It appears that the USPS and US Customs do not have the same rules for shipment of Optics to Canada. If you use PayPal or Click-n-Ship to create a paid label, part of the process is checking off a box confirming that you are not shipping and prohibited or restricted items as defined here: Canada But not so fast. I had a scope being shipped to Canada seized by our stalwart Homeland Security guys (US Customs) because they claim I needed an export license for it. After hours on the phone (all you get is "we're to busy to talk to you" recordings), I handed it off to my US Senator. Doubt I'll ever see the scope as it will probably be "sold" at some Customs Auction held at 2 AM on Christmas Eve. The meaning of those bumper stickers "I love my country, but fear my government" is getting more clear!
