Panel upgrades in Mississauga: what to expect
Most homes we open up in Mississauga are 1960s–90s subdivisions. Homes of this age commonly have 100 or 125 A services, or a 200 A panel that's simply out of breaker spaces.
Service upgrades in Mississauga need a disconnect and reconnect from Alectra Utilities. We file the ESA notification, book the utility, and on the day swap the panel, re-terminate every circuit and test before Alectra Utilities restores power — usually the same afternoon.
Adding a basement apartment is one of the most common reasons Mississauga homeowners call us about their panel: a second household means a second set of loads, and often a dedicated sub-panel.
Local notes: Mississauga
100 A services, big appliances. Large split-levels and two-storeys from the '70s and '80s are often on 100 A. Add an EV, central air and an induction range and that's where a load calculation — or an upgrade — comes in.
Aluminum wiring checks. If your home was built roughly between the mid-60s and late 70s, it's worth confirming what's in the walls. Pigtailing with approved connectors is often all that's needed.

Questions from Mississauga
How long does a panel upgrade take in Mississauga?
Usually one day on site with four to eight hours without power. Booking the Alectra Utilities disconnect typically takes one to three weeks.
Who handles the Alectra Utilities side?
We do. We book the disconnect and reconnect with Alectra Utilities and file the ESA permit — you don't need to call either.
Do all Mississauga homes need 200 A?
No. If you're only adding an EV charger, load management can often avoid an upgrade. We'll calculate your actual load first.
