Conveyor Mechanic

Ferrovial Construction Canada Inc. and VINCI Construction Grands Projects are undertaking the design, build, and finance the Ontario Line Southern Civil, Stations, and Tunnel (South Civil) package.

As Ontario Transit Group, we are now mobilizing our design and construction crews, with major works. The South Civil contract is anticipated to be completed in 2030.

The project will strengthen Ontario’s economy by supporting an estimated 1,500 jobs at the peak of construction.

What is the project?

• A six-kilometer tunnel and associated tunnelling works from Exhibition to Don Yard portal (west of the Don River).
• Stations:
  • One above-ground station to be integrated with the existing GO Transit Exhibition Station.
  • Two underground stations to be integrated with the existing TTC Osgoode and Queen subway stations.
  • Four new underground stations (King/Bathurst, Queen/Spadina, Moss Park, Corktown).

The benefits to Ontario!

Faster, more frequent, and reliable access to rapid transit with more than 227,500 people will live within a 10-minute walk of an Ontario Line station.

• Improve the quality of life for commuters by reducing daily travel time.
• Reduce crowding on the existing Line 1 (Yonge-University) subway.
• Up to 57,000 more jobs accessible by transit (in 45 minutes or less) for Toronto residents.
• Economic and community growth along the future transit line and thousands of job opportunities annually during construction.
• Reduction in traffic congestion, greenhouse gases, and fuel consumption by providing an alternative transportation option.

Job Description

The Conveyor Belt Mechanic is responsible for the installation, inspection, maintenance, and repair of conveyor belt systems used to remove excavated material (muck) from the Tunnel Boring Machine (TBM) to the surface. Conveyor systems are critical to TBM performance, enabling continuous excavation and high daily advance rates. The mechanic ensures the conveyor operates safely, efficiently, and reliably across curved alignments, long distances, steep gradients, and high‑capacity muck transport conditions. 

This role supports 24/7 TBM operations and requires working underground in confined, noisy, and dynamic conditions.

Key Responsibilities

• Install and assemble conveyor structures, frames, rollers, belt storage units, stacking systems, and vertical/horizontal belt interfaces as tunnelling progresses.
• Align and tension conveyor belts to ensure smooth operation, especially through curves, steep gradients, and long tunnel runs. 
• Support expansion of the belt line as tunnelling advances, including adding belt storage segments and installing booster drives.
• Conduct regular inspections on belts, drives, rollers, take‑up units, pulleys, and belt tracking systems.
• Identify wear, damage, misalignment, or mechanical issues and perform corrective maintenance to prevent downtime.
• Perform belt splicing, patching, and replacement of worn components.
• Maintain booster drives, hydraulic tensioning systems, and drive motors for long‑distance conveying. 
• Monitor belt performance during mining operations and adjust belt speed, tension, and alignment as needed.
• Maintain the conveyor interface inside the TBM backup system, ensuring efficient loading of muck onto the belt.
• Work with TBM mechanics and operators to synchronize conveyor output with TBM production rate.
• Support muck extraction logistics, including preventing blockages, spills, or carryback.
• Follow all Ontario OHSA tunnelling safety requirements, including confined‑space procedures, ventilation rules, and underground hazard mitigation.
• Ensure safety guards, emergency stop systems, and communication devices are functional.
• Maintain clean work areas along the conveyor line, storage caverns, and TBM conveyor deck.
• Complete maintenance logs, inspection reports, repair records, and parts usage forms.
• Communicate mechanical issues promptly to shift supervisors, TBM crews, and maintenance leads.
• Coordinate with logistics and electrical teams during belt extensions or shutdowns.

Qualifications

• Completion of an apprenticeship program in Industrial Mechanic (Millwright) or equivalent experience (typically 3–4 years).
• Industrial Mechanic/Millwright trade certification (voluntary in Ontario but preferred).
• Belt technician or conveyor‑specific training (vulcanizing/splicing) is an asset.
• Valid Ontario safety training: Working at Heights, WHMIS, Confined Space, and Lockout/Tagout (as required).
• Strong understanding of conveyor system components: rollers, drives, pulleys, belt storage units, tensioners, and booster drives. 
• Experience with belt splicing, mechanical repairs, gearbox maintenance, and tensioning systems.
• Ability to read mechanical drawings, conveyor schematics.
• Proficiency with hand tools, power tools, welding equipment (asset), and alignment instruments.
• Ability to work in confined spaces, steep grades, long tunnels, and noisy environments.
• Comfortable performing physically demanding tasks and working extended shifts underground.
• Familiarity with muck removal logistics and TBM support systems.
• Strong problem‑solving skills, especially under time‑sensitive conditions during TBM production.
• Clear communication within multi‑disciplinary tunnelling teams.
• Ability to work independently and as part of a rotating shift crew.
