I may be answering my own question here, but I'll ask anyway. With all the drama and busts going on in Canada recently people seem to either think that mail over there is under a microscope and being more closely inspected/monitored or that LE is full of shit and only going after suppliers. So what is the actual risk of ordering CAN->US right now?
There is so much trade happening between US and Canada that there shouldn't be an issue, as long as the vendor has good stealth.
Personally, I keep my orders domestic to avoid customs.
