UPDATE 7-Canada's biggest rail strike in a decade ends, backlogs could nag shippersMONTREAL/WINNIPEG, Nov 26 (Reuters) – Canada’s longest railroad strike in a decade ended on Tuesday as Canadian National Railway Co reached a tentative agreement with workers, but shippers warned it could take weeks before service bounces back to normal. News of the deal, which must still be ratified by union members, sent CN shares up by as much as 2%. Thousands of unionized workers began heading back to their jobs, CN said, with operations expected to be in full swing on Wednesday.
