don't need national ID if you're providing passport details.
you need a letter from every job you're using for points. Put those into your work history. Everything else you put into personal history.
yeah you need a letter from your bank if you're going FSW. it needs to state when your accounts were opened, the balance over the last 6 months and any debt you owe.
you also need a medical and a digital photo
no harm to submit notice of tax assessments/T4's if you have them.
you can submit paystubs too.
if you have a common law I'd assume you'll need their docs too.
once you get ITA it asks if you'll be paying the $550 & $490 together. If you choose to do that you'll pay it all when you submit your docs after ITA. if not you'll pay the $550 when you submit your docs and the $490 when they ask for it.
