Shell Canada says it will close its largest Canadian refinery after a suitable buyer for the 76-year-old facility could not be found, leaving 500 direct employees and 2,500 indirect workers out of a job, according to AP. The petroleum giant said Friday that it will convert the refinery operations in Montreal, Quebec, to a distribution terminal. The refinery processes more than 130,000 barrels of crude oil daily. Shell Canada president Lorraine Mitchelmore says the company had interest from two potential buyers but Shell could not meet some of the terms put forward to realistically reach a sale agreement.
