If your home’s electrical system struggles to keep up with modern demands—tripping breakers, flickering lights, or insufficient power for new appliances—you likely need an electrical service upgrade in Toronto. This comprehensive guide explains everything Ontario homeowners need to know about upgrading their electrical service in 2026.
What Is an Electrical Service Upgrade?
An electrical service upgrade involves increasing your home’s electrical capacity by replacing or upgrading key components of your electrical system. This typically includes:
- Upgrading your electrical panel (from 100 amps to 200 amps)
- Replacing outdated service entrance cables
- Installing a new meter base
- Upgrading the main service disconnect
- Updating wiring to meet current Ontario Electrical Safety Code standards
Many Toronto homes built before 1990 have 100-amp or even 60-amp service—insufficient for today’s electrical demands including central air conditioning, electric vehicle chargers, home automation systems, and multiple high-power appliances.
Signs You Need an Electrical Service Upgrade in Toronto
Our team of 30+ licensed electricians in the GTA regularly encounters these warning signs that indicate your Toronto home needs a service upgrade:
1. Frequent Circuit Breaker Trips
If your breakers trip regularly when running multiple appliances, your electrical system is overloaded. This isn’t just inconvenient—it’s a fire hazard.
2. Flickering or Dimming Lights
Lights that dim when you turn on major appliances indicate your electrical service can’t handle the load. This is especially common in older North York and Toronto homes.
3. Planning Major Renovations
Kitchen remodels, basement finishing, or home additions typically require additional electrical capacity. Building permits in Ontario often mandate service upgrades for significant renovations.
4. Installing an EV Charger
Level 2 EV charger installation in Toronto requires substantial power (typically 40-50 amps). Most homes with 100-amp service need an upgrade to safely accommodate an EV charger alongside existing electrical demands.
5. You Have a Fuse Box Instead of Circuit Breakers
If your home still uses fuses rather than circuit breakers, your electrical system is outdated and doesn’t meet current Ontario Electrical Safety Code requirements. An upgrade is essential for safety and functionality.
6. Buying or Selling a Home
Home inspections in Toronto frequently identify outdated electrical systems. Upgrading before listing can increase your home’s value and appeal to buyers in competitive GTA markets like Vaughan, Markham, and Richmond Hill.
The Electrical Service Upgrade Process in Toronto
Understanding the process helps you prepare for your upgrade. Here’s what to expect when working with a certified electrician in Toronto:
Step 1: Professional Assessment
A licensed electrician evaluates your current electrical system, discusses your power needs, and recommends the appropriate service size (typically 200 amps for modern homes). At North York Electricians, we provide free estimates—call +1 (647) 832-3800 to schedule yours.
Step 2: Obtain Electrical Permit
All electrical service upgrades in Ontario require a permit from the Electrical Safety Authority (ESA). Your electrician typically handles permit applications, ensuring compliance with the Ontario Electrical Safety Code.
Step 3: Coordination with Toronto Hydro
Your electrician coordinates with Toronto Hydro or your local utility provider to disconnect and reconnect power. This typically involves a brief power outage (2-6 hours).
Step 4: Installation
The upgrade process includes:
- Installing the new electrical panel
- Upgrading service entrance cables
- Replacing the meter base
- Reconnecting all circuits
- Testing the entire system
Step 5: ESA Inspection
An Electrical Safety Authority inspector verifies the work meets Ontario safety standards. Once approved, Toronto Hydro reconnects permanent power.
Most residential electrical service upgrades in North York and Toronto take 1-2 days to complete, depending on complexity.
How Much Does an Electrical Service Upgrade Cost in Toronto?
The cost varies based on several factors:
- Service size: 200-amp upgrades are most common for residential properties
- Panel location: Exterior vs. interior installation affects labour costs
- Service entrance length: Distance from the street to your panel impacts material costs
- Additional work: Rewiring, grounding upgrades, or meter base relocation add to costs
In 2026, Toronto homeowners typically invest $2,500 to $5,000 for a complete 200-amp service upgrade, including:
- Labour from licensed electricians
- All materials and equipment
- Electrical permits and ESA inspection fees
- Coordination with Toronto Hydro
Complex upgrades or homes requiring extensive rewiring may cost more. Get an accurate quote by contacting our team of experienced electricians at +1 (647) 832-3800.

Clear the area: Ensure easy access to your electrical panel and meter by removing obstacles before your electrician arrives.
Consider bundling work: If you need rewiring services in Toronto, switches and outlets repair, or home automation installation, completing these projects during your service upgrade can save time and money.

Frequently Asked Questions
How long does an electrical service upgrade take in Toronto?
Most residential service upgrades take 1-2 days. This includes installation time and coordination with Toronto Hydro. Complex projects requiring extensive rewiring may take longer. Your electrician provides a detailed timeline during the estimate.
Do I need a permit for an electrical service upgrade in Ontario?

Licensed electricians typically handle permit applications and ensure work complies with the Ontario Electrical Safety Code.

Can I upgrade my electrical panel without upgrading the service entrance?
Not usually. If you’re increasing your service capacity (e.g., from 100 to 200 amps), the service entrance cables must also be upgraded to safely handle the increased load. A licensed electrician in Toronto evaluates your entire system and recommends necessary upgrades.
Will my power be off during the entire upgrade?
Your power will be disconnected during the installation, typically for 2-6 hours. Your electrician coordinates with Toronto Hydro to minimize disruption. Plan accordingly by charging devices, having alternative cooking arrangements, and considering temperature control needs.
Is a 200-amp service enough for an EV charger in Toronto?
Yes, a 200-amp service provides sufficient capacity for a Level 2 EV charger plus typical household electrical loads. If you plan to install multiple EV chargers or have exceptionally high electrical demands, discuss your specific needs with a certified electrician.
