Just got this in my eBay inbox:
As you are likely aware, there is a possibility that Canada Post services will be impacted by a labour disruption as early as July 2, 2016. We encourage you to visit canadapost.ca/update
to read about the latest developments and sign up for email updates.
In the event of a Canada Post labour disruption, eBay will remain open for business, and we’re asking you to do the same. There is no need to put your store on vacation hold, to end listings, or to zero out quantities on multi-quantity listings.
Should Canada Post service be disrupted, we recommend that sellers:
Continue to list and sell on eBay; and
Be considerate and accommodate buyers who may wish to cancel orders if they have not yet been shipped.
eBay will be monitoring, and where possible adjusting, estimated delivery dates and eBay Money Back Guarantee timelines to ensure that sellers are not penalized for shipping delays.
eBay will communicate with buyers who purchase Canadian items prior to, or during, a labour disruption to ensure they are aware of the likelihood of shipping delays.
The eBay Canada Team will post additional details on the Announcements Board as they become available.
