What Most People Get Wrong About Panel Upgrades

The most common misconception about panel upgrades is that they're optional improvements rather than corrective work...

The corrective work isn't optional in any meaningful sense. The question is only whether you do it on your timeline or on the panel's timeline.

Electrical Panel Upgrade & Repair in Ontario: Frequently Asked

How do I know if I need a panel upgrade?
Common indicators include breakers tripping when multiple appliances run together, a 100-amp service in a home with significant modern load, plans to add an EV charger or central AC, a panel brand on the recall list, or an insurance review flag.
How long does a 200-amp upgrade take?
Most upgrades in Ontario take one to two working days, with a planned utility outage of several hours during the swap.
Can I keep my existing breakers when the panel is upgraded?
Generally, no. Modern panels require breakers UL-listed for that specific panel.
Does an upgrade require a permit and inspection?
Yes. Panel work in Ontario requires both a permit and an inspection sign-off. We handle the entire process.
Can you give me a price over the phone?
For a panel job, no. A site visit takes 30 minutes and produces a real number you can rely on.
