Your house has been running on the same electrical panel since the day the keys changed hands. The breakers trip a little more often now. The lights dim when the dryer kicks on. Maybe a buyer’s inspector flagged the panel during a sale last fall. These signs add up, and ignoring them gets expensive in ways most people do not see until it is too late.
A panel that is undersized or aged out is one of the more common fire risks in Ontario homes. The Electrical Safety Authority tracks these incidents every year, and the numbers are not small. Old aluminum wiring, undersized service, and worn breakers can sit quietly for decades. Then something goes wrong all at once.
Here is what a real panel upgrade or rewire involves when a qualified North Bay electrician handles it.
The First Visit
Before any tools come out, the electrician walks through the property. They check the panel age, the service rating, the wiring type, and the load. Older homes around North Bay often still have 60-amp or 100-amp service. That is not enough for a modern kitchen, a heat pump, or an EV charger. The walkthrough takes about an hour. A clear quote should follow within a few days, with the scope spelled out in plain language.
What a Panel Upgrade Actually Looks Like
A standard upgrade from 100 amps to 200 amps usually takes one working day. Power is off for roughly four to eight hours while the swap happens. That lines up with guidance from licensed Ontario contractors. The crew disconnects branch circuits, removes the old panel, installs the new one, and reconnects each circuit with proper labelling. The utility cuts service at the meter and restores it once the work passes inspection.
Inside the new panel, you get more space for circuits. There is also room for AFCI and GFCI breakers where the 2024 Ontario Electrical Safety Code now requires them. The new panel adds capacity for future loads too. The 2024 OESC took effect on May 1, 2025, and it expanded protection rules across most rooms in a typical home.
The ESA Permit Is Not Optional
Every panel upgrade in Ontario triggers a notification with the Electrical Safety Authority. A licensed contractor files this before work starts. Permit fees for a panel upgrade fall in the $150 to $250 range depending on scope. An inspector visits during or after the work and confirms it meets code. You get an ESA certificate once it passes.
Skipping the permit is not a paperwork problem. It is an insurance problem. If a fire starts later and an investigator finds unpermitted work, the claim can be denied. Buyers’ inspectors also look for ESA certificates during a sale. Missing paperwork can break a deal or knock thousands off the price.
Rewires Are a Different Job
A panel swap fixes the front end of your electrical system. A rewire fixes everything downstream. Knob and tube, old aluminum runs, brittle insulation, and undersized circuits all live inside the walls. You do not see them until a renovation opens things up, or until a circuit starts arcing.
A full rewire in an older North Bay home can take one to two weeks. Time depends on size and access. The crew runs new wire to every room, replaces outlets and switches, and ties everything back to the new panel. Some work happens behind drywall, which means small access cuts that get patched after. Good crews leave the patching clean.
Partial rewires are common too. A kitchen renovation, a basement finish, or an addition often calls for new circuits without touching the rest of the house. The same code rules apply to the new work. The original wiring outside that scope stays as it is.
What Separates a Proper Job From a Cheap One
Cheap panel work shows up later. Loose connections, missing labels, undersized neutrals, and skipped permits all create problems that another electrician has to fix at the owner’s cost. A proper job leaves a labelled panel, a clean ESA certificate, tidy wire runs, and a written warranty on the workmanship.
Ask the contractor for their ECRA/ESA licence number before signing anything. It should appear on their truck, their estimate, and their invoice. If it is missing, walk away. Unlicensed work carries fines of up to $50,000 for individuals under Ontario regulation. The homeowner can be on the hook for the cleanup too.
Wrapping Up
Living in North Bay and the wider Nipissing District means dealing with cold winters and the occasional bad storm. The grid takes hits a few times a year. A modern panel with proper protection gives you a margin that an old fuse box cannot. The same goes for the wiring behind your walls.
If your panel is past its service life, or the lights still dim when the furnace fires up, the next step is a proper assessment from a licensed local team.
