EV charging • renovations • electrical equipment • growing demand
Do You Actually Need a 200 Amp Service Upgrade?
Not every home with a 100 amp service automatically needs to move to 200 amps. The right answer depends on your existing electrical demand, the equipment you want to add and how much capacity is available today.
A Level 2 EV charger can add a significant new electrical load, especially when combined with other large appliances.
Additions, basement renovations, kitchens and other projects can increase the amount of electrical demand placed on the home.
Heat pumps, electric ranges, dryers, hot tubs and other equipment can change the load requirements of the house.
If the existing 100 amp service has limited remaining capacity, an upgrade may provide the room needed for future electrical work.
Some homes can continue operating on a 100 amp service depending on the existing electrical load and what you are trying to add.
A 200 amp service upgrade should be based on what the home actually needs — not simply because the existing service says 100 amps.
What Actually Happens During a 100 Amp to 200 Amp Service Upgrade?
A 200 amp service upgrade is more than simply changing the panel. The exact scope depends on the existing service, meter setup, panel location and how power is supplied to the home.
Assess the Existing Service
We review the existing panel, service size, meter location, electrical demand and the work you are planning for the home.
Determine the Upgrade Scope
We determine what equipment and service work is required based on the existing setup and the new 200 amp service.
Complete the Panel & Service Work
The electrical service and panel are upgraded according to the actual project requirements, including any related service equipment.
Prepare the Home for Future Demand
Once complete, the home has increased electrical capacity for future loads such as EV charging, renovations and new equipment.
Some projects are straightforward, while others can involve additional service equipment, underground work, disconnects or other site-specific requirements.

How Much Does a 100 Amp to 200 Amp Upgrade Cost?
The cost of a 100 amp to 200 amp service upgrade in Mississauga depends heavily on the home's existing electrical service and how much work is required to complete the upgrade.
A straightforward setup can be very different from a property requiring additional service equipment, disconnects or underground work.
A very basic back-to-back 200 amp service and panel upgrade can start around this range when the existing setup allows for a straightforward installation.
More involved projects can cost significantly more depending on the existing service, property layout and additional work required to complete the upgrade.
What Can Change the Price of a 200 Amp Upgrade?
The current panel, meter and service arrangement can significantly affect the amount of work required.
Accessibility and the relationship between the panel, meter and incoming service can affect the installation.
Properties requiring underground service work or trenching can involve considerably more labour and scope.
Additional electrical equipment required for the new service can change the overall project cost.
Every home is different. Existing wiring, equipment and physical site conditions can affect the final scope.

100 Amp to 200 Amp Upgrade FAQ
Common questions homeowners ask us about 200 amp panel and electrical service upgrades in Mississauga.
01 How much does a 100 amp to 200 amp upgrade cost in Mississauga? +
A very basic back-to-back 100 amp to 200 amp panel and service upgrade can start around $2,500. More involved projects can reach $5,000+ depending on the existing service, disconnects, trenching or underground work, service equipment and other site conditions.
02 Does every home with a 100 amp service need to upgrade to 200 amps? +
No. A 100 amp service does not automatically need to be upgraded. The decision should be based on the home's existing electrical demand, available capacity and the equipment or renovations being planned.
03 Do I need a 200 amp service for an EV charger? +
Not necessarily. Some homes can install an EV charger while remaining on a 100 amp service, depending on the electrical load and available capacity. In some situations, a load-management solution may also be an option.
Learn About EV Charging With a 100 Amp Panel →04 What usually makes a 200 amp service upgrade more expensive? +
Cost can increase when the project requires additional service equipment, disconnects, underground work, trenching, difficult access or other changes to the existing electrical service.
05 Is a panel replacement the same as a 200 amp service upgrade? +
No. Replacing an electrical panel while keeping the existing service is different from increasing the home's electrical service capacity. A 100 amp to 200 amp upgrade can involve additional service equipment and work beyond the panel itself.

Homeowners may consider a 200 amp upgrade when adding larger electrical loads such as EV charging, electric appliances, heat pumps, renovations, additions or other equipment that increases household electrical demand.
