Industrial Mechanical Services for Quebec and Ontario Plants

CNC Mechanical supports heavy-industry owners, plant managers and project teams with coordinated mechanical construction and maintenance services. From its Boucherville head office, the company works across Quebec and Ontario on scopes that demand disciplined planning, experienced field supervision and close coordination with plant operations.

The service portfolio is built around four established trades: boilermaking, millwrighting, structural steel and industrial piping. CNC can also mobilize those disciplines for planned shutdowns, industrial maintenance and selected commercial or institutional plumbing work. The goal is straightforward: give the owner a capable team for the defined mechanical scope while keeping safety, quality, schedule and production constraints visible throughout the work.

Four core industrial trades

Choose the service family that best matches your project, or send CNC a combined scope for review.

  • Boilermaking services cover industrial tanks and pressure vessels, heat-exchanger maintenance and bundle extraction, furnaces and rotary kilns, dust-collection equipment, reactors, heavy equipment handling and controlled flange bolting.
  • Millwright services cover mechanical work involving overhead cranes, conveyors, bucket elevators, turbines, crushers, compressors, gears and laser shaft alignment.
  • Structural steel services cover erection, reinforcement and modifications in existing plants, along with miscellaneous metals such as walkways, stairs, guardrails and industrial mezzanines.
  • Industrial piping services cover service and process piping, instrumentation and hydraulic tubing, pipe supports, hydrostatic and pneumatic testing, material purchasing and coordinated subcontracted specialties.

Planned work, outages and maintenance

Some projects fit neatly within one trade. Others require a coordinated team and a carefully sequenced outage window. CNC documents the ability to plan and execute plant shutdowns requiring workforces ranging from 50 to 500 people. Experienced superintendents oversee field execution, and CNC develops lifting plans for heavy-equipment handling within its documented project scope.

For ongoing plant needs, industrial maintenance connects service calls, planned work and major repairs with the relevant trade team. The plumbing division, established in 2018, serves commercial and institutional plumbing projects; service availability is confirmed for each location and scope.

Experience grounded in industrial work

CNC's public project portfolio includes work for Valero Energy, Suncor, Domtar, Greenfield Ethanol, Ivaco Rolling Mills, Port-Cartier and the Jacques-Cartier Bridge. The documented scopes include annual shutdowns, multi-trade work, piping installation, reactor work, structural reinforcement, conveyors, a bucket elevator and heavy mechanical equipment.

Credentials and project-specific authorizations should be reviewed during prequalification. CNC will align the quoted scope with the applicable drawings, owner requirements, inspection points and site rules rather than making a generic compliance claim.

Discuss your industrial project

Share the site, equipment, desired dates, available drawings and production constraints. CNC can then direct the request to the right trade team and clarify where specialist subcontractors or third-party inspections must be coordinated.

Frequently asked questions

Frequently asked questions

What industrial mechanical services does CNC Mechanical provide?

CNC's documented services include boilermaking, millwrighting, structural steel, industrial piping, planned shutdowns, maintenance, heavy-equipment handling and commercial or institutional plumbing.

Does CNC Mechanical work in both Quebec and Ontario?

Yes. The existing company materials state that CNC serves heavy-industry customers in Quebec and Ontario from its Boucherville head office. Availability is confirmed for each project schedule and site.

Can one project combine several trades?

Yes. CNC's portfolio includes multi-trade work, and a single RFQ can identify the boilermaking, millwright, steel and piping portions that need to be coordinated.

What should an industrial RFQ include?

Include the site, equipment, drawings, desired work window, operating constraints, known hazards, owner standards and the work expected from CNC. This helps the team define responsibilities and exclusions early.
