OK SCM consists of several separate exams. They do not recognize any older university diploma from abroad.
So it can take some time to get it done. If I remember well they offer like 5 or 7 different modules with an exam at the end of each and then like 1 week (or just 1 weekend) of case studies (face to face meeting). Each exam is written separately and each costs.
I did calculate the whole fun to about 5-7k CAD (that is if you are not force to repeat any of those exams). And you need something called guarantor.
In reality it is not a must to get into the industry. Some prefer it but not all.
