Gra Ham Energy Limited

Gra Ham Energy Limited is one of the largest independent fuel suppliers in Ontario. We have been serving the home heat, farm, commercial and aviation markets for over 85 years by supplying, delivering and dispensing a full line of petroleum products.

Gra Ham Energy is located in St. Marys and serves all of Southwestern Ontario, with offices in the London-St. Marys-Kitchener corridor.

In Northern Ontario we own and operate bulk plants in Sudbury and Franktown, near Ottawa, for the distribution of aviation fuel, both jet and avgas.

Our recent venture into the drumming of aviation fuel has allowed us to ship to the mining industry in the far north.

We operate and supply several retail service stations and cardlocks in Southwestern Ontario. Look for the GOCO logo for fast, courteous service for the supply of premium, midgrade, and regular gasoline, clear and coloured diesel. We offer on time delivery and competitive pricing.

Our highly trained staff looks forward to serving you.
