Thank you for your reply. 2 of my friends who are not in my startup group have just get their wp a couple of weeks ago and it has been issued for one year and began from the pass request date! It was odd and disappointing. I don’t know it is going to be the new policy or just the officer decision.For me, the validity of the original WP was 1 year. They now give it for 2 years I've heard (my Co-founder got it for 2 years - he applied for it a year after me) It is issued on the day you land, so validity is 1 year or 2 years from the day you land in Canada.
Documents for WP extension is essentially the same as the original WP - along with the addition of a "Business progress report" . It is as complicated,except of course no biometrics or medical is required.
Hope this helps!
you said the documents of the extension are the same to the original. I remember some documents for the wp like LOS, police check, fund and ielts that we submit for the wp, were not even in the checklist of the wp application but were in the instruction. Did you also submit these again?
