Dear Zen2x, I politely contradict with your answer no 2.zen2x said:1. If your parents are also coming with you then yes, they should be included. But if it is just you and your wife and your daughter then that should just be 3.
2. Yes
3. Again, if they are going with you in Canada, yes, parents should be included.
I am sorry, but please refrain from posting your message over and over. All the people here see your message and will answer. Please be patient. Thanks!
In IMM008 form, there is a separate question about any NATIONAL ID DOCUMENT where the re is also another separate question about PASSPORT, its no, exp date etc.
Since the questions are separate, Its general assumption that Passport as national ID document wouldn't be viable in this scenario.
