Millwrights work in construction and in manufacturing. They install, maintain, and repair stationary construction and industrial machinery and other mechanical equipment. Millwrights must have a good general understanding of the construction and manufacturing process, as well as the ability to test and troubleshoot completed work to ensure that it meets installation and operation standards.

In Ontario, Millwrights working in industry and manufacturing are called Industrial Mechanics or Industrial Millwrights, while those working in construction are called Construction Millwrights.

This fact sheet explains how to become certified as an Industrial Millwright in Ontario. In this fact sheet we will refer to the trade as Industrial Millwright.

Certification Requirements in Ontario

Certification to work in a trade in Ontario is called a Certificate of Qualification or the “C of Q”. Trade certification for Industrial Millwrights in Ontario is available through the Labour Market and Training Division Apprenticeship offices of the Ministry of Training, Colleges and Universities (MTCU). The legislation that regulates Industrial Millwrights is the Apprenticeship and Certification Act (1998).

Certification for Industrial Millwrights in Ontario is voluntary. This means that Industrial Millwrights can work without being certified. Although certification is voluntary (not required), it is recommended. Having the Certificate of Qualification will improve your chances of getting a job and of getting higher wages.

To become a certified Industrial Millwright in Ontario you must do one of the following:

  • complete a four-year apprenticeship in Ontario. Apprenticeship includes on-the-job training (about 90 per cent of the apprenticeship) and some in-school training (about 10 per cent of the apprenticeship). It is a training agreement between a person who wants to learn a skilled trade and an employer who needs a skilled worker. An apprentice earns at least minimum wage while working and learning the skills necessary to become a qualified tradesperson or journeyperson. Apprentices receive a Certificate of Apprenticeship when they complete their training, and are automatically eligible to challenge the Certificate of Qualification examination.


  • provide proof that you have completed an apprenticeship which combined work experience and theoretical training equivalent to an apprenticeship in Ontario.


  • provide documentation demonstrating 8,000 hours of full time work experience (excluding any technical training)

When you have done this, you must also:

  • complete and submit an application for the Certificate of Qualification (this applies to bullets 2 and 3 only);
  • pay the required fees; and
  • write and pass the Certificate of Qualification exam.

Competencies Required to Practise Your Trade in Ontario

Before you can receive government certification, you must complete training that covers the competencies listed in Apprenticeship Training Standards – Industrial Mechanic (Millwright). This document lists in detail all of the skills and work tasks that Industrial Millwrights must be able to demonstrate in order to be eligible to write the Certificate of Qualification exam. In Ontario, an employer who sponsors an apprenticeship signs off on each of the following competencies during an apprenticeship:

  • practise safety
  • communicate
  • read drawings and schematics
  • select and use hand and power tools
  • set up and use machine tools
  • use and maintain precision measuring equipment
  • select and use materials and fasteners
  • select and apply lubricants
  • install and maintain bearings, seals, and packing
  • rig and hoist
  • install and maintain materials handling systems
  • install and maintain power transmission systems
  • install and maintain compressors and pumps
  • install, commission, and maintain prime movers and machinery
  • weld, braze, and solder
  • install and maintain pipe systems and valves
  • install and maintain fans and blowers
  • install and maintain pneumatic systems
  • install and maintain hydraulic systems
  • perform preventative and predictive maintenance

As an internationally trained Industrial Millwright, you must be able to prove that you have these skills before you can write the Certificate of Qualification exam.

Language Requirements

When you apply for certification as an Industrial Millwright, you are not required to pass an English language test, but the job requires excellent language skills. As an Industrial Millwright, you must be able to communicate with other tradespeople, work well on a team, and have the ability to read and interpret engineering drawings and specifications, technical literature, and safety regulations. You must also be able to give and receive instructions clearly and effectively.

To become certified, you must write a technical multiple-choice exam, which requires a knowledge and understanding of the English terms used in this trade.

Application Process

There is no automatic certification for internationally trained tradespeople in any trade in Ontario, but there is an assessment process used to evaluate the training and experience of internationally trained tradespeople. The length of time that it will take you to become certified will depend on how closely your training and experience match the training standards for Millwrights in Ontario. If your application is accepted, you are immediately eligible to write the certification exam. If you require further work experience it can take up to four years if you have to complete a full apprenticeship.

Before You Emigrate To Canada

Apprenticeship Training Standards – Industrial Mechanic (Millwright) is a useful reference if you are unfamiliar with the terminology used and the skills required in Ontario. You can get a copy of this booklet from a Labour Market and Training Division Apprenticeship office in Ontario. (There is a list of these offices at the end of this fact sheet.)

You will need proof of your training and experience. Collect documentation that proves your skill level as an Industrial Millwright. Include letters from employers or unions, diplomas, and other documents that describe your training and the work tasks you have performed. These documents must also show where and for how long you have worked as an Industrial Millwright. It is important to include as much information as possible about your years of experience and your duties at work because the evaluation of your skills will be based on your on-the-job experience.

When You Arrive in Ontario

The Labour Market and Training Division Apprenticeship offices process all applications for trade certification in Ontario. When you arrive in Ontario, contact the office in your area and make an appointment to see a training consultant. If you haven’t already requested a copy of Apprenticeship Training Standards – Industrial Mechanic (Millwright), you can get one from the office.

Step 1. Meeting a Training Consultant

The training consultant will ask you for documentation that describes your past work experience and training. Take as many of these documents as possible to this first meeting:

  • your Social Insurance Number (SIN)
  • letters from current or past employers, dated and written on company letterhead, showing the company name and address, the exact dates of your employment, the number of hours that you worked, your title, and a complete description of your job duties
  • a letter from a union with the same information as above, if applicable
  • trade certificates, diplomas, or licences
  • official school transcripts from your training, if available. You should also provide a detailed list of the subjects covered in each course and the length of each course.

If these documents are in a language other than English or French, bring a translation that is signed by a registered translator, a notary public, or a lawyer.

The training consultant will use these documents to compare your work experience to the requirements for certification as an Industrial Millwright in Ontario.

Step 2. Assessment of Your Previous Training and Experience

The training consultant will assess your documents and compare your training and experience to that required in Ontario:

  • If your documented experience is equivalent to that required of an apprentice in Ontario, you will be eligible to write the Certificate of Qualification exam. You will then complete an application for the Certificate of Qualification.
  • If your documented experience is not equivalent to Ontario’s training requirements, you may have to get more training and work experience.

Training and work experience

If required, you can enter into an apprenticeship agreement to get on-the-job training. To get a position as an apprentice, you must apply directly to employers and find one to sponsor your apprenticeship. You will then register your apprenticeship agreement with a Labour Market and Training Division Apprenticeship office.

You can find employers by looking in the Yellow Pages (the telephone directory for businesses), or in local newspapers. Employers sometimes place job ads at government employment agencies. Employers want a well-written resume and for you to tell them how you will benefit their business and the trade.

Attestation of Competencies

In addition to providing documentation above, you will be asked to complete and sign an Attestation of Competencies. This document is an oath that you make, stating that you have all the competencies required for the trade. This Attestation of Competencies will be considered as proof that you are able to do the work of an Industrial Mechanic (Millwright). A false attestation is a serious criminal offence.

Step 3. Application for the Certificate of Qualification

When you have met the requirements for certification, you will complete an application for the Certificate of Qualification.

Step 4. Exam Preparation

The Certificate of Qualification exam is based on the skills that Industrial Millwrights need to succeed in the workplace. The content of the exam reflects both on-the-job and in-school training, as well as the National Occupational Analysis. This is why many workers who have not worked in Ontario find the exam difficult. The best way to prepare for the exam is to make sure that you can perform all the skills described in Apprenticeship Training Standards – Industrial Mechanic (Millwright). Study the competencies and be sure that you can explain the theory behind each task. Work experience is helpful before writing the exam.

Many community colleges offer pre-exam or exam preparation courses. These courses give applicants practice in writing the exams. They usually provide about sixty hours of training over several weekends and cost about $300.

Some community agencies may also offer special training courses for internationally trained Industrial Millwrights. Contact the Ontario Council of Agencies Serving Immigrants (OCASI) at the address shown at the end of this fact sheet. OCASI can provide information about settlement agencies in your community.

Step 5. Certificate of Qualification Exam

You may write the Certificate of Qualification exam for Industrial Millwrights at a Labour Market and Training Division Apprenticeship office once you have either completed an apprenticeship or shown (attested) that you have the competencies required for this trade. The exam is available year-round, usually by appointment. You can arrange a date to write the exam during your meeting with a training consultant, or you can call the Labour Market and Training Division Apprenticeship office to make an appointment to write the exam within ninety days of your application. You must show photo ID on the day of the exam.

Description of the exam

The Certificate of Qualification exam is a written exam with multiple-choice questions. These questions test your practical knowledge of workplace procedures and tasks. You are allowed three hours to complete the exam.


If you have difficulty with English you are allowed to bring a reader with you. Readers can be anyone whose English skills are strong; they may be relatives, friends, or interpreters from your community. Readers can translate the parts of the exam that you don’t understand, but they are not allowed to help you answer the questions. The exam is highly technical; make sure that you choose someone who knows English well, but does not have knowledge of Industrial Millwright work. Readers must sign a statement that they do not have any training or experience in the trade.

Dictionaries, pencils, erasers, and paper are available in the exam room. If you bring your own dictionary, you will be asked to submit it to the exam supervisor for inspection.

Pass mark

The pass mark for the exam is 70 per cent.

Rewriting failed exams

Your exam results will be mailed to you. The results sheet will detail the score as a percentage for each section of the exam, so if you fail, you will know which areas you still need to improve. You can rewrite the exam after 15 days.

If you fail the exam twice, you will be required to either take a refresher course to upgrade your training or get more work experience before you can try the exam again. There is a $100 fee every time you write the exam.

Step 6. Certificate of Qualification

If you pass the exam, your Certificate of Qualification will be mailed to you. Industrial Millwrights receive a lifetime certificate and renewal is not required. If you lose your certificate, you can get an official duplicate (copy) from the Labour Market and Training Division Apprenticeship office for a fee of $60.00

Fees and Costs

(in Canadian dollars)
Application for the Certificate of Qualification no fee
Registration of an apprenticeship, if required $40
Certificate of Qualification examination $100
Rewriting failed exams (re-examination) $100

Training and Upgrading

You may need to take upgrading courses to help you prepare for the exam. But training and upgrading doesn’t stop there. Industrial Millwrights work in industries that are constantly changing and where computer knowledge is increasingly required. Most Industrial Millwrights will require training and upgrading throughout their careers. Training and upgrading courses are offered by community colleges and trade schools, often as evening courses. The costs for these courses vary. Community colleges that offer Industrial Millwright training in Ontario include Mohawk, Humber, Conestoga, Niagara, Durham, Lambton, Sir Sandford Fleming, Cambrian, College Boreal, Fanshawe, George Brown, Georgian, La Cite, Sheridan, St. Clair, and St. Lawrence. Unions and other associations may also offer training courses.

Labour Market Information

The major employers in Ontario are primary steel producers, automotive assembly and automotive parts manufacturers, pulp and paper companies, electric power companies, mining companies, mechanical construction firms, and machinery and equipment manufacturers.

Industrial Millwrights who work in factories in Ontario work with the latest technologies and manufacturing systems, which incorporate computer-controlled equipment on production lines. Industrial Millwrights are expected to install, maintain, and repair “smart” machinery. To do so, Industrial Millwrights need a high level of skill and education, particularly the computer knowledge required to deal with the programmable logic controllers (PLCs) that are the “brains” of new equipment.
Most jobs (about 45 per cent) for Industrial Millwrights are found in southwestern Ontario. Industrial Millwrights usually work indoors at industrial plants or in commercial or institutional buildings. The average schedule is five days a week, for a total of 35 -40 hours. Shift work and overtime is common.
