The energy producer, majority-owned by Exxon Mobil, expects the restructuring to generate $150 million in annual savings by 2028. Calgary will bear the brunt of the cuts, with Imperial having operated its headquarters in the city since 2004. The company will take a one-time restructuring charge of roughly $330 million in the third quarter. Imperial runs major oilsands operations in northern Alberta at Kearl and Cold Lake and ranks as Canada’s largest petroleum refiner. TD Bank, Canada’s second-largest bank, announced a major restructuring in May that will eliminate approximately 2,000 positions.
