A few years ago DW and I went to Nova Scotia. We were in a car but we got THOROUGHLY searched. I got questioned as to why I had so many blood pressure pills. (since BP is daily, I often just take the entire bottle, esp when we don't have an exact return date). I tried explaining that to the nice customs officer who didn't seem to get it. Finally, I said look it's for blood pressure, it does not make you high, it makes you pee. There is no resale value. She finally OK'd it but told me next time to only carry the exact amount that I would need for the trip..... So, yes I am nervous about going to Canada.
