Residential and Commercial Electrical Service Upgrades in Toronto

Upgrade Your Electrical Service for Today’s Demands
100 Amp to 200Amp or More

Your electrical service is the power connection between your property and the utility. When that service is undersized or outdated, it limits what your home or business can safely run. We upgrade 100 amp and 125 amp services to 200 amps or more, giving you the capacity needed for EV chargers, heat pumps, electric water heaters, and modern appliances.

At Symmetric Electric Ltd., we provide full service upgrades across Toronto and the GTA. Every upgrade includes permits, coordination with your hydro utility, and a certified ESA inspection for complete peace of mind.

When Do You Need a Service Upgrade?

If your power supply can’t keep up with your home or business, it’s time to think about a service upgrade. Older 60 amp or 100 amp services were never designed for modern living, where EV chargers, heat pumps, and electric water heaters can easily push the limits of what your system can safely handle.

Common signs you may need a full service upgrade:

Main breaker trips when multiple large appliances run at once
Lights dim when high-power equipment starts
Old or corroded meter base or service mast
Utility disconnects or issues a Customer Action Form (CAF) notice
Plans to add EV chargers, heat pumps, or other major electrical loads

Upgrading your service increases total capacity from the utility, improves grounding and bonding, and ensures your system meets today’s safety and insurance requirements.

We handle the entire process from load calculations and utility coordination to ESA permits and final inspection, so you can power your property safely and confidently for years to come.

Service Upgrade Options and Equipment

We upgrade and replace every part of your electrical service, from the meter base to the main disconnect. Whether your system is overhead or underground, residential or commercial, we make sure it meets Ontario Electrical Code standards and your utility’s requirements.

Replacing 60 amp, 100 amp, or 125 amp services with new 200 amp equipment
Upgrading meter bases, service masts, and grounding systems
Coordinating disconnects and reconnections with your hydro utility
Converting from overhead to underground service feeds
Installing new 200 amp panels with modern breakers and labeling
Securing ESA permits, inspections, and all required documentation

Every installation is done to Ontario Electrical Code standards and inspected by the ESA for your safety and peace of mind.

What's Involved in a Service Upgrade

A service upgrade involves more than just replacing a panel. It is a coordinated process that ensures your entire electrical system, from the utility connection to the panel, is safe, sized correctly, and built to code.

Site Visit & Assement

We inspect your existing setup, calculate your total load, and confirm the right service size for your needs.

Planning & Permits

We handle all permits and paperwork with the Electrical Safety Authority (ESA) and coordinate with your hydro utility for disconnection and reconnection.

Professional Installation

We replace or upgrade your service mast, meter base, grounding system, and main disconnect, then install your new 200 amp panel. All wiring is labeled and torqued to specification.

Testing, Inspection & Cleanup

We meet the ESA inspector on-site, complete testing, and provide your official ESA Certificate of Inspection for your records and insurance provider. Once the job is approved, we tidy up the area, walk you through your new setup, and make sure everything is operating safely and efficiently.

Customer Action Forms (CAF) from Toronto Hydro
Or Safety Notices from Other Utilities

If you have received a Customer Action Form (CAF) from Toronto Hydro, it means your electrical equipment has been flagged as unsafe or outdated. This notice is usually issued when crews find an issue with customer-owned equipment such as a damaged meter base, rusted service mast, or unsafe connection point.

Other utilities in Ontario may use different names for the same type of notice:

Hydro One may issue a written request or warning under their Customer Equipment Repair Requirements section of their Conditions of Service.
Alectra Utilities (including former Enersource customers) may issue a Defective Customer Equipment Notice or similar warning requiring repairs before reconnection.

No matter what the notice is called, the meaning is the same — your equipment needs repair or replacement before power can continue safely.

We specialize in correcting CAFs and similar utility notices quickly and professionally. Our team handles everything from site inspection and quoting to ESA permits, coordination with your hydro utility, and final inspection. Once the work is complete, your system will meet current standards and your notice will be officially cleared.

If you have received any kind of safety or deficiency notice from your utility, contact us right away. We will inspect your system and take care of everything needed to bring it up to code.

Frequently Asked Questions About Panel Installations

What is included in a 200 amp service upgrade?

A 200 amp service upgrade includes replacing your existing meter base, service mast or conduit, grounding system, and main disconnect. We install a new 200 amp panel with modern breakers and labels, coordinate with your hydro utility for temporary disconnection and reconnection, and handle all permits and inspections through the Electrical Safety Authority (ESA). The result is a safe, modern electrical service ready for higher loads such as EV chargers, heat pumps, and electric water heaters.

How long does a service upgrade take?

Most service upgrades are completed in a single day. Larger or more complex projects, such as underground services or multi-unit buildings, may take longer due to coordination with the hydro utility and ESA inspection scheduling. We plan ahead to minimize downtime and restore your power as quickly and safely as possible.

Do I need to contact Toronto Hydro or will you handle it?

You don’t need to contact Toronto Hydro or any other utility directly. We take care of all coordination and communication for your service upgrade. That includes scheduling the temporary disconnection and reconnection, submitting the required documents, and ensuring the ESA inspection is completed. Our goal is to make the entire process smooth and stress-free for you.

What is a Customer Action Form (CAF)?

A Customer Action Form (CAF) is a notice issued by Toronto Hydro when they identify unsafe or outdated customer-owned electrical equipment such as a damaged meter base, rusted service mast, or loose connections. It means repairs or upgrades are required before the utility can continue safe service. We specialize in correcting CAF issues quickly and can coordinate all required ESA permits and inspections.

Can you fix issues noted on a CAF or utility notice?

Yes. We regularly handle repairs and upgrades related to Customer Action Forms (CAFs) and other utility deficiency notices. Our licensed electricians will inspect the issue, provide a clear quote, handle permits, and work directly with Toronto Hydro, Hydro One, or Alectra Utilities to restore compliance quickly. Once the work is complete, we ensure the ESA inspection passes and your service is fully approved.

What is the difference between overhead and underground service?

An overhead service brings power to your home through wires connected to a mast on your roof or wall, while an underground service runs power through cables buried in the ground. Both options deliver the same electricity, but underground systems are more protected from weather and can look cleaner. We handle both types, including trenching, conduit, and coordination with your hydro utility.

How much does a 200 amp service upgrade cost?

Costs vary depending on your setup, location, and whether the service is overhead or underground. A typical residential 200 amp service upgrade in Toronto starts around $3,000 to $4,500, including permits and inspection. Larger or more complex systems, especially commercial or multi-unit buildings, may cost more. We always provide a clear, itemized quote before starting any work.

Do I need an ESA permit for a service upgrade?

Yes. Every service upgrade in Ontario requires an ESA permit and inspection. We handle the entire process for you, including filing the permit, meeting the ESA inspector on-site, and providing your Certificate of Inspection once the work is approved. This ensures your system meets all safety and insurance requirements.

Will upgrading my service improve safety or insurance approval?

Yes. A new 200 amp service improves safety by eliminating old, corroded, or undersized equipment and providing proper grounding and bonding. Many insurance providers also prefer or require upgraded electrical systems to reduce fire and shock risk. Once completed, you’ll have an ESA Certificate of Inspection to share with your insurer or property manager.

Can you upgrade commercial or multi-unit services too?

Yes. We provide electrical service upgrades for both residential and commercial properties, including multi-unit buildings and small businesses. We size feeders and disconnects correctly, coordinate with the hydro utility for shutdowns, and ensure compliance with the Ontario Electrical Code for higher load systems. Every project includes an ESA inspection and a detailed completion certificate.
