Delivery: Full-time
Work Integrated Learning: Apprentice Placement
Length: 720 hours
Effective: Fall 2024
Location: Barrie


Graduates of the Machine Shop - General Machining Apprenticeship program have demonstrated achievement of vocational learning outcomes during in-school apprenticeship training that include the essential skills, knowledge, and attitudes for entry level positions in specific machining environments.

The 720 hour in-school program focuses primarily on theoretical knowledge and essential skills required to support the performance objectives of the Apprenticeship Training Standards. A General Machinist Apprenticeship includes three levels of in-school curriculum training which includes, but is not limited to, instruction in:

  • Applied trade safety practices
  • Applied trade calculations, charts, and tables
  • Engineering drawings/CAD (computer-aided design) data, layout processes
  • Metallurgy (science of metals)
  • Metrology (science of measuring and checking)
  • Benchworking techniques
  • Metal cutting saw technology
  • Drilling, turning, milling and grinding technologies
  • Computerized Numerically Controlled (CNC) technology

A General Machinist cuts, shapes and finishes metal to make precision machined parts and components used in all areas of manufacturing. General Machinist is a trade regulated by the Ontario College of Trades and Apprenticeship Act, 2009. Qualified individuals may obtain a Certificate of Qualification, which confirms its holder has the skills, knowledge and experience that meet industry standards of practice for the trade.

Career Opportunities

Machinists set up and operate a variety of machine tools to cut or grind metal, plastic or other materials to make or modify parts or products with precise dimensions. Machining and tooling inspectors inspect machined parts and tooling in order to maintain quality control standards. They are employed by machinery, equipment, motor vehicle, automotive parts, aircraft and other metal products manufacturing companies and by machine shops. 

Program Learning Outcomes

The graduate has reliably demonstrated the ability to:

  1. solve routine technical problems related to shop environments using a variety of systematic approaches; 
  2. interpret and produce basic graphics and other standard technical documents necessary for the routine installation, maintenance, repair, and manufacture of components;
  3. complete all work in compliance with health and safety legislation and prescribed organizational practices and procedures to ensure safety of self and others; 
  4. perform basic technical measurements using appropriate tools; 
  5. use shop tools and equipment for basic installation, manufacture, and repair of components to required specifications; 
  6. work responsibly and effectively within a shop environment in accordance with appropriate practices and procedures; 
  7. develop and implement a plan for CNC programming; 
  8. perform procedures for linear and circular machining in manufacturing; 
  9. perform various machining procedures, such as milling, turning and cutting according to plan. 

External Recognition

Upon successful completion of their Level 3 in school training, these apprentices must complete the remainder of the required skills outlined in the Training Standard Log Book to qualify for their Apprenticeship Certificate. Thereafter, they are eligible to write their Certificate of Qualifications exam for this Red Seal Trade.

Admission Requirements

  • Ontario Secondary School Diploma (OSSD) or equivalent, mature student status
  • Prospective students must register and be a member in good standing with the Ministry of Labour, Training, and Skills Development

Additional Information

An apprenticeship involves practical training provided on-the-job by a skilled worker, or trainer. The skills or competencies to be developed are set out by the trade’s Apprenticeship Training Standard and are recognized by the industry as being essential to the practice of the trade.

As these essential skills are developed, the apprentice’s sponsor or trainer signs the relevant sections of the training standard to indicate that the apprentice has met the individual training objectives by demonstrating the skills required of a skilled worker, or journeyperson, in the trade.

Graduation Requirements

Students must successfully complete all three levels to receive a certificate.

  • General Machinist Level 1- Basic (GMAB)
  • General Machinist Level 2- Intermediate (GMAI)
  • General Machinist Level 3- Advanced (GMAA)
