i just want to clarify somethings for those who are replying. my ex wife wouldn't move to canada. we are from australia we enjoy similar wealth and lifestyle down under. average income in aust is around $50,000 and dollar value on par with USD currently, and she is settled here. with us separated she wouldn't be interested in moving to canada. about seeing the child i hope she can but under family court she would have to. i am concerned if she wants to be nasty what can i do, where do i stand in canada and her visa to canada
If she's not moving then what's the problem? Even if she visits Canada to land she can't return to Australia and then claim services from the Canadian government. Also, if she does land and get her PR it will only remain valid if she lives in Canada for 2 yrs out of every 5 yr period thereafter.
Honestly it doesn't sound like you have a problem if she's not moving, either way though I don't believe sponsorship can be revoked once a visa has been issued. What about your child? It sounds like she has custody, but perhaps you could make an argument that you should be given custody for extended periods so that the child can fulfill his/her residency requirements so that he/she retains PR.
Just a note, you should speak with a lawyer regarding what documentation you will need to travel internationally with your child. I know Canada does not like to let parents leave the country with a child unless both parents are present or the present parent has a notarized letter giving him/her authorization to leave the country with the child.
