I have a colleague who has a foreign ATPL license with a lot of experience (Currently 744 CA).
He is doing a move to corporate and is supposed to get typed for the Challenger 350 in CYUL
The Boss wants him to do this on an FAA license and not his ATPL

The procedure is, to my understanding, getting a medical, ATP written, doing the Foreign License Verification and meeting with someone at an FSDO.
I understand that since 2014 and the new rules change there is also an ATP-CTP course that needs to be done.
My question is does anyone have any experience with this? any way to avoid doing this 4000$ish course that is totally a waste of time and money? Can the Type rating count instead of the course?

Any advice or previous experience would be appreciated
