un-know information about family

[Canukdiver]

It's kind of sad. But I do not have any contact nor know where about of my family in Canada. Now I am planning to sponsor my wife. If there are any question that I do not know the answer about my family member, what do I do on the form ?

First try to find the info. If you cannot, then just put as much info you do know, then attach an explanation of why you cannot provide the rest.
