What are tax residents?1) No declaration to be made for assets at the time of flagpoling
2) You do not understand! They only need to know the value of their assets when they become tax residents. If they don't become tax residets, then they do not need to make declarations
Others) I suggest you get a professional accountant to sort it out preferably one who specialise Canada/India taxation.
I have a similar question: If parents have a house, which they may sell in later years after becoming permanent residents, should they mention it in goods to follow list at the time of their landing in Canada as permanent resident?
