On Oct. 1, the City of Toronto introduced amendments to the noise by-law that included changes to the regulations for construction noise. The amendments were enacted by city council in June as part of a broader noise by-law review to make the by-law easier to understand and enforce.
Continuous concrete pouring and large crane work are no longer exempt as-of-right from the noise by-law. Organizations that wish to undertake this work, or any other construction activity beyond the permitted hours of construction, will need to apply for a noise exemption permit.
A builder does not need a permit for each individual continuous pour or concrete finishing activity that extends beyond 7 p.m. Builders will need one exemption permit for the overall project duration which outlines approximate dates as to when these activities will be occurring.


Projects that will be completed by Dec. 31, 2019 and have existing building permits are not required to obtain a continuous pour and large crane work noise exemption permit.

Projects that will continue into 2020, and all new projects moving forward, will require a noise exemption permit for continuous concrete pouring and large crane work. These exemption permits should be applied for as soon as practicable. 


RESCON staff have been engaging with the City of Toronto since the original noise by-law review began in 2015. Our work has continued over the last several months as the amendments came into force. As part of this engagement, RESCON facilitated two construction site visits (above photo) recently for City of Toronto noise bylaw staff to get a better, field perspective of the concrete structure construction process for high-rise buildings.

As part of the new noise by-law amendments, once an exemption permit is granted, a notice of the exemption permit must be distributed to those within a 120-metre radius of the activity at least seven days prior to the event or activity.
Canada Post offers a service that may be helpful with the notice distribution. The service is called Precision Targeter and allows for the customization of mails-outs in a specific geographical area.
Additional information on how to use the Precision Targeter can be found here.

Municipal Licensing & Standards (ML&S) will review and approve or deny exemption permits for continuous concrete pouring and large crane work. Applicants must apply for a permit at least four weeks before the event or activity is to occur and understand further information may be requested.
ML&S can request a noise mitigation plan; reasons supporting an exemption permit; and/or a statement certified by a professional engineer or acoustical consultant. 
With the holiday season around the corner, we advise members who will have existing projects continue past Dec. 31, 2019, to apply for a noise exemption permit as soon as possible to prevent any interruptions to construction schedules in the New Year.

Applicants can now submit noise exemption permit applications electronically and in-person at the Licence & Permit Issuing Office. More information is on the City's website.
The City of Toronto has also developed a noise mitigation plan template which may be required as part of the noise exemption permit. Click here to see the Noise Mitigation Plan Template, which has been posted on the City's website.
