Cheers Alan, I don't know anyone who tests North of the border,but I can recommend Gary Spavin and one that I have not used but my mate as,is the new Belgica De WeerdUK. lab.He gave it top marks,they phone you with the results followed by letter,advised on the phone your requirements which being registered(you) they can send out right away.Where as Gary can not prescribe POM but can advise.
