Panel and service upgrade

Electrical panel upgrade in Montreal

Most people upgrade a panel because someone made them: the insurer wants the fuse box gone, or the heat pump installer says there’s no room. Here’s what the job looks like and what it costs.

Panel or full service upgrade?

Swapping the panel alone keeps your existing service, usually 100 amps. A service upgrade replaces everything from the weatherhead down: mast, cable, meter base and panel, and gets you to 200 amps. If you’re adding an EV charger or a heat pump to an all-electric house, the electrician will run a load calculation before recommending either. Ask for it if nobody mentions it.

Hydro-Québec handles the wires from the pole to your house and the meter itself. Everything after that point is yours. For a service upgrade, your electrician books a disconnect with Hydro-Québec, does the work, and Hydro-Québec reconnects. Lead time ranges from a few days to a few weeks depending on the season.

2026 price ranges, before tax

JobTypical range
Fuse box to breaker panel, same amperage$2,000 to $3,200
New 100 amp panel replacing an old one$1,800 to $3,000
Full 200 amp overhead service with panel$3,500 to $6,000
Duplex or triplex with several metersquoted on site, often $6,000+

Grouping jobs saves money. If an EV charger is on next year’s list, say so now and have the circuit planned with the panel.

Common questions

My insurer says the fuse panel has to go. How fast?
It varies by insurer, often a few weeks to a few months. Get the deadline in writing and pass it on to the electrician so they can schedule around it.
How long will the power be off?
Four to eight hours for a panel swap. For a full service upgrade, about a day, plus however long Hydro-Québec takes to come back and reconnect.

Power out, burning smell, breaker keeps tripping?
