Hey Simpsonly, great questions and to the best of my knowledge I could only agree with uksausage, because I don't want to be providing you with only my assumptions and not logical reasonings. I do not know the exact reasons, but in my opinion, I would say the bars/standards are set differnely in each country. If I remember correctly, it only took Health Canada 14 days to approve BIEL's products in Canada. But for your peace of mind, in my opinion, you could try and research Health Canada to obtain BIEL's approval letters/documentations.
Hopefully other better informed investors regarding to this matter, like uksausage or imrich (who works in the clinical trials' field relating to the FDA), could provide answers to this question.
All in my opinion.
