Avert, Robinul, glycopyrrolate

Why is pharmacy.ca seem to be the only Canadian pharmacy selling glycopyrrolate without a prescription. Pharmacy.ca won't sell Avert to me because I put on my form that I was successfully being treated for high blood pressure. Is there any other source for glycopyrrolate in Canada? All the others I looked at say they require a valid US prescription. I know the potential dangers, I know the side effects. I just want the pills so I can see if they are the semi-miracle that they seem to be.
