Expert Opinion

If you want to be an Electrical Engineer in high-voltage power systems in Ontario, prioritize three things early: co-op experience, power-specific coursework, and professional networking.

  • Choose a CEAB-accredited Electrical Engineering program with electives in power systems, machines, and protection. If you’re coming from a technologist route, look for degree-bridging options and seek co-op to gain utility experience.
  • Target co-op or internships with utilities (Hydro One, Toronto Hydro, Alectra), major engineering firms (EPCs/consultants), or manufacturers (GE, Siemens). Real-world exposure to substations and protection testing is invaluable.
  • While in school, learn at least one industry tool (CYME/ETAP/PSSE/PSCAD) and get comfortable with AutoCAD/MicroStation and Python/MATLAB for Automation and reporting. Build a small portfolio (studies, settings examples, drawings) to show during interviews.
  • Join IEEE Power & Energy Society (PES) and attend local events (student branches and Ontario sections). Volunteer in a PEO chapter to meet mentors and potential supervisors. OSPE events also help you learn about policy and the broader energy landscape.
  • For international engineering graduates, engage PEO early to confirm your academic assessment and sign up for the EIT program. Proactively seek a P.Eng. mentor to guide your Canadian experience and references.

The Ontario grid is changing quickly with distributed energy, electrification, and renewables. If you learn continuously and stay safety-focused, you’ll be well-positioned for a long, meaningful career.

FAQ

Do I need a P.Eng. to work as an Electrical Engineer in high-voltage power systems at a utility?

To independently practice engineering and take legal responsibility for designs or decisions in Ontario, you must be licensed by Professional Engineers Ontario (PEO) as a P.Eng. Some junior roles (EIT) and analyst positions allow you to work under the supervision of a P.Eng. while you complete the licensing requirements. Learn more: https://www.peo.on.ca

Can I move into a high-voltage utility engineering role from an Electrical Engineering Technology advanced diploma?

Yes—many technologists transition successfully. A technologist diploma can lead to roles in protection and control, testing, drafting, and commissioning. To become a P.Eng., you’ll need a recognized engineering degree (or PEO-confirmed equivalency) and the required experience. Some colleges offer bridging or degree-completion pathways to a B.Eng./BASc. Co-op experience and strong skills in protection, SCADA, and substation design help you stand out.

What extra certifications or Training help in Ontario utility roles?

Utilities value training and familiarity with:

  • Utility Work Protection Code (UWPC)
  • Arc-flash safety, lockout/tagout, WHMIS, and first aid/CPR
  • Ontario Electrical Safety Code (OESC) knowledge via ESA: https://esasafe.com/industry/oesc/
  • Software training (CYME/ETAP/PSSE/PSCAD), AutoCAD/MicroStation
  • For project roles, PMP can help, though it’s not required for engineering licensure.

Employers often provide in-house training and vendor courses (e.g., relay manufacturer schools).

What organizations and events should I join in Ontario to network in power systems?

Attending technical seminars, factory acceptance tests, and utility-hosted sessions will expand your knowledge and visibility.
