Electrical Panel Upgrade: Signs Your Burlington-Area Home Needs One
A 100A panel was standard in Ontario homes built through the 1980s. A modern kitchen, a home office, central air, and an EV charger can push that same panel well past what it was ever sized to carry. We see this constantly across Burlington, Oakville, Milton, and Halton Hills, houses that were wired correctly for their era and just haven't kept pace with what a household runs today.
Five signs your panel is due for an upgrade
Breakers trip more than once a month. Especially the same one, especially under normal use like running the microwave and the kettle at once.
You still have a fuse box, not breakers. If you're replacing screw-in fuses instead of flipping a switch, your panel predates most of Ontario's current housing stock.
Buzzing, warm spots, or discoloration around the panel. Stop reading and call someone today, not next week.
You're planning an EV charger, a renovation, or a hot tub. Any of these adds real load. Worth checking capacity before you commit to the project, not after.
Your home is 30 to 40+ years old and has never been upgraded. Age alone isn't proof of a problem, but it's a reason to have someone check.
What the upgrade actually involves
We assess the existing panel and your household load first, most homes go from 100A to 200A, occasionally higher for larger properties or homes with a shop or secondary suite. We pull the ESA permit, coordinate the temporary disconnect with the utility, install the new panel, and reconnect. The Electrical Safety Authority inspects the finished work before we close out the job.
100A vs. 200A: what actually changes
It's not just a bigger number on the panel door. A 200A service gives you headroom for central air, an EV charger, a finished basement with its own circuits, and appliances that didn't exist when the house was built, all running at once without tripping anything. A 100A panel can handle a house from 1975. It usually can't handle that same house today, renovated and modernized.
Older neighbourhoods, older panels
This comes up most in specific parts of our service area: Old Milton and Timberlea, Old Georgetown and the heritage streets around Acton and Glen Williams in Halton Hills, and the older cores of Oakville and Burlington. Homes there were often built before central air was standard, let alone EV charging. We work around the character of an older home, we don't rip out anything that doesn't need to go, but the panel itself usually needs attention if it hasn't been touched since the house was built.
Why the ESA inspection matters more than people think
An upgraded panel without a passed ESA inspection isn't actually done, on paper or in practice. It matters when you sell the home (buyers' lawyers ask), it matters for your insurance (some policies flag panels over a certain age), and it matters because it's the only way to confirm the work was done to code. We pull the permit and get the inspection every time. No exceptions.
