Estimated Costs for Fuse Box Replacement and Panel Upgrade in Ontario

Advantage of Getting a New Breaker Panel Installed

A new breaker panel provides many benefits over a fuse box in terms of safety, efficiency, and value of the property:

Better Safety: New breaker panels have advanced protection devices, including Residual Current Devices (RCDs) and Arc Fault Circuit Interrupters (AFCIs), that protect against shocks and electrical arc fault fires. New breaker panels perform at a higher overall safety standard.


Better Capacity: It is now standard in Canada to have 200-amp panels which can carry all current appliances, central A/C, and now even chargers for cars, eliminating the need for user power load control, and result in fewer trip circuits.


Increase Value: Having an updated electrical system, to code, is a significant selling feature for selling a home. Most people prefer a house that does not require much demo and reconstruction, and an upgraded system with a high level of safety and efficiency will increase the value of the home.

Comprehensive Cost Analysis and Influencing Factors

The price of replacing a fuse box with a breaker panel in Canada will also vary extensively, $1,000-$12,800+, depending on the specifics of the installation. The job cost can fluctuate significantly depending on many factors. Identifying those factors is essential for suitable budgeting and avoiding financial shocks.

Overview of Costs in Ontario

In Ontario, the average cost to change a fuse box to a breaker panel is estimated to range from $1,900 – $5,800 CAD. The typical cost of moving from a 100-amp service to a 200-amp service, which is often the case for older homes, is between $1,800 – $2,200 in Ontario. In a major city like Toronto, the same job can be anywhere from $2,000 – $5,000 and beyond.

This spans an incredibly broad spectrum of cost, meaning that the primary price is only one part of the total cost. An initial estimate that is significantly less than the average market cost of a certain project may very well not include a number of ancillary and “unexpected” costs that any courteous and responsible electrician would include in their proposal. For example, $2,000 may be a low initial price, but now the electrician wants to charge you extra to run the cable out onto your front lawn OR they want to charge you for how “unforeseen” it is that your grounding system on the house needs upgrading.

Key Factors Determining the Final Price

  1. Electrical Panel Capacity (Amperage): The cost will increase with a higher amperage panel. An upgrade from 200 to 400 amps, usually for larger homes with high electrical loads, will be in the range of $3,500 to $12,000. 
  2. Labor Costs: Electricians typically charge per hour between $70 and $110 in the Greater Toronto Area (GTA). The complexity of the job will oftentimes affect the number of labor hours. Complicated access to the panel or the existing wiring may complicate the install and add considerable time to the job.
    Permits and Inspections: To replace your electrical panel in Ontario, you will need to legally apply for a permit from the Electrical Safety Authority (ESA). Permits are issued to ensure the work performed is safe and follows the Ontario Electrical Safety Code (OESC). The ESA permit isn’t a fixed fee and can be between $65 and $500.
    Any cost of permit found elsewhere, such as “Hamilton, NJ” (located in New Jersey, USA) does not relate to Ontario or the city of Hamilton, Canada, and should not be considered. This information does not follow the local law or governing body in Ontario, and should be disregarded. You should always rely on reputable information sourced to Ontario law, when considering costs.

Ancillary Costs

These expenses are frequently overlooked in initial estimates but can greatly affect the ultimate cost of the project as described below:

Rewiring: Old and incompatible wire to connect to the new panel may require rewiring. If you’re just rewiring parts of your home, it can cost you anywhere from $500 up to $2,000. If your entire house needs to be rewired, it’ll cost you anywhere from $3,850 up to $10,300.


Relocation of the Panel: If you decide to relocate the panel, you can expect to pay about $1,000 up to $1,500 extra.


Grounding System Upgrade: The Ontario Electrical Code requires you to upgrade your grounding wire which can cost you an additional $100 up to $200. The cost of materials for copper grounding wire is about $3.69 to $4.79 per meter.
Utility Company Service Upgrade: In some cases, your local utility company (e.g., Toronto Hydro) will need to upgrade the lines to your home which can cost anywhere from $500 to $1,500 or more. If you’re in Toronto, the cost for getting the power cut off and reconnected by local utilities is usually somewhere between $300 and $678.

The Replacement Process and Safety Considerations

Changing out an electrical panel is an very difficult and extremely unsafe task that must only be carried out by a licensed and insured electrician. In Ontario, this is required by law, regulated by the Electrical Safety Authority (ESA), to protect the property owner and ensure compliance with electrical safety regulations.

Step-by-Step Electrical Panel Replacement Process

  1. Get a Written Quote: A qualified electrician should provide a formal, detailed, and transparent written quote that encompasses all potential costs associated with the type of panel (along with the material, labor costs, and permits).
    Get a Permit: The electrician will request the ESA permit on your behalf. This permit provides that the work will be completed with the standards and local regulations.
    Work with the Utility Company: The electrician will liaise with the local utility company to temporarily disconnect the power to your home.
    Install the New Panel: The electrician will remove the old panel and the new breaker panel and all of the wiring needed. That can take from a few hours to one or two days.
    Final Inspection: After the electrician has completed the work, an ESA Inspector will go to confirm the work has been completed safely and is to code. When approved, a Certificate of Inspection will be issued.

Why Is Attempting a DIY Job a Serious Hazard?

Working with high-voltage electrical systems is a serious risk to life. Attempting to replace an electrical panel without proper training and equipment carries the following problems:

Risk of Electric Shock and Death – An electric panel is connected directly to the home’s main power, so a single mistake has the potential for instant death.

Fire Risk – Improper wiring or not meeting safety code requirements can heat up wiring and start a fire.

Legal Violation and Voiding Insurance – In Ontario, unless you have a legal permit, it is illegal to do electrical work, and there are large fines and legal issues involved. Furthermore, most home insurance companies, when there is an accident due to unlicensed work, will void the home insurance policy.

A Focused Look at the Specified Regions in Ontario

Availability and cost of electrical services will differ across the province of Ontario, specifically in the Greater Toronto Area (GTA) in said cities. Cities with higher density such as Toronto and Mississauga will be above average in service cost since the cost of living in Toronto and the rate of electrician labor are both higher.

Some single miscellaneous costs will specifically influence the cost of an activity, i.e., Toronto Hydro reconnection and disconnection fees for electricity.

In smaller cities, such as Oakville, Burlington, Newmarket, Ancaster, and Milton, you can expect fees to be around the same but with a little more flexibility and lenience. There can also just be differences based on the age of homes because older homes in certain cities will have more work to do in rewiring, and that is more expensive.

Having your service upgraded from a fuse box to a breaker panel by us equates to having space for future additions. This is to indicate that when you need to install a new circuit, when upgrading some part of your home like a kitchen or bedroom, or installing an EV charger, you will have the space to accomplish so. For example, in upgraded parts, you will often need new branch circuits with arc fault protection, which can be easily accommodated by a breaker panel. Conversely, a fuse box is generally packed and does not accommodate these types of upgrades.”
