I've used the online tools several times - it would print out the shipping label, and a customs document that I signed and included in the labelope with the shipping label. (for items leaving Canada, of course).
Today I used the desktop version for the first time - one item shipped within my province, and one going small packet to the U.S. For the Canadian item, it printed out the shipping label, and 3 manifests, and for the U.S. item it printed out the shipping label and 2 manifests. I didn't know what to do with everything (besides putting the label in the labelope) so I took everything to the post office with me. This was their first experience with a customer using the desktop tools, so they called someone to ask what to do - and what they ended up doing was have me sign 2 of the 3 Canadian manifests - then he initialed all 3, and gave me one to keep (the one I didn't sign). For the U.S. ones, he said there should be 3 (only 2 printed out) so he photocopied one, then did the same as was done with the Canadian ones.
So, was everything done correctly?
And, should there have been a customs document printed out like the online tools does, or no?
