After searching methodically on the one world site I found the oneworld_explorer_rule_sheet.pdf. Under the point #15 the exception that the oneworld representative referred to about Canada was there. I then called the BA people to debate and lo and behold the BA rep. had actually debated this same exception with his supervisors before. He has tried to speed up their response by pointing out this exception and hopefully I will be ticketed by this evening. Thank You flyertalk for this info. I hope this will help someone somewhere.
