Canada have been having rolling strikes for the past few weeks and this is the latest - Canada has requested that countries stop sending their mail through.
This is from the Royal Mail website -
------
As a result of ongoing industrial action, we have now been requested to suspend the dispatching of international traffic destined for Canada, from today until further notice. Items posted yesterday and entering the network today will be held safely in our international distribution centre, awaiting further updates from Canada Post. This applies not only to us, but all International Postal Operators. Canada Post are aware of the impact to all customers and are therefore continuing to attempt to reach a settlement with the Canadian Union of Postal Workers (CUPW). We recommend you consider delaying sending items bound for Canada in the coming days as we expect this to remain the situation until we receive further guidance. However, if you still wish to send items bound for Canada, we are still accepting them and will continue to hold them at our international distribution centre.
Once we know the outcome of the latest negotiations, we will then either suspend our services to Canada, not accepting your items, or we will start to ease our backlog by forwarding items to Canada for distribution. The volume of backlogs currently being seen in Canada mean that it will take some time to clear these items, as overtime hours are being limited by CUPW representatives.

Fortunately I took Canada off my shipping destinations a few years ago and have never lost any sleep over it.
