hi sisters,
this is good news.
The Canadian Embassy can now request for extension of the Medical Exam validity for another 12 months if the reason for the pendency of visa issuance is an about to expire Medical result or an Expired Medical result.

So, at least, we wont have to redo it again in case our Medical Exams expires.
The only thing I am scared of about this is that, maybe the CEM will no longer be pressured to issue the visa immediately as a request for extension can now be done. This will also give them enough confidence not to hurry up for the processing because there is no more pressure of an expiring medical exam.
