Panel Upgrade/EV Charger
Yarik upgraded our home electrical panel to 200A and installed a NEMA 14-50 outlet in our garage for EV charging. I asked him many questions about the cable type he was going to use. He responded with great patience without getting annoyed. I finally accepted his cable recommendation, which he backed up with technical details. Thanks to this, I can upgrade my charger at a later date without changing the cable.
Yarik handled all communications, permission, certification etc. and was punctual and efficient. He also made some minor changes I requested without complaining. I have a finished basement, and routing the cable from the basement to the garage was a bit tricky, but he managed to do this with minimal damage. He covered work areas with cloth to protect from dirt and cleaned up everything after work.
Yarik and his associate are well trained and the quality of their work is excellent. See how neatly the panel cables are arranged. They were in a messy bunch before. Look no further if you want to do a panel upgrade or an EV charging installation.

I’ve had the pleasure of working with Yaroslav from ON Energy on several occasions, and I can’t recommend him highly enough. Yaroslav is an absolute professional — he handled multiple upgrades around my house with exceptional skill and attention to detail. Not only did he complete each project efficiently, but he also took the time to explain his work and offer helpful advice for future maintenance. It’s clear he has extensive knowledge and pride in his work, which made a real difference in the quality and safety of the upgrades. If you’re looking for a trustworthy, skilled electrician, ON Energy and Yaroslav are the team to call!

EV Charger/Panel Upgrade
Yaroslav is truly a pro & was a pleasure to deal with. He offered a competitive rate to upgrade the panel to 200AMP + install a Tesla wall charger. Arrived when promised, communicated well, and job well done. Highly recommended.

Electrical Panel Upgrade
Great electrician! Hired him to do panel replacement, he picked up the parts, contacted Toronto Hydro (for power shutdown and startup) and contacted ESA to come by and inspect. Wonderful service from start to finish! Do recommend!

Electrical Panel Upgrade
I hired Yaroslav to upgrade my main panel to 200A. He answered all of my questions along the way, maintained excellent communication from start to finish, completed everything he said he would do on the job-site, and went above and beyond to help me out with installing a new insulated plywood backing for the new panel to mount to. No complaints whatsoever. Thank you!

EV Charger Installation
Absolutely amazing service and professional installation. From the moment Yaroslav from ON Energy arrived to the time he left, he ensured a clean, efficient, and professional service. He took the time and care to answer questions I had, kept the work area clean/cleaned up any debris, and accommodated any and all requests I had.
I would highly recommend him for EV charger installs and based on what I experienced any other electrical service he has to offer. 10/10 on install, cleanup, professionalism, quality, attention to detail.

A high quality job done nicely. I would highly recommend Yarik to anyone!!! Very happy to come across Yarik for this job.

EV Charger Installation
Yaroslav did a superb job hooking up our EV charger and was recommended to me by a friend. Pricing was good. He also did other electrical work through our whole home to meet Electrical Safety Authority's inspection ( which wasn't finished by the previous owner who sold us the home). Clean up was amazing as he brought his own portable vacuum. Very well mannered: knocking on doors I had closed before entering. Also making sure I understood what he had to do. Very clear and concise quote and detail of work to be done on each floor. Before I decided to have him take on the permit for the Electrical Safety Authority, the inspector asked who I was hiring and made sure for me that Yaroslav was in excellent standing. He was understanding and tried to be as flexible with me needing to pick up and drop off my kids to school. Highly recommend his work.

Yarrik has done two jobs for me and a few for my friends. He does a great job and is very reasonable. There are some greedy contractors who are always screaming "extra, extra" once they start the job and you can't replace them. Yarrik never does that. He is a great guy. I recommend him very highly.
