Like any business, our employees are our most loyal customers.
We have 800 workers at our Sarnia site, and the Brand Starts Here - with all of them.
Imperial’s Sarnia operations include:
- Refinery: processes mainly Canadian crude oil to produce a range of petroleum products including gasoline, aviation fuel, diesel, home heating fuel and marine fuel; capacity is approximately 121,000 barrels of crude oil per day
- Chemical plant: The Sarnia chemical plant has access to feedstocks ranging from light gases to heavy liquids, including ethane from abundant supplies of North American shale energy. We produce a wide range of products used in the manufacture of many things that we use every day, for example: polyethylene, solvents, higher olefins (often used in lubricants) and aromatics (e.g., benzene used in making dyes or synthetic detergents, and polyurethanes and xylenes used to make plastics and synthetic fibers.)
- Research centre: a world-class facility focused on supporting customers, developing and improving petroleum products and providing new technologies to improve environmental performance
In all of our businesses, we make it a priority to engage with Indigenous and local communities on safety and environmental initiatives.

To responsibly meet the demand for energy we continuously look to improve technologies and practices that reduce our impact on the land, water and air. Read about our environmental performance in the current Corporate Citizenship Report
The Sarnia site has recorded a 69 percent reduction in sulphur-dioxide emissions since 2006. The elimination of coke burning and the operation of our tail-gas cleanup unit were contributing factors to our emissions reduction success. We have also reduced nitrogen-oxide emissions by 13 percent since 2009, thanks in part to increased use of our cogeneration plant, which burns cleaner fuel, and the elimination of coke burning.
Imperial has also reduced fugitive benzene emissions by about 90 percent since 1994 at our Sarnia site. Fugitive emissions are small air emissions that are inherent to any production process. We use infrared imaging devices to monitor the plant for emissions, and we’ve developed processes to repair leaks without shutting down the manufacturing process. As a result, this reduction was achieved despite overall higher production at the Sarnia site.
The Ontario government’s fenceline monitoring program benefits the public and helps the company by establishing a consistent way to monitor safe operations at our fenceline. Learn more about fenceline monitoring and view Imperial’s monitoring data at iolfencelinemonitoring.ca.
