The electrical panel powers your entire home, including appliances, lighting, HVAC systems, and entertainment devices. A properly designed electrical system should provide reliable power without overloaded circuits or frequent breaker trips.
However, if you live in an older home or your household electrical demands have increased over the years, it may be time to consider an electrical panel upgrade or replacement. While upgrading your electrical panel is an investment, having the work completed safely by a licensed electrician, like the team at Ontime Electric, gives you peace of mind and can also increase the value of your home.
Many older homes in Toronto and the GTA still operate on outdated fuse boxes or 60 amp electrical services, while modern homes typically require at least 100 to 200 amps to safely support today’s electrical demands. An overloaded or outdated panel can become both a safety hazard and an inconvenience. After all, who wants the lights to go out every time they use the microwave?
Upgrading your electrical panel is a good idea, especially if your system is over 25 years old or your home’s electrical demands have increased over time. But here’s a closer look at electrical panel upgrade costs, courtesy of the experienced electricians at Ontime Electric.
Electrical Panel Replacement Costs
- Electrical panel replacement in Toronto and the GTA typically ranges from $2,000 to $5,000+, depending on amperage, wiring condition, permits, and labour.
- Wiring and rewiring costs vary depending on home size, accessibility, and the condition of the existing electrical system.
- Rewiring an entire home can cost Canadian homeowners approximately $4,000 to $12,000+.
- Replacing switches and outlets typically costs between $130 and $260 per device.
- Upgrading your electrical panel, rather than replacing the entire unit, generally ranges between $2,500 and $4,500.

Signs You Need to Replace or Upgrade Your Electrical Panel

You may need an electrical panel replacement or upgrade if:
You also need to determine what size electrical panel is suitable for your home. Electricians refer to this as “electrical load” to ensure your system safely supports your power needs. That’s why an in-home consultation with a professional electrician at Ontime Electric is important.

Electrical Panel Replacement Cost
The average cost to replace an old electrical panel with a new one of the same capacity in Toronto and the GTA typically ranges from $2,000 to $5,000+, depending on panel size, electrical demand, and other requirements. For example, a small bungalow will typically require less electrical capacity than a luxury home over 4,000 square feet.
Another factor to consider is updating older wiring, as a new electrical panel may not always be compatible with existing wires. Costs vary depending on home size, accessibility, and the condition of the existing electrical system. Rewiring an entire home can cost Canadian homeowners approximately $4,000 to $12,000+, depending on the scope of work required. For an accurate estimate, it is always best to consult a professional electrician.
Many homeowners also choose to replace outdated switches and outlets during the project for improved efficiency, capacity, and appearance. Professional replacement of switches and outlets typically costs between $130 and $260 per device.

Cost to Upgrade Electrical Panel to 200 Amps?

So what’s the cost to upgrade to a 200 amp service? A 200 amp electrical service is now the standard for most modern homes. If your panel capacity is below 200 amps, your electrical system may not safely support today’s power demands.
Upgrading from 100 to 200 amps typically costs between $2,500 and $4,500. If you are planning for future expansion or a larger property, a 400 amp panel can cost approximately $5,000 to $10,000+.
Material costs generally range from $400 to $1,000, while the remaining costs go toward permits, labour, inspections, and utility coordination. Electricians in the Greater Toronto Area typically charge between $90 and $150 per hour, while permits can range from approximately $65 to $385.
Fuse Box to Breaker Panel Conversion Cost

Until about the 1980s, fuse boxes were the standard electrical hubs in homes. Fuses need to be replaced every time they burn out and are becoming less common as modern breaker panels replace older systems.
If you need to convert a fuse box to a circuit breaker, you can expect to pay anywhere between $1,900 to $5,800, depending on panel size, amperage, and any required rewiring. During the replacement, your electrician may also need to coordinate a temporary power shutdown with the utility provider while the work takes place.
Cost to Replace a Single Breaker Switch or Fuse
If you are comfortable with basic DIY electrical work, replacing a fuse is usually straightforward. Fuses commonly cost between $6 and $50, while circuit breaker replacement typically ranges from $190 to $260.
So why are fuses so much cheaper? Replacing a fuse takes only seconds and is similar to changing a light bulb. Replacing a circuit breaker is a more advanced process that involves disconnecting and reconnecting wires before restoring power. If you are not comfortable handling electrical work yourself, it’s always best to contact a professional electrician, like the team at Ontime Electric.

Main Circuit Breaker Replacement Cost

The main circuit breaker is the switch usually located at the top of the electrical panel that controls power to the entire system. It plays an important role in both safety and renovations.
Despite its importance, replacing a main circuit breaker typically costs about the same as replacing a standard breaker, usually between $190 and $260.
