Hi,
Is it really needed to maintain bank balance till the PR process is finalized? We,of course would not process to settle in developed country like Canada if we were able to maintain quality of life living in our own country. I think most of the applicants here belong to developing countries applying Canadian PR with the aim of getting sound salary to secure future for their family especially for their offspring. Who is willing to apply Canada if already have adequate fund in hand. So, I do not think we need to deposit and maintain that much huge balance in our account.
Even immigration officers are aware of it that's why they have designed criteria for POF that should be on the form of:
current bank certification letter
evidence of saving balance
fixed or time deposit amounts
Nowhere ,they have mentioned that amount must be deposited for specific period of time or should have past transaction history. They have just mentioned that one can not borrow money for the PR process since borrowed money cannot be in the hands of applicant if visa is issued to them and Canadian government has to bear the responsibilities for settling PR holders in Canada. What if you are able to manage money in the form of debt and you claimed that money is yours and even able to produce required money at the time of landing.
