PLCs, automation, motor control, oil and gas demand — the complete apprenticeship and career guide for 313A Industrial Electricians in Canada.
The 313A Industrial Electrician is one of Canada's most technically complex and highest-compensated skilled trades. While the 309A Construction Electrician wires buildings, the 313A Industrial Electrician keeps industrial facilities running — maintaining motors, variable frequency drives, PLCs, SCADA systems, instrumentation loops, and high-voltage switchgear in environments where production downtime costs thousands of dollars per hour. In Alberta's oil sands, BC's LNG facilities, and Ontario's advanced manufacturing plants, experienced industrial electricians command $50–70/hr and are consistently among the highest-earning trades on site.
This guide explains what industrial electricians do, how the 313A apprenticeship works, wages by province and period, how 313A differs from 309A, and the specialty career paths that can take a journey industrial electrician into automation, oil and gas, and instrumentation roles.
The distinction between these two electrical trades is fundamental and frequently misunderstood:
| Aspect | 313A Industrial Electrician | 309A Construction Electrician |
|---|---|---|
| Primary work environment | Manufacturing plants, refineries, mines, oil sands, mills | Construction sites, commercial buildings, residential |
| Primary code | CEC + equipment-specific standards (NEMA, IEC, CSA) | Canadian Electrical Code (CEC) — installations in buildings |
| Focus | Maintenance, troubleshooting, automation, controls | Installation of new wiring systems |
| Key skills | PLCs, VFDs, motor control, instrumentation, HV switching | Conduit bending, panel wiring, load calculations, service entrance |
| Work schedule | Often rotating shifts (24/7 plant operations) | Typically day shift on construction projects |
| Wage (JM, typical) | $45–65/hr (Alberta oil sands up to $70) | $38–55/hr (BC/AB union rates) |
In some provinces, workers can hold both certificates (dual ticket), which significantly expands employment options. The two programs share electrical theory fundamentals but diverge substantially in technical content — industrial electricians learn significantly more about motor theory, PLC programming, industrial instrumentation, and process control systems, while construction electricians learn more about conduit systems, service calculations, and building code compliance.
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 313A 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 (4.16 kV, 13.8 kV, 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) and commands premium wages. In Alberta's oil sands operations, HV-qualified industrial electricians are particularly well compensated.
The 313A Industrial Electrician apprenticeship is typically a 4-period program with approximately 2,000 on-the-job hours per period (total ~8,000 hours), plus 6–8 weeks of technical training per period.
| Period | OJT Hours | Technical Training | Key Content |
|---|---|---|---|
| Period 1 | ~2,000 hrs | 6 weeks | Electrical safety, basic wiring, motor nameplate data, CEC fundamentals, WHMIS, lockout/tagout |
| Period 2 | ~2,000 hrs | 6–8 weeks | Motor control circuits (starters, contactors, overloads), transformers, power systems, single-line diagrams |
| Period 3 | ~2,000 hrs | 6–8 weeks | VFDs, PLCs (ladder logic basics), instrumentation (4–20 mA loops), P&ID interpretation |
| Period 4 | ~2,000 hrs | 6–8 weeks | Advanced PLC troubleshooting, SCADA/DCS overview, medium voltage systems, power quality, pre-exam review |
| Level | Alberta | BC | Ontario |
|---|---|---|---|
| Period 1 | $26–30/hr | $26–29/hr | $24–28/hr |
| Period 2 | $30–36/hr | $29–34/hr | $27–32/hr |
| Period 3 | $35–42/hr | $33–40/hr | $31–38/hr |
| Period 4 | $40–48/hr | $38–46/hr | $36–44/hr |
| Journeyperson | $48–65/hr | $45–60/hr | $42–58/hr |
Oil sands positions in Alberta (Fort McMurray, Strathcona Industrial Heartland) represent the highest wages in the country for industrial electricians — experienced journeypersons on turnaround projects can earn $65–70/hr plus camp accommodation, meals, and travel allowances, pushing total compensation well above $150,000 annually for those willing to work remote rotations.
The Red Seal 313A Industrial Electrician interprovincial exam tests theory and application across the full scope of industrial electrical work:
Alberta's oil sands represent the single largest employer of industrial electricians in Canada. Surface mining and in-situ (SAGD) operations require thousands of industrial electricians for both capital project construction and ongoing maintenance. Major operators (Syncrude, Suncor, Canadian Natural Resources, Cenovus) and their maintenance contractors (Keyera, Graham, PCL Industrial) hire industrial electricians for both direct employment and turnaround project work. With oil sands production expected to remain commercially significant through 2040+, this sector provides long-term employment security for 313A-certified electricians willing to work in northern Alberta.
LNG Canada's Kitimat facility, British Columbia's second LNG terminal projects, and the Alberta Industrial Heartland's petrochemical cluster all employ large numbers of industrial electricians. LNG facilities are particularly labour-intensive because they operate at cryogenic temperatures and high pressures, requiring specialized electrical equipment (explosion-proof motors, classified area wiring, hazardous location equipment) that demands industrial electricians with deep knowledge of Class I/II/III area classification under the CEC.
New manufacturing investment in Canada — EV battery gigafactories (Ontario, Quebec), steel mills, food processing, and pharmaceutical manufacturing — consistently requires industrial electricians both for construction commissioning and ongoing maintenance. As manufacturing becomes more automated, the PLC and robotics skills of industrial electricians become increasingly valuable. Facilities transitioning from relay logic to modern PLC/DCS systems create significant demand for industrial electricians who can commission and maintain automated systems.
Mining operations across BC, Ontario's Ring of Fire, Saskatchewan's potash mines, and Newfoundland's nickel operations all require industrial electricians. Mining electrical work involves high-voltage distribution, large motor drives for conveyor and crusher systems, diesel-electric haul trucks, and increasingly, remote monitoring and automation systems. Underground mining positions typically pay significant safety premiums on top of already-high industrial wages.
Industrial electricians who develop strong PLC programming skills (Rockwell Studio 5000, Siemens TIA Portal, Wonderware SCADA) can transition into automation specialist roles that command $55–80/hr. These positions blur the boundary between trades and engineering technologist roles. Formal certification in specific PLC platforms (Rockwell Certified Systems Integrator, Siemens Certified Programmer) significantly increases marketability. 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 430A Instrumentation and Control Technician trade overlaps significantly with advanced 313A 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 in oil and gas earn comparable rates to industrial electricians ($45–65/hr) and are in chronic short supply across the petrochemical sector.
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 and 13.8 kV motor buses, substation switching, cable testing, and transformer maintenance. HV-qualified industrial electricians are particularly sought in oil sands, utilities, and mining, where most process motors operate at medium voltage. The additional qualifications and safety responsibility command $5–15/hr premium over base industrial electrician rates.
Industrial facilities are increasingly adopting condition monitoring and predictive maintenance programs that require industrial electricians with skills in vibration analysis, thermography (infrared camera inspection), power quality analysis, and partial discharge testing. Certified reliability technician (CRT) and vibration analyst certifications (Mobius Institute, ISO category I–III) add significant value to a journeyperson's resume. Reliability-focused industrial electricians often move into maintenance planning and reliability engineering roles with salaries reaching $95,000–$125,000 annually.
