orders and may require immediate corrective measures. Contractors should cooperate with inspectors and preserve evidence of compliance actions.

  • How to report: use the citys by-law complaint form or phone line listed in Help and Support.
  • Inspection: an officer may attend the site and record noise levels and conditions.
Failure to comply with an enforcement order may lead to prosecution or stop-work directives.
