The consulate makes a weekly mail run to NY, so we have a US address. - Aug 2020
Someone at the consulate makes a trip to the US post office once a week to pick up/drop off mail to US, but I also use Canada Post for letters and small packages. - Feb 2018
The U.S. Consulate has a mail run to the US two times a week, or you can just use the excellent Canada Post. Or when you cross border on shopping trip, mail it there. - Aug 2012
Via US mail through the consulate. I used Canada Post for local mail without incident. Tell friends and family shipping things from the US not to use UPS to Canada. On a $40 package, there was a $20 customs charge the one and only time I used them (did not happen with Canada Post). - Dec 2009
Don't mail things to Canada - you'll pay high duties upon acceptance. $150 for golf clubs, etc. - Sep 2009
The APO is actually a bi-weekly mailrun to Champlain, NY, so getting mail is very easy. - Jan 2009
