Main duties

This group performs some or all of the following duties:
    Construction millwrights and industrial mechanics
    • Read blueprints, diagrams and schematic drawings to determine work procedures
    • Install, align, dismantle and move stationary industrial machinery and mechanical equipment, such as pumps, fans, tanks, conveyors, furnaces and generators according to layout plans using hand and power tools
    • Operate hoisting and lifting devices such as cranes, jacks and tractors to position machinery and parts during the installation, set-up and repair of machinery
    • Inspect and examine machinery and equipment to detect and investigate irregularities and malfunctions
    • Install, troubleshoot and maintain power transmission, vacuum, hydraulic and pneumatic systems, and programmable logic controls
    • Adjust machinery and repair or replace defective parts
    • Operate machine tools such as lathes and grinders to fabricate parts required during overhaul, maintenance or set-up of machinery
    • Clean, lubricate and perform other routine maintenance work on machinery
    • Construct foundations for machinery or direct other workers to construct foundations
    • Assemble machinery and equipment prior to installation using hand and power tools and welding equipment.
    Textile machinery mechanics and repairers
    • Apply mechanical repair principles and procedures to make sure that machinery runs properly
    • Detect defects and excessive wear in machinery and identify slight differences in dimensions and shapes of component parts
    • Repair and overhaul electrical and mechanical systems on textile machinery and replace and align moving parts as required
    • Set-up and adjust complex machinery for new patterns and products
    • Analyze information to perform maintenance such as cleaning and lubrication of textile machinery, troubleshooting, and to test running and proper operation of machines
    • Confer with management to recommend equipment changes and modifications and in evaluating new equipment.

Employment requirements

  • Completion of secondary school and training courses or a vocational program is usually required.
  • Completion of a three- to four-year apprenticeship program or a combination of over five years of work experience and industry courses in industrial machinery repair or millwrighting is usually required to be eligible for trade certification.
  • Textile machinery mechanics hired from other industries may require additional training in textile processes and experience as a textile manufacturing machinery operator.
  • Industrial mechanic (millwright) trade certification is available, but voluntary, in all provinces and territories.
  • Construction millwright trade certification is available, but voluntary, in Quebec and Ontario.
  • Industrial sewing machine mechanic trade certification is available, but voluntary, in Quebec.
  • Red Seal endorsement is also available to qualified industrial mechanics or millwrights upon successful completion of the interprovincial Red Seal examination.

Additional information

  • Construction millwrights are mostly engaged in the initial installation of industrial plant machinery and equipment; industrial mechanics are more concerned with the post-installation maintenance and repair of machinery and equipment.
  • Industrial mechanics and millwrights may be cross-trained in a second trade such as pipefitting, welding, machining or electrical maintenance.
  • Progression to supervisory positions is possible with experience.
  • The Red Seal endorsement allows for interprovincial mobility.
