PLCs, automation, motor control, oil and gas work — the complete apprenticeship and career guide for 442A Industrial Electricians in Canada.
Red Seal describes industrial electricians as installing, maintaining, testing, troubleshooting, servicing and repairing industrial electrical equipment and associated electrical protection and controls, such as motors, generators, pumps and lighting systems. Job Bank's industrial electrician medians are $44.00/hr in Alberta, $45.00/hr in British Columbia and $40.50/hr in Ontario, with Alberta's high at $68.00/hr (wages updated November 2025).
This guide explains what industrial electricians do, how the 442A apprenticeship works, wages by province and period, how 442A differs from 309A, and the specialty career paths that can take a journey industrial electrician into automation, oil and gas, and instrumentation roles.
Most pay figures on this page are Government of Canada Job Bank data for everyone working in the occupation, not only certified tradespeople. The 442A exam is 100 questions in 4 hours and the pass mark is 70%, which is 70 correct.

| Aspect | 442A Industrial Electrician | 309A Construction Electrician |
|---|---|---|
| Red Seal description | Install, maintain, test, troubleshoot, service and repair industrial electrical equipment and associated electrical protection and controls | Plan, design, assemble, install, alter, repair, inspect, verify, commission, connect, operate, maintain and decommission electrical systems |
| Employers (NOC 2021) | Electrical contractors and maintenance departments of factories, plants, mines, shipyards and other industrial establishments | Electrical contractors and maintenance departments of buildings and other establishments, or self-employed |
| Exam blocks (red-seal.ca) | Six Major Work Activities, including process control systems (17 of 100 questions) | Five Major Work Activities; automated control systems are one task (D-25, 3 questions) |
| Wage (Job Bank, Canada, wages updated November 2025) | $28.00–$54.00/hr, median $42.00 (NOC 72201) | $20.00–$48.00/hr, median $35.00 (NOC 72200) |
Ontario and British Columbia run the two as separate apprenticeship programs. Alberta's Electrician apprenticeship covers both, and since May 1, 2026 Alberta has issued both a Construction Electrician and an Industrial Electrician journeyperson certificate to people who complete it, with the option to write one or both Red Seal exams (Alberta Tradesecrets).
Motors are the workhorses of industrial facilities, and maintaining them is a core industrial electrician function. This includes megohm (insulation resistance) testing of motor windings, vibration analysis, bearing inspections, alignment checks, and motor rewind assessment. Industrial electricians must understand motor nameplate data, NEMA frame sizing, duty cycle ratings, and how to match motors to Variable Frequency Drive (VFD) controllers. Troubleshooting a motor system means tracing the full electrical path: from disconnect → contactor → overload relay → VFD → motor → encoder feedback — and identifying where the fault lies using multimeters, clamp meters, and oscilloscopes.
Programmable Logic Controllers (PLCs) are the brains of automated industrial systems, and 442A industrial electricians are expected to understand PLC operation, read ladder logic diagrams, and perform basic troubleshooting. Major PLC platforms encountered in Canadian industry include Allen-Bradley (Rockwell), Siemens, Mitsubishi, and Schneider Electric. Industrial electricians typically do not write complex PLC programs from scratch — that is generally the automation engineer's role — but they must be able to go online with a PLC, monitor I/O status, interpret logic to understand system behavior, force inputs/outputs for testing, and recognize faults in PLC-controlled sequences.
Industrial electricians frequently work on 4–20 mA instrumentation loops connecting field instruments (pressure transmitters, flow meters, temperature sensors, level switches) to control systems (PLCs, DCS, SCADA). Understanding loop wiring, two-wire vs. four-wire instruments, 24 VDC vs. 120 VAC instrument power, and interpreting P&ID (piping and instrumentation diagram) drawings is essential for industrial electrical work. Calibration of field instruments, particularly on process control loops, requires specialized knowledge beyond the standard CEC training.
Many industrial facilities operate at medium voltage (for example 4.16 kV or 25 kV) or higher. Industrial electricians may be responsible for operating high-voltage switches, maintaining medium-voltage motor control centers (MCCs), performing high-potential (hipot) testing on cables, and executing lockout/tagout procedures on high-energy systems. High-voltage work requires additional training (HV switching certificates, specifically authorized procedures).
Program length depends on the province. In Ontario, the 442A apprenticeship is 7,950 hours of on-the-job training (about 5 years) plus 1,050 hours of technical training across 4 levels (Skilled Trades Ontario). British Columbia requires 6,000 hours of work-based training plus 40 weeks of technical training over 4 years (SkilledTradesBC). Alberta's Electrician apprenticeship, which covers industrial electrician training, runs 4 periods of about a year each: 1,560 hours of work experience and 8 weeks of classroom instruction in each of periods 1 and 2, then 1,500 hours and 10 weeks in each of periods 3 and 4 (Alberta Tradesecrets).
| Period | OJT Hours (Alberta) | Technical Training (Alberta) | Example Topics (not from Alberta’s course outline) |
|---|---|---|---|
| Period 1 | 1,560 hrs | 8 weeks | Electrical safety, basic wiring, motor nameplate data, CEC fundamentals, WHMIS, lockout/tagout |
| Period 2 | 1,560 hrs | 8 weeks | Motor control circuits (starters, contactors, overloads), transformers, power systems, single-line diagrams |
| Period 3 | 1,500 hrs | 10 weeks | VFDs, PLCs (ladder logic basics), instrumentation (4–20 mA loops), P&ID interpretation |
| Period 4 | 1,500 hrs | 10 weeks | Advanced PLC troubleshooting, SCADA/DCS overview, medium voltage systems, power quality, pre-exam review |
| Level | Alberta (Electrician program; Alberta Tradesecrets, checked September 2026) | BC | Ontario |
|---|---|---|---|
| Period 1 | At least 50% of journeyperson rate | Check provincial rules and your agreement | Check provincial rules and your agreement |

| All industrial electricians, NOC 72201 (Job Bank median and range, wages updated November 2025) | $44.00/hr ($25.00–$68.00) | $45.00/hr ($35.90–$54.95) | $40.50/hr ($29.00–$48.00) |
Job Bank's Alberta high for industrial electricians, $68.00/hr, is the highest provincial figure (wages updated November 2025); allowances and overtime on turnaround work depend on the employer and agreement.
The Red Seal 442A Industrial Electrician interprovincial exam:
Job Bank lists construction (28%) and oil and gas extraction (23%) as the largest sectors for industrial electricians in Alberta, followed by support activities for mining, oil and gas (6%) and machinery manufacturing (6%). It rates Alberta's 2025–2027 outlook as moderate: employment growth will lead to a few new positions, and a moderate number will open through retirements (outlooks updated December 10, 2025).
In British Columbia, Job Bank lists construction (22%), wood product manufacturing (12%), mining and quarrying (12%) and paper manufacturing (8%) as the largest sectors for industrial electricians. It rates the outlook as moderate, expects employment growth to lead to a moderate number of new positions and several to open through retirements, and notes that employment opportunities tend to be more favourable during the summer months.
In Ontario, motor vehicle, body, trailer and parts manufacturing is the largest sector for industrial electricians (34%), ahead of construction (13%) and food, beverage and tobacco product manufacturing (9%). Job Bank sees opportunities to support upgrades and maintenance of electrical equipment in the province's large manufacturing base, but says weak business conditions in manufacturing, including automotive and steel production, may constrain prospects; it expects an employment decline, with several positions opening through retirements.
In Saskatchewan, mining and quarrying is the largest sector for industrial electricians (37%), ahead of construction (26%). Job Bank rates the outlook there as good and expects investments in industrial projects and mining and improved commercial construction to increase demand. In northern Ontario, it calls the mining industry a major source of work for industrial electricians.
Industrial electricians who develop strong PLC programming skills (Rockwell Studio 5000, Siemens TIA Portal, Wonderware SCADA) can transition into automation specialist roles, where pay depends on the employer and role. Automation specialists design and commission new automated systems, modify existing PLC code to improve performance, and troubleshoot complex control failures — work that requires both deep electrical knowledge and programming competency.
The 447A Instrumentation and Control Technician trade overlaps significantly with advanced 442A work. Some industrial electricians pursue dual certification or transition into instrumentation roles, which focus on calibration and maintenance of process measurement instruments (pressure, flow, temperature, level), control valve maintenance, and DCS/SCADA system support. Instrumentation technicians earn rates comparable to industrial electricians — Job Bank lists industrial instrument technicians (NOC 22312) at $31.00–$65.78/hr, median $46.00, against a $42.00 median for industrial electricians (Canada, wages updated November 2025).
Industrial electricians with additional high voltage training and qualifications (typically through employers or through programs like the Power Line Technician components) can work on medium and high voltage systems: 4.16 kV motor buses, substation switching, cable testing, and transformer maintenance. The additional qualifications and safety responsibility can bring higher pay, depending on the employer.
Red Seal's 442A standard says industrial electricians conduct preventative and predictive maintenance programs; it lists vibration analysis among field assessments, and thermographic imaging devices and power quality analyzers among diagnostic and test equipment.

Start 442A Practice →They are two separate Red Seal trades. Red Seal describes construction electricians' electrical systems as serving residential, agricultural, commercial, institutional, industrial, transportation and entertainment environments, and industrial electricians as installing, maintaining, testing, troubleshooting and repairing industrial electrical equipment and its protection and controls, such as motors, generators, pumps and lighting systems. The 442A exam has a 17-question process control block (I/O devices, automated control systems, and pneumatic and hydraulic controls); the 309A exam has no such block, though it gives automated control systems one 3-question task (D-25). Industrial electricians are employed by electrical contractors and maintenance departments of factories, plants, mines, shipyards and other industrial establishments (NOC 2021), and Job Bank lists construction as their largest sector in Alberta (28%) and British Columbia (22%). Ontario and British Columbia run the two as separate apprenticeship programs, while Alberta's Electrician apprenticeship covers both.
Job Bank rates the 2025–2027 job outlook for industrial electricians (NOC 72201) as good in Newfoundland and Labrador, Nova Scotia and Saskatchewan, moderate in New Brunswick, Ontario, Manitoba, Alberta and British Columbia, and limited in Quebec; it is undetermined in Prince Edward Island and the territories (outlooks updated December 10, 2025). In Alberta, British Columbia and Saskatchewan it expects employment growth and retirements to open positions, and in Saskatchewan investments in industrial projects and mining to increase demand. In Ontario it expects an employment decline, with positions still opening through retirements, and says weak business conditions in manufacturing, including automotive and steel production, may constrain prospects. Nationally, Job Bank projects a moderate risk of labour shortage over 2024–2033.
Requirements vary by province. In Alberta, Electrician is a designated compulsory trade whose apprenticeship covers both Construction Electrician and Industrial Electrician education — to perform its restricted activities you must be a registered apprentice, a certified journeyperson or hold a recognized trade certificate — and since May 1, 2026 Alberta has issued both a Construction Electrician and an Industrial Electrician journeyperson certificate to people who complete that apprenticeship, with the option to write one or both Red Seal exams. In BC, Industrial Electrician is a Skilled Trades Certification (compulsory) trade under SkilledTradesBC. In Ontario, the 442A Industrial Electrician is a non-compulsory trade administered by Skilled Trades Ontario. The Red Seal endorsement is earned by passing the interprovincial exam, and Red Seal says the endorsement facilitates labour mobility. red-seal.ca's designation list for Industrial Electrician names British Columbia, Manitoba, New Brunswick, Newfoundland and Labrador, Nova Scotia, the Northwest Territories, Ontario, Prince Edward Island, Quebec and Yukon; it does not list Alberta, Saskatchewan or Nunavut.
