The counter staff are amazing to deal with. Been coming here for years. The best supplier to deal with. They take care of you and are very genuine to deal with. Wish more supplier had the customer service these guys provide. Never disappointed as they have everything and there are minimal wait times. Very well organized and well stocked. Strongly recommended 👌

Michael B

We are an electrical contractor based in Guelph and were on a project in Toronto and no supplier around seemed to have stock of what we though was a pretty standard product - LED wall packs and bath fans! Not only did O'Neil Electric Supply have what we needed, we had several options to choose from.
