Canada Post says customers should be prepared for possible service delays as it has received strike notice from the Canadian Union of Postal Workers, representing some 55-thousand members.

The strike would begin at midnight Friday, unless the parties reach agreements before then.

Canada Post says in the event CUPW initiates rotating strike activity, it intends to continue delivering in unaffected areas while working to reach agreements.

In the event of a national labour disruption, mail and parcels will not be delivered and no new items will be accepted until the disruption is over.

All mail and parcels in the network will be secured and delivered once operations resume.

Following either a rotating strike or a national labour disruption, processing and delivery may take some time to fully return to normal, as was the case after a month-long strike in the fall.

The Crown Corporation says it has recorded more than $3 billion in losses before tax since 2018, and it will post another significant loss for 2024.
