Full Breakdown
Ontario Municipal Code § 5-29.08 regulates noise from real property maintenance. Subsection (a) bars operating any tool, equipment or machine that produces loud noise disturbing a person of normal sensitivity except between 8:00 a.m. and 6:00 p.m. Subsection (b) narrows the window further for chainsaws and mulching machines used in trimming or pruning, allowing them only between 8:00 a.m. and 6:00 p.m. on a weekday and between 9:00 a.m. and 5:00 p.m. on Saturday or Sunday. Subsection (c) sets the identical schedule for electrical or gasoline powered blowers, such as commonly used by gardeners or other persons for cleaning lawns, yards, driveways, gutters and other property, meaning no leaf blower of either type may run before 8 a.m. or after 6 p.m. on a weekday, or before 9 a.m. or after 5 p.m. on a weekend.
Subsection (d) reaches beyond the operator: landowners, gardeners, property maintenance services, contractors, subcontractors and employers may not permit anyone working under their direction to violate the schedule. Limited exceptions in subsection (e) cover emergency property maintenance ordered by the building official, work on public facilities under specified conditions, and any maintenance activity that independently complies with the § 5-29.04 noise-level limits regardless of the hour. The rule targets timing, not decibels: a blower run at 7 a.m. violates § 5-29.08 even if it never crosses the numeric dBA ceiling that governs ordinary noise under § 5-29.04.
Violations & Fines
Running a blower, chainsaw or mulching machine outside the permitted hours is an infraction under § 5-29.17, fined per the schedule in OMC § 1-2.01, with each day of the maintenance work counted as a separate offense; Police or Code Enforcement Officers may instead issue an administrative citation under § 1-5.04, and the equipment's continued off-hours use can be abated as a public nuisance.
