Hiring trusted electrical contractors is essential for safe, code-compliant work in both homes and commercial properties. Ontario’s electrical regulations are strict, and only licensed contractors can file permits, perform compliant installations, and coordinate inspections with the Electrical Safety Authority (ESA).
As electrical systems become more complex—especially with EV chargers, hot tubs, and renovation upgrades—verifying credentials helps property owners avoid unsafe workmanship and unexpected costs. A straightforward verification process while working with an electrical contractor in Mississauga ensures every project begins on a strong, compliant foundation.
Difference Between an Electrician and an Electrical Contractor
Many property owners are unaware that “electrician” and “electrical contractor” are not the same in Ontario.
Electrician (Individual)
A certified tradesperson
Can perform electrical work
Cannot pull permits independently
Must work under a licensed electrical contractor
Electrical Contractor (Business)
Holds an ECRA/ESA license
Authorized to file permits
Required to maintain insurance and meet safety rules
Responsible for the work completed under their company
When searching for commercial electricians in Mississauga or residential professionals, the company—not the individual—must hold a valid ESA contractor license.
How to Check ESA Certification and Licensing Online
The Electrical Safety Authority provides an easy way to verify credentials:
Visit the ESA’s “Find a Licensed Electrical Contractor” page.
Enter the company name, location, or license number.
Confirm that the contractor is listed as active and in good standing.
Check for the ECRA/ESA license number on the contractor’s website or quote.
This verification protects property owners from unlicensed operators who cannot legally perform electrical work. It applies to all providers, including any electrical company in Mississauga offering residential or commercial services.
What Insurance and Warranties Should Be in Place
Licensed contractors must carry:
General liability insurance
WSIB coverage for workers
Valid ECRA/ESA contractor licensing
In addition, reputable contractors provide:
Written warranties for workmanship
Documentation for ESA inspections
Certificates of Acceptance for completed work
These protections ensure accountability and long-term safety.
Questions to Ask During a Consultation or Quote
When meeting with electrical contractors, ask:
What is your ECRA/ESA license number?
Will an ESA permit be filed for this work?
Are your workers covered by WSIB?
What warranties do you provide for residential or commercial projects?
How long have you served clients in Mississauga?
Who will perform the work—employees or subcontractors?
Clear answers indicate a qualified professional, whether hiring commercial electricians in Mississauga or someone for home repairs.
Common Red Flags That Indicate Poor Quality or Noncompliance
Avoid contractors who:
Do not provide an ECRA/ESA license number
Suggest completing work without a permit
Offer unusually low pricing with no explanation
Have no written estimates or warranties
Ask for full payment before work begins
Avoid answering questions about insurance
These warning signs often indicate unlicensed or non-compliant operators.

I called Young for a small job after using his company Canadian Wire Wizards previously about a year ago. Once again I was not disappointed. Young came himself on time, and quickly assessed the issue, and offered good advice on the optical placement of a new electrical receptacle for a basement dehumidifier. The work was completed in a professional, timely, and efficient manner that you would expect from a master electrician. We have lived in our century year old Toronto home for over 40 years and have had the occasion to hire many tradesmen over that period. Young and his team from Canadian Wire Wizards stands out among the best in helping us live safely while preserving our investment!

As a first time homeowner moving into an older Toronto house, there were a lot of daunting/new challenges; one being knob and tube. Demetri was very professional and reliable. We had called a few places to get some quotes (some of which didn't even show up or showed up very late). Demetri and his team was a pro from start to finish. Would definitely use them again and recommend them to everyone!

Young and the team helped me troubleshoot issues with our breakers. Over the phone, they were incredibly enthusiastic and actually sounded like they were having fun helping people out.
These are the type of people I love to support. Friendly, honest, helpful service. Would highly recommend them!

Excellent team of electricians. Installed a small panel in my shed and left the place cleaner than before they started.
They even gave me some tips, like dimmer switch should not be used with motion sensor light, which I did not know.
Fair price and excellent service, highly recommended!

We hired Canadian Wire Wizards to install new 15amp GFCI type
receptacles in our home and garage as well as to repair our exterior back light and switch.
Overall, Demetri and his team of technicians (Jason and Sean) were great and I highly recommend Canadian Wire Wizards. They are very professional, friendly, efficient and customer-oriented. We asked 3 different vendors for their quotes and Canadian Wire Wizards team was the most reasonable and diligent one from start to finish. Demetri first came to our home to assess our needs in person and came back to us with very reasonable and thoughtful estimate. Jason and Sean completed their installation and repair work in a timely manner and left our place clean.
Due to their outstanding service, I intend to use Canadian Wire Wizards for any future needs.

We just bought our first house and we were VERY Nervous when we found out there was Knob and Tube in it. Our realtor suggested Young and his crew and we couldn't be happier! Young did a full survey of the house and let us know what would be needed to update the wiring to code, there wasn't any pressure or crazy upsells, he listened to what we need and just provided some great suggestions on placement to make our lives easier! We had a bit of a rushed timeline and he was able to get started right away. He kept us updated on the process, always calling or texting if he had any questions or concerns before he placed an outlet or switch.
We couldn't of asked for a better experience and we have found our electrical team for life!
Electrical stuff can be scary but not with this team! make sure you call them ASAP.

I engaged this company to make many electrical improvements to my home in Etobicoke. From the estimate to the invoice payment receipt, all went well. The electricians were prompt, polite, professional, accommodating to changes and educational, Young in particular. Highly recommended.
