Why didn't anyone tell me? Postal workers in Canada started "rolling strikes" on 2 June; ten days later, Canada Post responded by lockin' 'em out. (The postal workers are citing safety and a scheme under which new hires get significantly less pay and benefits; this, IMO, is a Canadian issue on which my opinion is entirely irrelevant).
That seems to be the status quo to date; the Canadian Federal government has been making back-to-work sounds but doesn't look to have got anything far enough along to resolve matters. (See above).
--One source claims that pension and assistance cheques are being processed; but past that, it would seem not a wheel is turning in the vast nation's entire mail service. If you want to hear from great-aunt Tillie, it's the phone or the 'net. (Unless she's got an amateur radio license).
Labor issues aside (see "knot, Gordian"), this means one unexpected wonderful thing: an entire modern nation, our friendly neighbors to the North, have freed themselves from the scourge of junk mail!
Congratulatuions, Canadians. This is a painful step but some nation had to have the courage to go first.
