About Us
Helping our customers Since 1945
Thompson Electric is a 3rd generation family owned business that has served the Belleville to Cornwall corridor of Eastern Ontario for over 70 years.
When Russell Thompson returned from serving over seas in WWII, he settled in the Seeley’s Bay area and soon established Thompson Electric as a one man electrical repair service.
Since then, we have grown through three generations of family ownership to become an established and recognized electrical contractor in the Kingston & 1000 Islands region.
