Coinciding with the implementation of eMedical, will be the release of GCMS 4.0 which will include new medical screens. As of November 1, 2012 the new medical examination forms will be disseminated to all panel physicians.
With the release of the new GCMS 4.0, it should be noted that all previous versions of the IMM 1017 form as well as the Appendix C will no longer to be used. With this release, there will be two newly-revised IMM 1017 forms:
IMM 1017: Medical Report: Client Biodata and Summary (not available on our website as it will be GCMS-generated along with medical instructions)
IMM 1017B: Upfront Medical Report: Client Biodata and Summary (not available on our website as panel physicians will have these forms in their office. With the implementation of the new IMM 1017B, Appendix C will no longer be required)
So it sounds to me like the only thing you need to bring are the photos. Doctor should have all the necessary forms which they fill out internally, and then for a receipt you get a copy of the filled-in and signed IMM1017 which you then include in the app. Like before, no need to wait for results as everything is electronically submitted to CIC.
Of course with panel doctors all over the world... i doubt CIC has properly ensured all of them (and their secretaries who most people probably talk to first asking for info) understand the new rules. So i'm not surprised to hear of some confusion still since the rules changed.
