What Is a Millwright? Duties, Pay and How to Get Red Seal Certified

A millwright is a tradesperson who installs, maintains, troubleshoots, overhauls and repairs stationary industrial machinery and mechanical equipment: pumps, fans, conveyors, gearboxes, compressors, presses, generators, hydraulic and pneumatic systems, robotics and other automated equipment. The official Red Seal title for the trade is Industrial Mechanic (Millwright); provincial and territorial titles vary a little. It is a Red Seal trade, and in the National Occupational Classification it is NOC 72400, "Construction millwrights and industrial mechanics".

Job Bank puts the median wage for the trade at $37.00 an hour across Canada, and millwrights work across the many industries that use mechanical moving equipment: mines, petrochemical plants, power plants, factories, forestry operations and food processing plants. This guide explains what millwrights do day to day, the different job titles, where they work, what they earn in each province, the job outlook, and how you become a certified millwright with a Red Seal. "Red Seal certified" is the everyday phrase: in practice you hold a provincial or territorial certificate with a Red Seal endorsement on it.

Job Bank lists these as the main duties of construction millwrights and industrial mechanics. In plain terms, a millwright:

The 2026 Red Seal Occupational Standard, the newest national description of the trade, adds the full life of a machine: industrial mechanics (millwrights) assemble, install, fabricate, align, commission, maintain, repair, diagnose, inspect, dismantle, demolish, move and decommission equipment. They also use precision tools. Skilled Trades Ontario lists laser alignment equipment, dial indicators, micrometers and optical levels, and testing such as vibration analysis for preventive and predictive maintenance.

They may, depending on the job. The Red Seal standard lists welding, cutting, preparing bases for equipment, rigging and machining among the other tasks a millwright may do, and Job Bank lists welding equipment among the tools used to assemble machinery before installation.

Not as electricians. The Red Seal standard says industrial mechanics (millwrights) "are not electricians" and that provincial and territorial rules restrict or prohibit them from electrical work. In some places they may do limited work on electromechanical parts such as switches, relays and solenoids while installing or diagnosing hydraulic, pneumatic or automated equipment, so a working knowledge of voltage, current, resistance and a multimeter is part of the trade.

The names overlap in everyday use. Job Bank groups construction millwrights and industrial mechanics in one occupation (NOC 72400), while the certificate titles and routes vary by province and territory. The Red Seal trade title is Industrial Mechanic (Millwright); Red Seal also lists other titles used in some provinces and territories:

Job Bank explains the split inside the occupation. Construction millwrights are employed by millwrighting contractors. Industrial mechanics are employed in manufacturing plants, utilities and other industrial establishments. Both are counted as NOC 72400, along with apprentices and industrial textile machinery mechanics. Job Bank adds that construction millwright certification is available, but voluntary, in Quebec and Ontario, and lists related job titles such as maintenance millwright and plant equipment mechanic under the same occupation.

The Red Seal standard says industrial mechanics (millwrights) are employed in all sectors of industry that involve mechanical moving equipment, naming mining, petrochemical, power generation, manufacturing, forestry and processing facilities (food and service, among others). Job Bank lists the typical workplaces as industrial establishments, utilities, manufacturing plants and millwrighting contractors.

Job Bank says millwrights usually work 35 to 40 hours a week. The Red Seal standard notes the work "often" involves shift work, and that it can mean confined spaces, working underground in mines, at heights, with heavy equipment and around moving machinery, with a lot of standing, kneeling and lifting. Job Bank lists noise, hazardous machinery, dangerous chemicals, extreme temperatures and outdoor work in some jobs, along with standard and specialized safety equipment.

These are Job Bank's wages for NOC 72400, updated on 19 November 2025. Provincial figures come from Statistics Canada's Labour Force Survey for 2023-2024; the Northwest Territories and Yukon figures are 2024 estimates from a Statistics Canada model (Small Area Estimation), so compare them with the survey-based provincial figures with care. Job Bank shows no figure for Nunavut. Job Bank also says 94.6% of workers in the occupation get at least one non-wage benefit. Its definition is broad: it includes employer contributions to Employment Insurance and the Canada or Quebec Pension Plan and leave entitlements, so the figure does not mean 94.6% have an employer pension or health plan.

The Job Bank figures shown here are hourly wages. At the Canada median of $37.00, a full year of 35 to 40 hours a week works out to about $67,340 to $76,960 before tax (our arithmetic: hourly wage times weekly hours times 52 weeks). Overtime, shift premiums and time off without pay will move a real pay cheque up or down.

Job Bank's published three-year outlooks for each province and territory, updated 10 December 2025:

Over a longer period, the Canadian Occupational Projections System, as quoted by Job Bank, expects this occupation to face a moderate risk of labour shortage nationally from 2024 to 2033. About 88,500 people worked in it in 2023, and the median retirement age in 2023 was 63.0. Job Bank also gives 36% of workers as aged 50 or over. Those are reasons demand for new millwrights may hold up; they are not a promise of a job in any one town or plant.

The work is changing too. The Red Seal standard points to more automation and robotics in plants, smart sensors and monitoring systems, and predictive maintenance, where reading equipment data and graphs helps spot failures before they happen. With experience, the standard says, millwrights may specialise in vibration analysis, thermography, tribology (fluid analysis) or laser and optical alignment, or move up to mentor, supervisor, planner, superintendent, manager, instructor or trainer.

The Red Seal standard names mechanical aptitude, problem-solving, communication, job planning and organizing, and the ability to do trade calculations as key skills. Good coordination, manual dexterity and spatial visualization matter too, as does the ability to detect malfunctions through sensory tests, which the standard says are often confirmed by condition-based monitoring. The trade overlaps with steamfitter/pipefitters, instrumentation and control technicians, power engineers, welders, machinists and industrial electricians.

Job Bank's summary of the National Occupational Classification says completion of secondary school and training courses or a vocational program is usually required. To be eligible for trade certification you usually need either a three- to four-year apprenticeship or over five years of work experience plus industry courses in industrial machinery repair or millwrighting. The usual path looks like this:

Hours, levels and school rules differ by province, so check with your own province's or territory's apprenticeship authority before you plan your training.

If you have years of experience in the trade but never did an apprenticeship, there is a second route. Job Bank's summary lists over five years of work experience plus industry courses in industrial machinery repair or millwrighting as the usual requirement on that route; your apprenticeship authority decides whether you qualify. Red Seal calls people on this route trade qualifiers; British Columbia calls it challenging the certification exam. Red Seal says each province's or territory's apprenticeship authority decides who can write the exam, that the rules differ for apprentices and trade qualifiers, and that you must be experienced in the full scope of the trade. SkilledTradesBC, for example, describes a path for people with experience but no Canadian certification to challenge the certification exam, and Skilled Trades Ontario has a Trade Equivalency Assessment for experienced workers.

Not everywhere. Job Bank's summary of the National Occupational Classification says industrial mechanic (millwright) certification is "available, but voluntary, in all provinces and territories", and Skilled Trades Ontario calls the trade non-compulsory in Ontario. Ask your provincial or territorial authority what applies where you work.

The Red Seal is not a separate licence. Red Seal says tradespeople who pass the Red Seal exam receive a Red Seal endorsement on their provincial or territorial trade certificate. It shows you have the knowledge required by the national standard for the trade, and Red Seal says it "facilitates labour mobility" between provinces. Holders may use the letters RSE (Red Seal Endorsement) after their name. On its own, Red Seal adds, the endorsement does not mean a province has certified you to practise the trade; that is your provincial certificate.

The Industrial Mechanic (Millwright) trade has been designated Red Seal since 1964 and is Red Seal in every province and territory. Note that Red Seal says the current exams are still based on the previous standard (2017); exams based on the 2026 standard are under development.
