It is prohibited to make excessive noise that can bother neighbours.

This bylaw applies to TV sets, radios, musical instruments, or any device that produces sound, including certain vehicles and noise produced by construction and renovation work, especially between 10:00 p.m. and 7:00 a.m.

Also, the use of heat pumps, air conditioners, pumps and fans must not produce a noise level exceeding 53 dBa. In Greenfield Park, the maximum permitted is 50 dBa.

It is also prohibited to make noise in public places by any means whatsoever in order to attract attention or seek the public's patronage for commercial purposes.

For any additional information about excessive noise, please contact the police service.

Alarm system

On May 21, 2009, the conseil d'agglomération de Longueuil adopted a by-law establishing the fees applicable for certain public safety services, including false alarms. This decision was in part motivated by the need to make alarm system users and building owners aware of the operational impacts and costs of emergency services when they have to respond to false alarms.

The following paragraphs summarize the main provisions of the false alarm by-law. It does not replace the official text adopted by City Council. For legal purposes, please refer to the by-law's official text: CA-2009-108.

Main provisions applicable to the police and fire services:

  • Any applicable fee for an unnecessary triggering of an alarm is always billed to the building's owner.
  • The fees provided by the by-law are payable in full within 30 days after the invoice is sent.
  • Fees charged under by-law CA-2009-108 for false alarms are assimilated to the building's property taxes, which means that the non-payment of these fees can result in a procedure for the sale of the building for non-payment of taxes.
  • On December 31 of each year, the fee for false alarms will be indexed based on the average consumer price index.
