I have one order that's lost out there in the system as far as I know, but the only thing from Canada that I have ever received after it was opened by the government was a big yellow envelope with 3 of Cannabis Culture back issues inside. No note, no explanation for why the top had been sliced open from one side to the other and it was left that way in the mailbox. Suckers didn't even bother to re-tape it so that everone down the line would know what they were handling.
For some reason though, small and discreet envelopes get here with regularity.
So if you are interested in buying then take your chances like the rest of us, but sooner than later I would think because the border is probably going to get tighter every year, and the risk will be greater.
