IMPERIAL OIL LTD. $41 (www.imperialoil.ca) gets roughly a third of its production from its 71%-owned Kearl oil sands project, 70 kilometres north of Fort McMurray, Alberta. ExxonMobil (New York symbol XOM) holds the remaining 29%; Exxon also owns 69.9% of Imperial. Because of the wildfires in Alberta, the company shut down Kearl. Now that the fires have subsided, the project has resumed normal operations. Best Buy.
