Toronto's Noise Bylaw: What's Allowed, When, and How to Report It

Toronto has no single "quiet hours" rule: Chapter 591 sets a separate one for each kind of noise, and most change on Saturdays, Sundays and statutory holidays. Construction is tightest (nothing clearly audible 7 p.m. to 7 a.m. weekdays, nothing before 9 a.m. Saturdays, nothing at all Sundays and statutory holidays), while amplified sound and air conditioners have no curfew, only decibel limits that step down at 11 p.m. Set fines run $500 to $900; conviction can reach $100,000.

Which version is in force

The consolidation on the City's site is dated November 14, 2024: the date of By-law 1231-2024, the grassroots-organization fee waiver. By-law 878-2019 replaced the chapter outright on October 1, 2019; By-law 268-2024 rewrote it.

Be careful with 268-2024's dates. Its stamps run throughout the chapter, and only two carry an editor's note putting them in force September 1, 2024: both permit machinery, the Exemption Permit Screening Criteria definition and § 591-3.2. No Article 2 prohibition carries one, and § 591-4.5C, added by 268-2024 itself, treats June 1, 2024 as the changeover, finishing prosecutions begun "between October 1, 2019, and May 31, 2024" under the old text. By-law 288-2024, deemed in force that same June 1, set the exhaust limits. Everything here is quoted from that consolidation and checked against the City's noise page, modified July 2026.

The quiet hours, by type of noise

A Monday statutory holiday swaps the weekday rule for the weekend one, and where a sound falls under two sections § 591-2.10 says the most restrictive applies.

Construction: hours, not decibels

Section 591-2.3 bans construction sound "clearly audible" during the prohibited hours. There is no decibel test; audibility is the standard, so a 6:40 a.m. complaint needs no meter. The definition reaches from demolition and excavation to concrete work and equipment installation, "and includes any work in connection with these activities".

The way around them is a noise exemption permit, filed at least 28 calendar days ahead and screened into Level 1, 2 or 3; processing runs three to four weeks. The hours granted are whatever the permit says, with no by-law maximum. A general permit caps sound at a ten-minute Leq of 85 dB(A) or 105 dB(C), at the lot line for amplified sound, 20 metres from the source otherwise (§ 591-3.2D(4)). Continuous concrete pours and large crane work run under § 591-3.2F, which applies only the conditions in D(1), (2) and (7), so that cap does not bind them.

Monitoring is a band ("$85.45 to $111.40 per staff per hour" plus tax), and an event "may require more than one officer". Do not quote these off the Code alone. Chapter 441, Appendix C, Schedule 12 is dated July 1, 2025, and its modern noise block (refs 504–511) is marked "Annual Adj: Yes", which under § 441-4A puts those fees on an annual escalator: $114.40 × 1.04 = $118.98. A "No" is not a freeze; it is the absence of that instruction, and Council still moves such a fee by amending the appendix.

Two noise lines carry "No", an orphaned older pair. Ref 60 is the officer's base monitoring rate (missing from the modern block, which carries only the overtime rate), and it shows $79.00 where the City charges $85.45, a gap of $85.45 − $79.00 = $6.45. Ref 59, the appeal fee, sits in that pair at $405.00, while the appendix's four other per-appeal fees ($348.70 twice, $402.37, $1,025.01) are all "Yes". So treat $405.00 as Appendix C's July 2025 figure, not a confirmed price: the permit page publishes no amount, only "An appeal fee must also be paid". Confirm it with the City Clerk before filing. § 591-3.2E gives 21 days from the notice, with notice of hearing to every resident within 100 metres "at the applicant's expense". The reliefs differ too: § 591-3.2G(2) makes the Chapter 441 fees inapplicable to the City "or any of its agencies, boards or commissions", while G.1 spares a not-for-profit or grassroots cultural organization only "the associated exemption permit application fee": monitoring and late fees still land.

Decibel limits and conditions

A decibel figure without its measurement condition means nothing. Each limit states where the reading is taken, over what period, against what baseline.

Amplified sound and instrument sound (§ 591-2.1) is taken at an outdoor point of reception in a living area, as an Leq over ten minutes: 55 dB(A) or 70 dB(C) from 7 a.m. to 11 p.m., 50 dB(A) or 65 dB(C) from 11 p.m. to 7 a.m., seven days a week. Indoors, where an outdoor reading is not reasonable, 50 or 65 by day, 42 or 57 at night. Where ambient noise already exceeds the limit, A(2) swaps the test: the source may not be "equal to or exceeding" the ambient.

Stationary sources (§ 591-2.8A and B) are generators and fans, measured as an Leq over one hour outdoors at a point of reception in a living area: 50 dB(A) from 7 a.m. to 11 p.m., 45 dB(A) from 11 p.m. to 7 a.m., or "the sound level limit prescribed in provincial noise pollution control guidelines, if applicable", which can be lower. Indoors, 45 and 40, same alternative. No ambient clause here. Subsection C lifts A and B (and only A and B) off a source complying with a provincial Environmental Compliance Approval or registered on the Environmental Activity and Sector Registry.

Residential air conditioners (§ 591-2.8D and E) get the same one-hour Leq numbers: 50 dB(A) by day, 45 dB(A) from 11 p.m. to 7 a.m. outdoors; 45 and 40 indoors. Here there is an ambient clause, a notch looser: under D(2), where ambient exceeds the D(1) limit, the unit may not run at a level exceeding the ambient, not "equal to or exceeding".

Stationary motor vehicles (§ 591-2.5C): 92 dB(A) at idle, 96 dB(A) above idle, at least 50 cm from the exhaust outlet.

Construction, power devices and animals carry no decibel limit.

What is exempt outright

Section 591-3.1 makes five categories lawful at any hour or level: public-safety bells and sirens; emergency measures for health, safety or welfare; emergency highway work; government work, defined to include construction and maintenance by the City, Ontario or Canada and their agents; and waste collection. Traffic, aircraft, watercraft and trains fall outside the by-law, and officers do not respond to demonstrations, noisy parties or disorderly behaviour: those go to Toronto Police at 416-808-2222, or 911.

How to report it

Two City steps come before 311: weigh whether the noise is reasonable for a dense city, then speak to whoever is making it and, failing that, to "your landlord, condominium corporation, company or other entity that has the authority to resolve your noise concerns". Its contact table routes a neighbour "continually making noise" there, or to a mediator, before bylaw enforcement; free mediation runs through a City partner. The row that does reach enforcement is the other one: "persistent and unreasonable noise", in the ten-minute sense.

If that fails, call 311 or 416-392-2489, or file online. What moves a file:

• As many specific details as possible: "its time and location, as well as the type of equipment being used (if possible)", the City's wording for power-device reports it will not investigate, but what any file needs, plus the address it comes from. An animal complaint needs the address where the animal lives; your name is not shared with the owner.
• Contact details, and an email address if possible: staff call for more before investigating.

What actually happens next

Manage your expectations, because the City does: officers "are not emergency responders… and do not have the authority to immediately stop a noise event", and may not investigate an isolated complaint.

The Noise Team's standard is a first contact (not a resolution) within 24 hours for Priority 1 (continual, neighbourhood-scale), 5 days for Priority 2 (recurring, such as early-morning construction), 7 days for Priority 3 (a party next door). The 311 Service Standard Dashboard for Q3–Q4 2025 says 10 days for Priority 3; take the ML&S figures, since the dashboard's three noise entries list only Priority 2 and 3 and end by pointing at that page, four months newer. Either way, the division adds there is "no set time frame within which service requests are resolved".

A barking dog runs on a different track. Animal noise goes to Toronto Animal Services, not the Noise Team. ML&S lists it among non-urgent animal requests at five business days, and the animal page warns it "may take up to five business days for the Officer to begin their investigation". Its route is four steps: educate the owner; an on-site visit, letter or Notice of Violation; a Noise Log proving the ten-minute test, "needed to satisfy the court by demonstrating that noise is… persistent and excessive"; then a charge before a Justice of the Peace, where "if you are unable to attend, the charges will be withdrawn". None of that chain is on the general noise page, which promises only a possible "witness statement and… evidence in court".

The penalties

Those are set fines, not the amount payable: a Chapter 591 ticket is a Part I offence notice under the Provincial Offences Act, so court costs and the provincial victim fine surcharge are added on top. Expect two numbers on the notice and pay the total it states. Section 591-4.1 stacks four higher ones: no more than $100,000 on conviction; a continuing offence charge up to $10,000 for each day or part of a day it goes on, the daily total "may exceed $100,000"; a special fine equal to the fair market value of the economic advantage gained; and personal liability up to $100,000 for each director or officer who concurred in a corporation's offence. An officer can also serve an Order to Comply and do the work at your expense.

What the complaint data shows

The City's 311 open data for 2025 carries 16,861 noise service requests across all ten request types.

Treat these as a floor: the file covers only requests whose location the City could validate, a subset of all 311 contacts. Two lines were never going to put an officer at anyone's door: moving-vehicle noise, one in six of the total, and "permitted or exempted". The City logs both, and power-device noise inside permitted hours, but investigates none of them.

Waste collection is the one place the City reports its own follow-up. Council approved a complaints process in November 2024 and staff promised quarterly updates; as of July 2026 the table shows one quarter, Q1 2025: 17 received, 17 actioned, 8 resolved.
