Chances are if you order from Canada not likely. We have had major issues with so called "internet" pharmacies in my area selling prescription drugs to US customers. The catch is that if your US Dr. gives you a Rx for a drug, a "prescription broker" then forwards a fax of it to one of the internet pharmacies, who have licensed Dr's on their payrolls to "review" the prescription, and then countersign it making it a legal prescription in your name in Canada. The pharmacy then dispenses it, and ships it to your home by UPS,FEDEX,etc. they avoid the USMAIL however as the postal laws clearly prohibit the shipment of drugs through it.
This was a very popular way for US consumers to get access to cheaper Canadian pharmaceuticals a few years back, in fact a MN Senator even sponsored day bus trips to Canada for US Seniors to be able to get their meds this way, hoping to change legislation in the US regarding prescription drug costs and coverage.
With the CDN $ being pretty much at par with the US $ these days you don't hear about internet pharmacies much anymore, but I still pass one on my way into work each day. And the building is huge!!
