As Quoted on my Medical Form:
" The medical examination must be performed by an IOM Canadian Health Assessment Panel Physician. The results of your medical examination will be forwarded to a Canadian Medical Officer who provides an opinion on your medical condition to a Visa Officer who will examine your application. The IOM Canadian Health Assessment Panel Physician cannot provide any further information related to the processing of your application.
Certain medical conditions may require further investigations and you may b referred for additional tests. These tests are part of the satandard medical exam and are based on guidelines set out by the canadian Medical officer. The IOM Office will forward all medical results directly to our Medical Officer at the CHC, New dehli.
Here it is mentioned in certain conditions,, so what do you say??
