Rotating strikes have taken their toll on the Canada Post over the past few weeks, with the Toronto mail processing center being hit for the second time in three weeks. The Toronto mail processing center is the largest mail center in Canada, and currently has 4,500 of its workers out on the picket lines. The union continues to shut down major processing centers, which is having a severe impact on mail deliveries. The three processing centers that are closed currently process close to a million parcels per day, so the strikes have created a considerable backlog of parcels that need to be processed. The strikes come as a result of the failure of the union and management to reach a new agreement, following 10 months of negotiations.
