hay guys I think i got the fastest medical reply so far ..
drop my application on : 13/july
Got my medical : 21/july
took 7 days only ...
will take the appointment tomorrow ..
well i think following is your last time time line
applied on 20th oct. 2008
Medical letter on 30th oct 2008
re-submitted my passport on 10th Nov 2008
So as per CHC policies your medical is valid for 12 months so i think you should wait for a day or two but get an appointment from Dr. ( on another forum sabirna re-applied for study permit and they told her not to go for medical again and keep the passport )
here is her post i just copy for ya
"I recieved medical papers on 14th July 2009
Got call to cancel my medical appointment on 15th July 2009 as they already had my valid medical of last year. I asked them to return my passport but they wanted me to keep it & said that they will inform me for that later."
