There is no linguistic requirement in the Res. In the RegF, with the stated goal of a fully functional officer corps, officers who wish to be promoted beyond LCol must demonstrate a "functional" level in testing. There is no guaranteet, if you are on old dinosaur like me and came in before we started doing language training as an SOP, that you will receive any second language trg through the CF (I have received some): you are expected to develop your ability as a professional requirement. Language ability is a weighted scoring factor in rating RegF officer PERs at the annual merit boards. For WOs and NCOs it is also changing (especially, IIRC, for CWOs) but it is not as hard and fast for the NCMs as it is for officers. Cheers.
