1. What type of generator is best for a home in Toronto?

For most homeowners in Toronto and the GTA, a natural gas standby generator with an automatic transfer switch is the most convenient and reliable option. It activates automatically within 10 to 15 seconds of a power outage, runs on your home’s existing gas line with no fuel storage required, and shuts off automatically when utility power is restored. Portable generators with a properly installed transfer switch are a lower-cost alternative for homeowners who want essential circuit protection and do not require fully automatic operation.

2. Is a permit required for generator installation in Ontario?

Yes. Every generator connection to a home or commercial electrical panel in Ontario requires an ESA (Electrical Safety Authority) permit and inspection. Running a generator without a licensed transfer switch and a valid ESA permit is a violation of the Ontario Electrical Safety Code and can create serious safety risks for your family, your property, and utility workers. Daliran Electric pulls all required ESA permits and coordinates the inspection as part of every installation.

3. What is an automatic transfer switch and why do I need one?

An automatic transfer switch (ATS) is the device that connects your standby generator to your electrical panel and manages the switchover between utility power and generator power. When the transfer switch detects a power outage, it starts the generator and transfers your home’s electrical load to the generator automatically. When utility power is restored, it switches the load back and shuts the generator off. Without a proper transfer switch, connecting a generator to your home’s wiring creates a dangerous condition called backfeeding, which can injure or kill utility workers restoring power to your street.

4. What size generator do I need for my home?

Generator sizing depends on which loads you want to back up. A 9 kW to 13 kW generator covers essential circuits — furnace, sump pump, refrigerator, lighting, and internet. A 16 kW to 20 kW generator supports larger homes with central air conditioning and most major appliances. A 22 kW generator provides whole-home coverage for larger properties. We calculate your actual electrical load before recommending a size so your generator is correctly matched to your property’s requirements.

5. How often does a standby generator need maintenance?

Most standby generator manufacturers recommend annual maintenance, which typically includes an oil and filter change, spark plug inspection, battery check, coolant check, and a full system test. Standby generators perform a brief automatic self-test weekly, but a professional annual service ensures the unit will start and perform reliably during an actual outage. Daliran Electric can advise on maintenance requirements during your installation and connect you with generator service resources for long-term upkeep.

Expert Generator Installation: Safe, Reliable & Hassle-Free

Power outages across Toronto and the GTA are becoming more frequent and longer-lasting. Aging electrical infrastructure, severe winter ice storms, summer heat events, and high grid demand can knock out power for hours — or days — at a time. When that happens, your furnace, sump pump, refrigerator, medical equipment, security system, and home office can all go dark at the same moment.

A professionally installed backup generator solves that problem permanently. A standby generator senses a power failure within seconds, starts automatically, and restores power to your home or business before you even reach for a flashlight. When grid power returns, the generator shuts off and your electrical system switches back — all without any action required on your part.

Daliran Electric installs home standby generators, commercial backup generators, and portable generator transfer switches for residential properties, businesses, and new construction projects across Toronto and the Greater Toronto Area.

We handle the complete electrical side of every generator installation — load assessment, panel work, transfer switch installation, generator wiring, ESA permits, and final inspection — so your backup power system is ready to operate the moment it is needed.

Residential Generator Installation

For homeowners in Toronto and the GTA, a backup generator is one of the most valuable investments you can make in your home’s safety and resilience. A whole-home standby generator runs on natural gas or propane and activates automatically — meaning you stay protected even when you are away, asleep, or dealing with a medical situation at home.

Our residential generator installation services include:

Whole-home standby generator installation (natural gas and propane)
Essential circuit standby generator installation
Automatic transfer switch (ATS) installation
Manual transfer switch installation
Portable generator interlock kit installation
Generator wiring and dedicated circuit installation
Load calculation and generator sizing assessment
Electrical panel assessment and upgrades when required
Concrete pad coordination and generator placement
New home generator rough-in during construction
Annual generator maintenance and inspection
Generator troubleshooting and repair

We assess your home’s electrical panel, essential load requirements, available fuel source, and installation location before recommending the right generator size and transfer switch setup for your property.

Commercial Generator Installation

For businesses and commercial properties, a power outage is not just an inconvenience — it is a direct financial and operational risk. Lost data, spoiled inventory, halted production, closed registers, interrupted customer service, and potential liability can all follow from an unplanned outage that a properly installed commercial generator would have prevented entirely.

Daliran Electric installs commercial backup generators for:

Office buildings and professional practices
Retail stores and shopping centres
Restaurants and food service operations
Condo buildings and multi-unit residential properties
Warehouses and distribution facilities
Server rooms and data closets
Medical, dental, and healthcare offices
Hotels and hospitality facilities
Industrial and manufacturing facilities
New commercial construction projects

From a small essential-circuit generator for a single retail location to a large commercial standby system for a multi-storey building, we design and complete the electrical infrastructure based on your facility’s specific load requirements and backup priorities.

Standby Generator vs. Portable Generator — What Is the Difference?
Understanding the two main types of backup generators helps you choose the right solution for your property and budget.
Standby Generator (Home Standby / Whole-Home Generator)

A standby generator is a permanently installed unit that sits outside your home on a concrete pad, connected to your electrical panel through an automatic transfer switch and a dedicated natural gas or propane fuel line. When utility power fails, the transfer switch detects the outage and starts the generator automatically — typically within 10 to 15 seconds — without any manual action required.

Standby generators are available in sizes from 9 kW (essential circuits) up to 22 kW or larger for whole-home protection, and into the 60 kW to 150 kW range for commercial applications.

Standby generators are ideal for:

Homeowners who want fully automatic, hands-free backup power
Properties with medical equipment or sump pump dependency
Families who travel frequently or want protection when away from home
Businesses that cannot tolerate any interruption in power supply
Properties on natural gas service (no fuel storage required)
Portable Generator with Transfer Switch

A portable generator is a freestanding unit that is manually started and connected to your home’s electrical system through an interlock kit or manual transfer switch installed on your electrical panel. Portable generators run on gasoline, propane, or dual fuel, and must be operated outdoors due to carbon monoxide risk.

Portable generators with a properly installed transfer switch are ideal for:

Homeowners looking for a cost-effective backup power option
Properties where permanent installation is not practical
Essential circuit protection during occasional outages
Seasonal or recreational properties

In Ontario, connecting any generator to your home’s electrical panel requires a proper transfer mechanism — interlock kit, manual transfer switch, or automatic transfer switch — installed by a licensed electrician with an ESA permit. Running a generator without a transfer switch is illegal and dangerous.

Do You Need a Panel Upgrade for Generator Installation?

Some homes and businesses have enough electrical capacity to support a backup generator installation without changes. Others may require a panel upgrade, a load management solution, or a dedicated circuit before the generator and transfer switch can be installed safely.

Older homes with 100-amp panels may not have enough service capacity for a full whole-home standby generator alongside all existing electrical loads. Our electricians perform a load assessment before any installation begins and advise you clearly on what electrical work is required.

All generator wiring, transfer switches, and panel connections are completed to ESA standards and inspected to Ontario Electrical Safety Code requirements before the system is activated.

Generator Sizing — How Much Power Do You Need?

Choosing the right generator size is one of the most important decisions in the installation process. A generator that is too small will not support your essential loads. A generator that is oversized for your property wastes budget unnecessarily.

Our electricians calculate your actual electrical load before recommending a generator size. Common sizing benchmarks for Toronto and GTA homes:

9 kW to 13 kW — Essential circuits: furnace, sump pump, refrigerator, lighting, outlets, internet
16 kW to 20 kW — Larger homes with central air conditioning, electric stove, and multiple appliances
22 kW and above — Whole-home coverage for larger properties including EV chargers and all major appliances
60 kW to 150 kW+ — Commercial applications, office buildings, and multi-unit residential

We size every generator based on your actual panel load data, not estimates or averages, to ensure the installed system performs reliably when it is needed.

Our Generator Installation Process

1. Load Assessment and Site Evaluation

We review your electrical panel, calculate your essential and whole-home load requirements, assess the available fuel source (natural gas or propane), and evaluate the generator placement location — including clearance from windows, doors, and neighbouring properties in compliance with Ontario building and electrical codes.

2. Generator Sizing and Transfer Switch Selection

Based on the load assessment, we recommend the right generator size (in kW) and the appropriate transfer switch type — automatic transfer switch (ATS), manual transfer switch, or interlock kit — to match your backup power goals and budget.

3. Electrical Installation

Our licensed electricians install the dedicated wiring, transfer switch, and panel connections. We coordinate with your concrete contractor for pad preparation and with your gas fitter or utility for fuel line connection when required. ESA permits are pulled before any installation work begins.

4. Final Testing, Commissioning, and Inspection

We test the complete generator system — verifying automatic transfer switch operation, generator startup time, voltage output, and all electrical connections. The ESA inspection is arranged and coordinated as part of every installation. We walk you through the system controls and provide guidance on maintenance scheduling before the project is complete.
