Canada Post has officially resumed operations on Tuesday after a month-long strike by its employees.

Negotiations between the Canadian Union of Postal Workers (CUPW) and Canada Post did not go well, forcing the federal government to intervene.

Minister of Labour Steven MacKinnon called on the Canada Industrial Relations Board (CIRB) to assess whether the two parties could reach negotiated agreements by the end of 2024.

"After two days of hearings, the CIRB has issued its ruling confirming the parties are at an impasse," reads a statement from the postal service. "As a result, the CIRB has ordered employees to return to work and postal operations to resume at 8 a.m. local time on December 17, 2024."

MacKinnon said both parties are "unlikely to reach a deal by the end of the year."

In a statement on Monday, the crown corporation announced that it would begin ramping up and stabilizing operations across the country on Tuesday.

"With a large, integrated network of processing plants, depots and post offices, stabilizing operations will take time, and the company asks Canadians for their patience," reads the statement.

Now that Canada Post is back to work, here's everything you need to know about your mail.

Mail and parcels within Canada

The postal service says it will start working through the mail and parcels trapped in the system since the strike began on November 15 on a first-in, first-out basis.

It added that new commercial volumes will not be accepted into the network until Thursday, December 19.

"Service guarantees are suspended as the company ramps up operations," reads a statement.

Canada Post said Canadians should expect delivery delays through the remainder of 2024 and into January 2025. In addition, post office hours of operations may vary as the company works to stabilize operations.

International Canada Post mail and parcels

According to the postal service, it will work to process a significant accumulation of international mail and parcels currently queued up to enter the postal system.

"Customers should expect delays into 2025," reads a statement.

If you want to send a Christmas card overseas, it'll likely arrive in the new year as the postal system will only start accepting new international mail on December 23.
