What are Mississauga's construction noise hours?

The City of Mississauga currently lists commercial construction noise hours as 7 a.m. to 7 p.m., Monday to Saturday, excluding statutory holidays, unless an exemption has been granted. Confirm the activity and applicable rules for the site before planning work.
The by-law is updated from time to time and can include exemptions, so it is worth checking the City's current version before planning a job. Here is what the rules mean in practice.
What counts as construction noise
The by-law covers noise from construction activity, including the operation of equipment and machinery on a building or demolition project. Demolition hammers, concrete saws, excavators, compactors and trucks loading debris all fall within it. Quiet tasks such as hand clean-up or measuring are not usually the concern, but anything a neighbour can clearly hear is worth scheduling inside the permitted hours.
How the hours affect a demolition schedule
Most contractors plan the day around the by-law. A typical pattern looks like this:
- Set-up, protection and deliveries early in the permitted window
- Loud work such as breaking, cutting and machine demolition through the core of the day
- Loading and haul-away before the evening cut-off
- Quiet clean-up, bagging and inspection toward the end of the day
- No noisy work on Sundays or statutory holidays
Exemptions and special cases
The City can grant exemptions to the noise by-law in certain situations, for example when work must happen at night to avoid disrupting traffic or a business. These are applied for in advance and are not automatic. Emergency work needed to protect people or property is generally treated differently from planned construction.
Condominium buildings and commercial properties often set stricter rules than the by-law. A condo might limit renovation noise to weekday business hours, and a plaza landlord might require loud work to happen outside store hours within whatever the City allows. The stricter of the two rules applies in practice.
Being a good neighbour on top of the rules
Tell neighbours about the planned work, access arrangements and noisy activities. Keep loading routes and property boundaries clear. Permitted hours do not replace the need to manage disturbance and comply with other site requirements.
Noise in occupied homes
For an occupied home, discuss how the work area will be separated and how people will move through the property. Noise, dust and access should be planned together. The work plan determines whether rooms can remain occupied.

Frequently asked questions
Can demolition happen on Saturdays in Mississauga?
Generally yes, within the permitted daytime hours. Sundays and statutory holidays are generally off limits for construction noise.
Do condos have different noise rules?
Often. Many condominiums set stricter renovation hours than the City, and those rules apply on top of the by-law.
Can a contractor work at night?
Only with an exemption from the City or in genuine emergencies. Planned demolition is normally done in the daytime.
Where can I check the current by-law?
The City of Mississauga publishes its Noise Control By-law online, along with information on exemptions and complaints.
