About Custom Contract Manufacturing Services (CCMS)
Custom Contract Manufacturing Services (CCMS) is a Bolton, Ontario manufacturing company specializing in large-part CNC machining, custom metal fabrication, steel fabrication, CWB-certified welding, assembly, equipment retrofitting, and material supply.
CCMS supports mining, heavy equipment, energy, industrial automation, and general manufacturing customers with individual manufacturing services or complete, coordinated production solutions.

Meet Founder Jason McMann

CCMS was founded by Jason McMann, a third-generation machinist with more than 20 years of manufacturing experience.
Jason began working in the industry at 14, deburring parts and sweeping shop floors. As he gained experience, he learned every stage of the manufacturing process—from manual machining and CNC programming to welding, fabrication, assembly, and full-scale production.
That hands-on experience shaped CCMS into a manufacturing partner capable of understanding the complete project, not just one production step. Jason remains closely involved in the work, helping customers solve difficult manufacturing challenges and ensuring projects receive careful attention from planning through completion.

What Makes CCMS Different?

CCMS combines large-part machining, metal fabrication, certified welding, assembly, retrofitting, and material supply through one Ontario manufacturing facility.
  • Large-Part Capabilities: CNC milling capacity up to 180 × 90 × 60 inches, live-tool turning for components up to 36 inches in diameter and 160 inches long, and handling capacity up to 40,000 pounds.
  • One Coordinated Supplier: Material supply, fabrication, welding, machining, finishing, assembly, and inspection can be managed through one manufacturing partner.
  • CWB-Certified Welding: Experienced fitters and welders provide MIG and TIG welding for demanding industrial projects.
  • Hands-On Experience: Every project benefits from practical machining, programming, fabrication, and production knowledge.
  • Flexible Manufacturing Support: CCMS handles individual operations, one-off components, replacement parts, equipment retrofits, and repeat production.

A Hands-On Approach to Manufacturing

CCMS was built around a straightforward goal: help manufacturers complete difficult projects with fewer suppliers, clear communication, and dependable workmanship.
Whether a customer needs one machining operation or a complete manufactured assembly, the CCMS team works to understand the application, identify potential production challenges, and deliver a solution that meets the project requirements.
