Canada Customs has been working without a contract for some time now
and " may" be doing some "work to rule." I don't know this but it is
a fairly common tactic during labor/management negotiations.
Another story that was on one of Vancouver TV stations said that
due to security concerns the USPS was no longer directing parcels to
Calgary or Regina leaving Vancouver as the main point of entry in the
west. This resulted in a horrendous backlog of parcels waiting to
clear customs.
