Tunnel Boring Machine (TBM) Operators

North End Connectors, an Aecon-led consortium comprised of Aecon, FCC Construcción, and Ghella, is delivering the Yonge North Subway Extension Advance Tunnel project for Infrastructure Ontario and Metrolinx. YNSE Labour Co, the labour arm, are looking for **two (2)** Tunnel Boring Machine (TBM) Operators to join our team immediately in support of the Yonge North Subway Extension Advance Tunnel project. In this role, the Tunnel Boring Machine (TBM) Operator will be required to work from (1) the project office, located at 5650 Yonge Street, 18th floor, Toronto ON M2M 4G3; (2) the site office, located at 17 Ruggles Avenue, Thornhill ON L3T 3S4; and (3) at various tunnel construction sites. The language of work for the position is English. The Tunnel Boring Machine (TBM) Operator role will be responsible for the safe and efficient operation of an Earth Pressure Balance Machine (EPBM), maintaining precise tunnel alignment while advancing excavation. The role involves assisting in the assembly and commissioning if the machine, and subsequently operating and controlling the TBM from the control room, continuously steering the machine, balancing face pressure, and adjusting operating parameters to suit ground conditions. The TBM Operator will work closely with the Tunnel Foremen, mechanics, electricians, and survey teams to initially assemble the machine, install the TBM shields and cutterheads, and subsequently support consistent tunneling progress while ensuring compliance with safety, quality, and environmental requirements. Specifically, the main responsibilities of the position include: * Assembling, installing, and commissioning the TBM shields and cutterhead, including testing to confirm the machine is fully operational and ready for the safe commencement of tunnel excavation * Operating and controlling the TBM to advance the tunnel, including steering to maintain alignment using guidance systems and real-time control room data, and managing thrust, cutterhead rotation, articulation, and advance rate * Controlling and adjusting EPB functions such as face pressure, screw conveyor operation, and soil conditioning systems to maintain ground stability and optimizing excavation performance under varying conditions * Monitoring machine parameters including torque, penetration rate, chamber pressure, and conveyor performance, making real-time adjustments to maintain efficient and continuous operation * Coordinating segment erection activities from the control room, ensuring proper ring build sequence, segment placement, and alignment to support ongoing tunnel advancement * Overseeing muck evacuation through the screw conveyor and conveyor systems, ensuring consistent removal of excavated material with minimal disruption to operations * Conducting pre-start and end-of-shift checks on mechanical, hydraulic, electrical, and safety systems, and performing basic servicing such as lubrication and system checks to maintain operational readiness * Identifying
