I also believe, as the CIC guidelines state, that any certificate issued AFTER you left the country is valid. However at the same time the letter above, is from the people directly involved in deciding my fate. As I stated in my original post, I'm taking the action I described on my own judgement, it is more than possible as the above letters are not widespread (only 2 I have read about have received these) it is possible it's one VO living in the past, or asked to deal with cases who does not normally, or hasn't for years, but asked to do so for streamlining. But who is using rules from a year ago etc.
I realize by posting the above I may have put some people into panic mode, but I would have felt irresponsible if I had read of the above letter, quietly submitted for my PCC, and said nothing.
Ironically, if someone was refused on the grounds described, I personally believe, as a layman, this would be grounds to appeal to the federal court, as IRCC are stating one thing then doing the total opposite. I would just rather avoid this situation altogether.
