Hi SDKD, not a part of this thread, silent observer but i must say you have a heart of gold. You, Drajpoot, Luder, Zakir and a whole of others. I was following up on the thread when i thought i will apply through Nova Scotia but eventually did not go that route because i got direct ITA.
Your file is in London because it is London VO that usually asks for Bio data page of passport. Please do not worry, this is usually the pre ppr mail that comes before PPR. Submit your documents immediately through your MyCIC account and send a mail to
LDNIMMIGRATION@international.gc.ca, to be sure that they have received it.
Congratulations ahead because your PPR is coming sooner than you think.
