In your opinion, what is the most important change that should be made to the parents and grandparents immigration program?
Require that the majority of their children live in Canada
Require parents and grandparents to pay higher fees to cover the cost of social services
Require sponsors to be better financially established before they are eligible to sponsor
Require sponsor to be a Canadian citizen
Require that the parents and grandparents be able to communicate in one of Canada’s official languages
Allow only those parents and grandparents to apply who are fully financially dependent on their sponsor and have no other close relatives in their own country who are able to assist them
Other, please specify:
