The visa issued to me, and my wife expires on Oct 22, 2009.
We expressed concern to the Canadian consulate that we are expecting baby around this time and need extension of landing date. To this request, they issued the letter.
My medicals have expired, and I understand that I'll have to undergo medical exams again. However, Canadian consulate will send me new medical forms to undergo tests again, and I don't think I can undergo tests NOW.
Can I 
My question is, at this time should I just return the 3 things they asked for the baby OR
do I need to refill any forms(like application for permanent residence, additional family info form etc)..
