hehe, our parents never want to go Canada, they have their friends, relationships...
It is more happy for old people to live in their oringinal place than immigrate, unless just for visit.
so, immigrate your wife's parents. let her and your parents-in-law try "how good" life here.
many times, I saw old guys take bus for fun, look straightly to one thing while sitting aside the street...
is that a good thing?
