You're welcome. I don't have an official answer here, but please see what I found below. Other more experienced members may be able to confirm.
Note: I would think a DMP knows what to do. Anyway, the DMP should double check with their official contacts. There are some contact information in Appendix I.

Medical Instructions
The doctor will sign the form and mail the first copy to the Canadian Regional Medical
Office (RMO) with the results of the examination. You will be given the second copy as
proof you underwent the medical examination. You must include this copy with your
immigrant application when you send it to your sponsor. Photocopies will not be
accepted.
