thanks for the info! i think i'll just wait. I had had a memory from somewhere that it can take a long time (months) to get an appointment, but if that's not really the case, then I guess it makes no difference.
Another odd question, My spouse and I are both applying for PR, and we have a child, who was born here in Canada while we were on TFW. I know CIC states that all dependents must get medicals, but I am assuming that since our baby is a Canadian citizen, this won't apply.
