Performance matters and we always look for opportunities to improve. We make decisions with a sense of urgency and pivot to meet changing needs. We don’t shy away from hard work or difficult conversations.

We are one team. Together we win, grow and celebrate. We’re determined to be successful through inclusivity, trust and empowerment.


We operate in Canada, the United States and the Asia Pacific region, with operations in oil sands; conventional oil and natural gas; marketing, transportation, and refining.

Lima Refinery produces approximately two billion gallons of refined petroleum products annually, including jet fuel, diesel, and about 25 percent of Ohio’s gasoline supply.

The refinery has been in operation since 1886. On January 1, 2021 Cenovus Energy acquired Husky Energy and the refinery. The combined company is the second largest Canadian oil and natural gas producer and the second largest Canadian-based refiner and upgrader.
