Not every renovation requires a new panel, but many do, and the answer depends on the scope of your project and the condition of your existing panel. Here is how to think about it, from the licensed electricians at EZSMART, serving Toronto and the GTA.
A licensed electrician performs a load calculation to determine definitively whether your panel supports the renovation. This is more reliable than guessing based on panel size alone. If an upgrade is needed, panels from manufacturers like Eaton or Square D are standard replacements.
If a panel upgrade is needed, doing it as part of the renovation is more efficient than waiting until after the project is done. It coordinates with the overall project timeline and avoids duplicated work. Panel upgrades typically take a day and require utility service disconnection, which your electrician coordinates.
Panel upgrades require an ESA permit and inspection through the Electrical Safety Authority. Your licensed electrical contractor handles this.
How do I know if my panel has enough slots for new circuits?
A licensed electrician can assess this quickly during a project quote.
Is it worth upgrading to a 200 amp panel proactively?
For older homes with 100 amp panels, and especially those adding EVs or major additions, often yes.
Can I do part of a renovation before deciding on a panel upgrade?
Yes, though it is usually more efficient to know the panel plan before starting circuit work.
