Canada Post and the Canadian Union of Postal Workers (CUPW) have agreed to resume negotiations, and if those talks aren’t productive, a postal strike will pick up where it left off last December.

According to CanadaPost.ca, the two parties will work with the support of a mediator.

According to a news release on the website, negotiations are resuming after discussions broke off in March when the parties had been unable to come to a resolution. In 2024, Canada Post employees were on strike between Nov. 15 and Dec. 17.

The existing collective agreements between Canada Post and CUPW will continue to remain in effect until 11:59 p.m., May 22, 2025. After that time, strike action may occur.

“We will make every effort to be transparent and let you know if there is a risk of a labour disruption,” says the website. “Your business is important to us, and we value the trust you put in us to deliver day in and day out.”

During the last strike, the Uxbridge Cosmos was hand delivered to several locations around the township, including several municipal buildings, local shops, and planned pick-up spots.

Watch next week’s Cosmos for a full listing of all the locations at which the newspaper will be available. Or, sign up for the e-edition to be delivered directly via email. Visit

UPDATE: After Cosmos press time on May 13, 2025, Canada Post released the following on its website:

Negotiations paused to reset discussions and focus on resolution

After several days of discussions without meaningful progress, Canada Post has informed the Canadian Union of Postal Workers (CUPW) that a temporary pause in discussions is necessary. This pause will allow Canada Post to focus on preparing comprehensive proposals aimed at moving discussions forward constructively.

Negotiations resumed at the end of April after breaking off in March. While CUPW requested that both parties return to the table with the assistance of a mediator, the union has either held or hardened its previous positions on key issues, leaving little room for progress.

With collective agreements for CUPW-represented employees extended until May 22, 2025, we understand that our employees and the people we serve are counting on both parties to find a resolution and avoid further labour disruption. Canada Post has therefore advised CUPW that it will use this pause to prepare proposals designed to help advance negotiations and achieve a much-needed resolution. Any offers we bring forward will reflect the Corporation’s current realities.
