Electrical Panel Upgrade in Markham
Not every Markham home has the spare capacity to add a charger, and that is where a panel upgrade comes in. We check what your existing panel can handle before recommending one, so you only pay for an upgrade you actually need.
Older homes around Markham Village and Milliken sometimes run a 100A panel that is already close to full, leaving no room for a 40A or 48A charger circuit. In those cases we upgrade you to a 200A service so the charger has a safe, dedicated home without overloading the rest of the house.
We coordinate the service upgrade with Alectra Utilities, pull the permit, and book the inspection. The charger install happens alongside the upgrade, so you have one crew, one quote, and one visit rather than juggling separate trades.
The service change runs on a predictable rhythm. Alectra Utilities disconnects in the morning, our electrician replaces the panel and service equipment, and power is typically back by mid-afternoon. The ESA inspection follows, and in most cases the charger circuit goes in during the same project so you are not coordinating two separate timelines.
It is worth saying plainly that plenty of Markham homes do not need this. Newer builds in Cornell, Berczy Village, and Angus Glen often have 200-amp panels with room to spare, and in those cases we quote the charger and nothing else. Where an upgrade is genuinely required, usually on the older streets around Markham Village and Milliken, you will see the load calculation behind the recommendation before you approve anything.
