Hamilton noise bylaw: quiet hours, construction noise and how to complain
Hamilton, Ontario's Noise Control By-law 11-285 bans construction and loading noise clearly audible at a neighbour's property from 10 p.m. to 7 a.m., and a radio or speaker clearly audible there at any hour. It sets no decibel limit of its own for neighbourhood noise. Complaints go to Municipal Law Enforcement at 905-546-2782 on weekdays or 905-546-2489 after hours.

Quiet hours by type of noise
Hamilton's Noise Control By-law (By-law No. 11-285) has few clock times. Its general rule, § 3(1), bans "an unreasonable noise" and "a noise that is likely to disturb the inhabitants of the City" at any time of day. Section 3(2) then lists sources that are deemed to break that rule, half of them when the noise is "clearly audible at a point of reception", meaning "any point on a property where noise originating from other than that property is received". Only some of them have hours.
| Noise | Section | Not allowed |
|---|---|---|
| Construction or loading, clearly audible at a point of reception | § 3(2)(h), 5(d) | 10 p.m. to 7 a.m., every day. Exempt from 7 a.m. to 7 p.m.; from 7 p.m. to 10 p.m. the general rule applies |
| Radio, amplifier, speaker or similar device, clearly audible at a point of reception | § 3(2)(d) | At any time |
| Radio, amplifier or speaker in or on a vehicle, clearly audible at least 8 m away | § 3(2)(c) | At any time |
| Combustion or electric engine used for recreation (model airplanes, all-terrain vehicles), clearly audible at a point of reception | § 3(2)(f) | 10 p.m. to 7 a.m., and for more than 1 hour in total between 7 a.m. and 10 p.m. |
| Animal noise that is persistent and clearly audible at a point of reception (farms excepted) | § 3(2)(g) | At any time |
| Bell, horn, siren or other warning device, when unnecessary or for an unreasonable time | § 3(2)(a) | At any time |
The by-law has no separate Sunday or holiday hours, and no rule that names lawn mowers or leaf blowers; they fall under the general rule in § 3(1). The by-law defines "construction" as "activity necessary or incidental to erecting, demolishing, assembling, altering, installing, repairing or equipping a structure of any kind, a road or a utility including clearing, grading, excavating or filling any land", and "loading" as "loading, unloading, delivering, picking up, packing, unpacking or otherwise handling any containers, produce, materials or waste".
Since By-law 21-199 (October 2021), the by-law does not apply to noise from delivering goods to retail stores, restaurants (including cafes and bars), hotels and motels, or goods distribution facilities (§ 1a). It also does not apply to activities at Tim Horton's Field, permitted special events, permitted filming, vehicles operated by or for a government or utility (such as police, emergency services and Hamilton Street Railway buses), emergency work, traffic signals, normal farm practices, or activities that hold a provincial or federal environmental approval (§ 5). Anyone can apply for an exemption permit, intended for short events on private property, construction, and entertainment on commercial outdoor patios (§ 6).
Decibel limits
The by-law sets no decibel limit for ordinary neighbourhood noise such as music, voices or tools. For measured limits, § 4 bans noise that contravenes "an applicable Noise Pollution Control Publication of Ontario's Ministry of the Environment" or a permission such as an environmental compliance approval, so the figures for sources like industrial and commercial equipment come from those provincial documents. The only numbers written into the by-law itself are conditions on events and patios:
| Activity | Section | Limit | Hours |
|---|---|---|---|
| Special Event held under a City permit | § 5(b) | 90 dBA measured 10 m from the source; 60 dBA at a point of reception | Noise may not begin before 11 a.m. and must end before midnight |
| Entertainment on a commercial outdoor patio under an exemption permit | § 6(6A) | 60 dBA Leq measured at the property line | Thursdays, Fridays and Saturdays, 11 a.m. to 11 p.m. |
A special event permit can set its own conditions, which then prevail over these defaults (§ 5(b)(v)). The dBA scale discounts bass, which is why music can thump through a wall at a modest dBA figure; see dBA vs dBC. For an everyday complaint in Hamilton the test is not a number but whether the noise is clearly audible at your property, or unreasonable or likely to disturb.
How to complain
Noise complaints go to the City's Municipal Law Enforcement. The City's Register a By-law Complaint page lists three phone routes: Monday to Friday, 8:30 a.m. to 4:30 p.m., call 905-546-2782 and choose option 1 to speak with a By-law Clerk; outside business hours, call 905-546-CITY (2489) to log a complaint; and on Friday and Saturday from 5 p.m. to 1 a.m., call 905-546-2489 "to have a By-Law Officer dispatched immediately". You can also file online through my.hamilton.ca, but the City monitors online complaints only during weekday business hours and asks that urgent health and safety complaints be phoned in. Barking dog complaints go to the animal line, 905-574-3433, and a police, fire or medical emergency to 911.
A reading helps your record but is not the evidence, and for most noise Hamilton's test is whether it is "clearly audible" at your property, not a decibel figure. So a dated log of when you heard the noise, from where in your home or yard, and for how long counts for more than a number. The free online decibel meter runs in your browser and records nothing. It is an uncalibrated estimate of about ±10 dB, enough to tell 50 from 70 and to show that noise was there at a given time, but not to settle whether a measured limit was crossed; a provincial limit under § 4 needs a proper sound level meter. The noise complaints guide covers what to log.
Fines and penalties
The noise by-law is designated under the City's Administrative Penalty By-law (No. 17-225). By-law 18-043 set the penalty at $100 for each offence under § 3 (unreasonable or disturbing noise, a radio or speaker clearly audible at a point of reception, a loud car stereo, recreational engines, animals, and construction or loading at night) and $350 for noise that breaks a provincial noise publication or approval under § 4.
On conviction in court, § 7(21) makes an individual liable to "a fine of not more than $10,000.00 for a first offence and $25,000 for a second or subsequent offence", and § 7(22) a corporation to not more than $50,000 for a first offence and $100,000 for a second or subsequent one. An officer can also order the person responsible, or the owner or occupier of the property, to stop the noise (§ 7(9)), and a court can prohibit the offence from continuing (§ 7(23)).

The consolidation says it "is not the official or legal version of the by-law"; certified copies come from the City Clerk's office. Penalty amounts from By-law 18-043, which added Table 11 to Administrative Penalty By-law 17-225; none of the later amendments to 17-225 posted on hamilton.ca changes that table. Nuisance party penalties from By-law 22-235 and By-law 22-236 (Table 29 of By-law 17-225), as published on hamilton.ca.

The rules apply only within the City of Hamilton, Ontario, not Hamilton, New Zealand. Other Ontario cities have their own bylaws, such as the Toronto noise bylaw.
What are the noise bylaw hours in Hamilton, Ontario?
Hamilton has fewer clock times than most cities. Construction and loading noise clearly audible at a neighbour's property is banned from 10 p.m. to 7 a.m. every day, and recreational engines such as model planes and all-terrain vehicles from 10 p.m. to 7 a.m. A radio or speaker clearly audible at a neighbour's property, a loud car stereo, and persistent animal noise are banned at any hour, and any unreasonable or disturbing noise is banned at any time under section 3(1).
What time can construction start in Hamilton?
Construction and loading are exempt from the Noise Control By-law between 7 a.m. and 7 p.m. on any day, Sundays included (§ 5(d)). From 10 p.m. to 7 a.m., construction or loading noise clearly audible at a neighbouring property is banned (§ 3(2)(h)). Between 7 p.m. and 10 p.m. there is no fixed ban, but the work is no longer exempt, so it can be an offence if it is unreasonable or likely to disturb.
What is the Hamilton noise bylaw number?
The by-law is City of Hamilton By-law No. 11-285, the Noise Control By-law, last amended by By-law 21-199 in October 2021. To report noise, call Municipal Law Enforcement at 905-546-2782, option 1, Monday to Friday from 8:30 a.m. to 4:30 p.m., or 905-546-CITY (2489) outside those hours. The City's complaint page says that on Friday and Saturday from 5 p.m. to 1 a.m. the 2489 line can have an officer dispatched.
Is there a decibel limit in the City of Hamilton noise bylaw?
Not for ordinary neighbourhood noise. Most rules turn on whether a sound is clearly audible at your property, or unreasonable or likely to disturb. Section 4 adopts the Ontario environment ministry's noise publications and approvals as measured limits, which mainly concern industrial and commercial sources. The by-law's own figures apply only to permitted special events (60 dBA at a point of reception) and patio entertainment permits (60 dBA Leq at the property line).
What is the fine for a noise violation in Hamilton?
Under the City's administrative penalty system the set penalty is $100 for each offence under section 3, such as unreasonable noise, a speaker clearly audible next door, or night-time construction, and $350 for breaking a provincial noise limit under section 4. On conviction in court, an individual can be fined up to $10,000 for a first offence and $25,000 for a later one, and a corporation up to $50,000 and $100,000. A party with unreasonable noise, such as loud music or shouting, can also be a nuisance party under By-law 22-235, with set penalties of $500 for hosting it and $300 for attending (By-law 22-236).
