Hi Kevin,
The Canadian company is only a distributor of BioXtra. I forget where it's produced. I originally emailed the Canadian company,but after getting no response I ordered the mouthwash and paste via Amazon UK. Unfortunately, I can't use either because they contain Fragrance, which the Canadian company FAQ page does not list: http://www.bioxtra.ca/FAQ.html
Although this product is very odor neutral, the "fragrance" ingredient seems to be added for flavor as one if it's ingredients was a citrus flavor oil. I can't use any product containing flavor oils only. They are simply too strong for me and make my mouth burn. But my mouth is very sensitive and others might be able to tolerate what I can't. I know in a previous post a member in the UK said she purchased BioXtra paste (I believe), liked it and was using it.
Hope this info is useful to you. Know it's more than a month after you originally asked for feedback.
