Straight answers
The questions people ask most about qualifying as, and practising as, an electrical engineer in Ontario. Answered straight, with links to the official bodies.
Building services (MEP) is the steady consulting work — power, lighting, fire alarm, low-voltage for buildings. Power systems is the higher-voltage grid and utility world. Renewables/electrification (solar, storage, EV) is the fastest-growing area and where demand is hottest right now. Building services has the clearest path to owning a firm; renewables has the momentum. Many electricals end up touching several over a career.
An electrical engineer (P.Eng) designs and stamps a building's electrical systems — power distribution, lighting, fire alarm, low-voltage. An electrician (the 309A compulsory trade) installs them on site. They're separate careers with separate credentials (PEO for the engineer, ESA/Skilled Trades Ontario for the electrician), different training, and different day-to-day work. People confuse them constantly, but one designs and the other builds.
There's a real case for it. EV charging, solar, battery storage, the electrification of heating (heat pumps), grid upgrades, and data-centre demand are all expanding electrical engineering work simultaneously — the whole economy is electrifying, and that's structural, not a fad. If you want a building-services discipline with strong long-term tailwinds, electrical is exceptionally well-positioned.
Mostly office design and coordination, with site visits for reviews and commissioning — similar to mechanical. The renewables and power sides can involve more field and utility-coordination time. If you want predominantly outdoor work, this isn't it; if you want analytical design with periodic site involvement and a future-facing field, it fits well.
Both are core MEP disciplines with similar pay and strong demand. Electrical has the electrification growth story (EV, solar, storage, smart buildings, data centres); mechanical has the HVAC/decarbonization story (heat pumps, net-zero). Choose by which systems genuinely interest you — electrons or air and water. Both have excellent prospects; electrical arguably has the stronger current momentum.
As good as it gets in building services. Demand is strong now and structurally rising as everything electrifies — and electrical engineers are in short enough supply that the renewables and power sides are actively competing for talent. Pay (EIT $62k–76k, P.Eng $88k–110k, principal $135k+) sits at or just above the engineering average, with the electrification specialties commanding premiums.

To stamp electrical designs and offer them to the public, yes — you need a P.Eng from PEO, practising within your competence. This is the design discipline, separate from the electrical contracting licence (ECRA/ESA) the trade side holds.
Hold (or employ) a P.Eng, obtain a PEO Certificate of Authorization with professional liability insurance, and incorporate. Work flows from architects and developers; pairing electrical with mechanical (full MEP) capability is a common way to grow.
Regulated professionals (architects, engineers) can often form a professional corporation, which carries specific naming and ownership rules and ties to your regulator's firm authorization. Unregulated professionals (quantity surveyors, project managers) incorporate like any business. Either way, incorporating limits personal liability and can reduce tax once you are profitable — confirm the right structure with your regulator first.
Professional liability (errors & omissions) insurance is the core coverage — it responds to claims from your advice, designs, or certifications, and is a firm-authorization requirement for regulated professions. Add commercial general liability, and cyber/contents coverage for your office.
Yes — professional services are HST-taxable in Ontario. You must register for and charge HST once revenue exceeds $30,000 over four consecutive quarters, and many register sooner to claim input tax credits on software, equipment, and office costs.
