Government of New Brunswick


The Department of Health is regulating cooling towers under the Public Health Act. Building owners are responsible for obtaining a licence to operate cooling tower systems associated with their buildings, which include an evaporative condenser and fluid cooler.

Licensing is required by August 1st, 2022. There will be no fees for licensing in 2022 and licenses are valid until March 31st of each year.

The Department of Justice and Public Safety is responsible for ensuring compliance with the Act and Regulation.


A licence may be issued to a building owner who has completed an application for a licence and paid the required fee. Initial licence application fees have been waived until March 31st, 2023.


Following recent outbreaks of Legionnaires’ disease in the province, the Government of New Brunswick has committed to implementing a regulatory framework that will be introduced in 2 phases.

• Phase 1: includes mandatory licensing of Cooling Systems (cooling towers) by August 1st, 2022
• Phase 2: includes legislated requirements such as water management plans and Legionella testing. These details will be finalized after a stakeholder consultation process (to be held Fall 2022) and will be implemented by April 2023.

Violations of the Act or Regulation may lead to fines and/or licence suspension or revocation.
