I'm going to fast-forward to my recommendations.
We will likely see an increase in family class sponsorship applications, particularly as Canada's foreign-born population increases. Family reunification has been credited as one of the reasons for Canada's success in attracting and retaining so many experienced and highly skilled professionals. It's a popular and well-used aspect of Canada's immigration program from as far back as the 1950s, when Canadian residents sponsored thousands of dependent relatives.
Apparently over 90% of the people sponsored at that time were Italians and their sponsored relatives. The settlement and integration experience of Canadians of Italian origin is evidence of the success of the family reunification model. In fact, parents and grandparents, like most other sponsored relatives, bring their knowledge and skills as well as a commitment to Canada.
There is no evidence one way or the other that speaks to the benefit or the downside or the cost of family reunification or bringing in sponsored relatives—parents and grandparents—so it's really hard to conclude that they will be a drain on our economy and our resources.
