OTTAWA—  Postal Workers have gone on a nationwide strike in response to proposed operational changes by the federal government, marking a repeat of last year’s strike. Canada Post is projected to lose $1.5 billion by the end of the year, currently losing $10 million daily. Government-proposed changes  include shifting to ground delivery for non-priority mail, consolidating mailboxes and closing rural post offices. Union argues these changes lack clarity and could lead to significant job losses and reduced service. Canada Post is delivering just 2 billion letters each year, down from 5.5 billion in 2005, even as the number of homes has grown. Parcel volumes have also plunged, as Canada Post deals with high fixed costs. The Government says Canada Post is effectively insolvent, and repeated bailouts are not a long-term solution. Transformation is required to ensure the survival of Canada Post and protect the services Canadians.
