Electrical Panel Upgrade

Overview

An electrical panel upgrade is often necessary in Canadian homes built before the 1990s, many of which still have 60- or 100-amp service. Modern households draw far more power than older homes were designed for — electric vehicle chargers, heat pumps, home offices, and high-draw kitchen appliances all place demands that outdated panels cannot safely meet.

The most common upgrade is from 100-amp to 200-amp service, which provides enough capacity for a fully modern home. This involves replacing the main breaker panel, updating the meter base, and often running a new service cable from the utility connection. Some older homes with fuse boxes or Federal Pacific or Zinsco panels (known safety hazards) should be upgraded regardless of capacity needs.

An electrical panel upgrade must be performed by a licensed electrician and requires a permit and inspection in every Canadian province. The local utility company must disconnect and reconnect the service, which adds a coordination step to the project timeline.

What to Expect

• Licensed electrician inspects the existing panel and electrical system
• Load calculation to determine the appropriate service size
• Electrical permit application with the local authority
• Coordination with the utility company for service disconnect
• Removal of the old panel and any obsolete wiring
• Installation of the new panel, main breaker, and branch circuit breakers
• Grounding and bonding to current code standards
• Inspection by the Electrical Safety Authority (ESA) in Ontario or provincial equivalent
• Utility reconnection and final testing
• Timeline of 1 to 2 days for the installation, plus scheduling lead time

Cost Factors

The upgrade path (60A to 200A costs more than 100A to 200A) is the main cost driver. If the service entrance cable from the street needs replacement, costs increase. Adding new circuits during the upgrade (for an EV charger, workshop, or kitchen) is efficient and adds incremental cost. Panel location matters — moving a panel from one wall to another adds wiring and labour. In some provinces, the utility charges a fee for the service upgrade at the meter.

How to Save Money

• Combine the panel upgrade with other electrical work (new circuits, outlets, lighting) to avoid paying for a second visit
• Get three quotes from licensed electricians and compare the scope of work carefully
• Check for provincial rebate programs linked to EV charger or heat pump installations, which sometimes cover panel upgrade costs
• Avoid moving the panel location unless absolutely necessary
• Schedule during slower months (late fall or winter) when electricians may have more availability

Hiring Tips

• Only hire a licensed electrician (verify their licence with your provincial regulatory body)
• Confirm the electrician will handle the permit application, inspection scheduling, and utility coordination
• Ask about the warranty on workmanship (typically 1 to 2 years) in addition to the equipment warranty
• Ensure the quote includes all components: panel, breakers, service cable, grounding, and permit fees
• Check reviews and ask neighbours for recommendations — electricians with local experience know utility requirements in your area

FAQ

How do I know if I need a panel upgrade?

Common signs include frequently tripping breakers, a fuse box instead of a breaker panel, buzzing or warm panels, reliance on power bars and extension cords, or plans to add major loads like an EV charger or heat pump. A licensed electrician can assess your current capacity.

How long does a panel upgrade take?

The actual installation typically takes one full day. However, the total process from initial assessment to final utility reconnection can take 2 to 4 weeks, primarily due to permit processing and utility scheduling.

Is a 200-amp panel enough for a home with an EV charger?

For most Canadian homes, 200-amp service is sufficient even with an EV charger (which typically draws 40 amps). However, if you are also planning a heat pump, electric water heater, and a workshop, discuss load management options with your electrician. Some homes may benefit from a load management panel that prioritizes circuits.
