Although they have stated previously that you do not need to show proof of funds if you have a valid job offer or currently working in Canada under a valid work permit, you will have to show Proof of Means of Financial Support.
The help section reads:
If you are applying for permanent residence in Canada, you must provide an official letter issued by your financial institution indicating your financial profile.
Your financial profile includes a listing of all your bank (chequing and savings) and investment accounts. The official letter must be printed on the letterhead of the financial institution and must include your 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 balance of each account over the previous 6 months.
You must scan all proof of funds documents and save them as one file.
