Hi
You mean its an integrated master's course??
You can also check
http://www.credentials.gc.ca/ website. Try searching for your country, collage & course.
In my opinion you should get 25 points as you have completed masters and have 18 years fulltime education. Also post your question in doctors thread and PM someone from your occupation and country.
From the OP 06 processing manual
Section 10.2 – Education - guidance is provided on how medical degrees should be considered;
essentially medical doctor degrees are generally considered first-level degrees in the same way
as a Bachelor of Law or a Bachelor in Pharmacology. Officers should be guided by how the local
authorities responsible for educational or training institutions recognize the credential.
20 points.
