Teamsters Canada says its members at Purolator will not handle packages postmarked or originating from Canada Post amid an ongoing strike by the Crown corporation's workers.

Canada Post has shut down across the country because tens of thousands of postal workers are on strike over wages, working conditions and other issues. The closure will affect millions of Canadians and businesses nationwide before the busy holiday season.

There are numerous options actually. Canada Post and the union representing its postal workers are negotiating a new collective agreement. While neither side has issued a notice of strike or lockout, both parties are in a legal position to do so. They must provide a minimum of 72 hours' notice before a labour disruption can occur.
