Have you ever looked at a massive conveyor line, a robotic arm, or a complex bottling machine and wondered who installs it, keeps it aligned, and gets it back up when it fails? If you like solving mechanical problems with your hands and your head, the Industrial Mechanic (Millwright) trade in Ontario could be the right fit for you.

Job Description

Industrial Mechanics (Millwrights) are the skilled tradespeople who install, align, maintain, troubleshoot, and Repair heavy industrial machinery and mechanical systems. You’ll work in factories, food processing plants, Automotive facilities, power plants, mines, and warehouses—anywhere complex machinery needs to run safely and efficiently.

You’ll read technical drawings, plan installations, rig and move equipment, set precise alignments with laser tools, service bearings and gearboxes, and work on hydraulic and pneumatic systems. When a machine fails, you diagnose the root cause and bring it back online quickly, safely, and to specification.

Daily Work Activities

On a typical day, you might:

  • Attend a Safety meeting and review work permits and lockout/tagout plans.
  • Inspect a production line, identify wear on bearings, and schedule preventative Maintenance.
  • Use a hoist, chain fall, or Mobile Crane to move and position a new motor.
  • Perform a laser alignment between a motor and a pump, then test run and document results.
  • Troubleshoot a hydraulic leak, replace hoses and seals, and set proper pressures.
  • Fabricate a simple bracket or guard with basic machining or welding.
  • Collaborate with electricians, machinists, and process operators to complete a shutdown task.
  • Update maintenance logs and communicate with supervisors about parts and timelines.

Main Tasks (Installation and Repair of Heavy Machinery)

  • Install, level, and align industrial equipment (motors, pumps, conveyors, presses, mixers).
  • Perform precision alignment using dial indicators and laser alignment systems.
  • Set up and maintain hydraulic and pneumatic systems (valves, cylinders, hoses).
  • Diagnose and repair mechanical failures (bearings, couplings, gearboxes, belts, chains).
  • Conduct preventative maintenance and condition monitoring (Lubrication, vibration checks).
  • Read and interpret blueprints, schematics, and manuals.
  • Execute Rigging and hoisting to safely move large equipment.
  • Perform basic welding and machining to repair or fabricate parts.
  • Follow lockout/tagout and other safety procedures to control hazardous energy.
  • Complete work orders, documentation, and Compliance reports.
