Our history

We've been a leader in the energy industry since its beginnings. Our story began in 1880, when 16 refiners in southwestern Ontario created The Imperial Oil Company, Limited. 

Through our ongoing commitment to innovation, leadership and community, we now operate from coast to coast to coast.

We explore for, develop and produce the products that drive modern transportation, power cities, lubricate industries and provide petrochemical building blocks for thousands of consumer goods that people enjoy every day — including the familiar brands Esso and Mobil. 

We manufacture products operating the modern transportation, meeting the energy needs of cities, lubricant industry and providing basic petrochemical derivatives for thousands of consumer goods. For more information, use the scroll bar or down arrows to scroll through our history over time.
