STRAIGHT ANSWERS
Common questions about electrical work in Ottawa
Short, factual answers: no sales pitch. If your question isn't here, call and ask.
Do I need an ESA permit for electrical work in Ontario?
Most work beyond simple fixture replacement requires notification to the Electrical Safety Authority. Panel changes, service upgrades, new circuits, and EV charger installations all do. As a licensed contractor we file the notification and arrange the inspection as part of the job. You do not need to contact ESA yourself.
How do I check that an Ottawa electrician is licensed?
Every legitimate electrical contractor in Ontario holds an ESA/ECRA licence number and must display it. Ours is #7000302, and you can verify it against the ESA contractor directory. If a contractor cannot give you a number, they are not licensed to do the work.
What does a 200A service upgrade cost in Ottawa?
It depends on whether the service is overhead or underground, where the panel sits, the condition of the mast and meter base, and whether grounding has to be brought up to current code. We measure on site and quote the full scope in writing - permit, ESA inspection, and Hydro Ottawa coordination included - so there are no additions later.
How long does a panel change take?
A straightforward residential panel change is typically completed in one day, with power off for part of it. Service upgrades that involve the utility can take longer to schedule because the disconnect and reconnect must be coordinated with Hydro Ottawa.
Is aluminum wiring a problem in older Ottawa homes?
Aluminum branch wiring was common in homes built between roughly 1965 and 1978 and is not inherently unsafe, but the connections can loosen and overheat over time. Many insurers now require remediation or a certified inspection. Copper pigtailing with approved connectors is the standard fix and is what most insurers accept.
Can you install a Level 2 EV charger in my garage?
In most cases yes. The deciding factor is whether your existing service has spare capacity: a load calculation tells us that. If it does not, the charger install is usually paired with a service upgrade. Both are work we do, and we quote them together.
