The Mechanical Inspections Unit promotes greater safety to life and property by maintaining uniformity in the construction, installation, inspection, repair and alteration of pressure retaining vessels, propane appliances, and fixed conveyances such as elevators.
To help ensure safe, professional installation and maintenance, Mechanical Inspections administers various Acts, Regulations and Codes, and issues licenses, certificates and permits, related to:

Boiler and Pressure Vessels Act & Regulations
Operation and Supervision of Plants
Operating engineers must have the proper qualifying time and pass an examination to operate heating and power plants in the Yukon. Please contact Building Safety for more information on qualifying time and examinations for various certificates.
In order to be approved for use in the Yukon, a boiler or pressure vessel must have a Canadian Registration Number (CRN). To obtain a CRN, the boiler or pressure vessel design must be submitted for approval to the Chief Mechanical Inspector. The Manufacturer is required to fill out a data report and provide it to Building Safety indicating the owner’s name and location of the installed pressure vessel. Manufacturers will be invoiced for the fee to register their design.
Registration and Inspection
Once the boiler or pressure vessel is installed, it is the responsibility of the owner or mechanical contractor to inform Building Safety of the new installation. A registration certificate will be issued once the boiler or pressure vessel passes inspection; please phone Building Safety to arrange for an inspection.
Performance Qualification Tests for Welders
The Mechanical Inspections Unit conducts Performance Qualification tests for pressure welders. The pressure welder must hold a valid journeyman welder certificate to qualify for the test and complete an application form before being tested.
In the event of any accident concerning a boiler, pressure vessel, power plant, or heating plant, the owner or person in charge must notify the Chief Mechanical Inspector and submit a report as soon as possible after the accident.
2) Gas Burning Devices

Homeowners of single family dwellings who wish to perform the work themselves may obtain a gas installation permit after successful completion of a knowledge-testing questionnaire. Those approved to do their own work must apply for the permit, pay applicable fees, complete the work themselves, and reside or plan to reside on the property for at least one year.
