Canada Post and the Canadian Union of Postal Workers remain at loggerheads in their negotiations for a new contract, with the deadline fast approaching for a possible strike or lockout. A work stoppage would affect 40,000 employees, while also freezing the delivery of paper mail and parcels.

Canadian businesses and municipalities are advising their customers to get their bill payments in the mail soon, ahead of a possible Canada Post service disruption on July 2.

Several cities have already issued advisories to residents over the potential disruption, advising them to get their property tax cheques in the mail before it's too late. Many are planning drop-off points in lieu of mail delivery.

Businesses are also preparing for the potential work stoppage, as customers flood them with questions about what will happen to their packages after July 2.

On Sunday, the union put out a list of 24 negotiating points that Canada Post has not included in its latest offer. The list includes calls for a wage increase above inflation, a prohibition against contracting out work, restoration of sick leave and the return of door-to-door delivery in all places where it was removed.
