Nothing has changed except the amount as POF.Asivad Anac said:The long mail you added as evidence is from a Dec 2013 post on this forum (http://www.canadavisa.com/canada-immigration-discussion-board/proof-of-funds-real-estate-eg-house-apartment-land-t176271.15.html) from a member just like you and me. It does not constitute proof. And even if that mail came from CIC, things have changed since then.
Purpose
To confirm whether the applicant meets the low income cut-off (LICO), as assessed by amount of money they hold compared to the number of people in their family
Document requirements
The applicant should provide official letter(s) from financial institution(s) which list all current bank and investment accounts, as well as outstanding debts such as credit cards and loans. The letter(s) must be printed on the letterhead of the financial institution and must include applicant's name, the contact information of the financial institution (address, telephone number and e-mail address), the account numbers, dates of when each account was opened and the current balance of each account as well as the average balance in the past six months. Other documents may also be requested, as necessary.
Individuals who must submit this documentation
The principal applicant
Note that CIC doe not say anything here about cashable investments. Nor does it offer the choice of PA or the spouse being able to showcase this. It has to be the PA.
I don't make the rules or even interpret them. I just try to follow them and help others in trying to follow them. And the rules for POF under Express Entry are this. http://www.cic.gc.ca/english/resources/tools/perm/express/intake-complete.asp
I was confirmed; but you can not show anything regarding change of any rules.
You may mail to CIC to further clarification.
