Ballistics- You should look into getting any technical qualifications recognised by a Canadian institution, this may cost some money but will make it easier for the CF to assess your skills and training. Also you should be prepared to submit your ENTIRE service history (assessments, reports, course reports, certificates, any discharge paperwork) to the RC. If the Romanian Army did not provide you with any of this and you did not keep copies, unfortunately you are SOL.
Just a note to others in the same situation as Ballistics:
NATO does not necessarily guarantee the same standards, doctrine, or TTP's between all member countries. Therefore finding equivalencies may not be as easy as one may think.
It is generally easiest to transfer between ABCA (Australia/NZ, Britain, Canada, America)countries, due to the commonality of doctrine, tactics and culture. Also, foreign ABCA training is easier to compare to CF qualifications for relevancy. The process for finding out if such equivalencies exist is known as PLAR (Prior Learning Assessment Review), where an applicants former service is assessed by Director Army Training, and equivalencies outlined in the offical offer.
That being said, should one find themselves joining, with previous military experience, but no equivalencies granted, if you are truly keen on serving in the CF, take it on the chin, knuckledown, and once in the field army/air force/navy, your experience and different skill set will allow you to bring something more to the table, and provided you aren't crap, your career ''should'' be adjusted accordingly. Transferring from the British Army, I took it as worst case having to do BMQ/SQ/QL3/5/PLQ over again, and should that have been the case, taken it with a slice of humble pie and treated as a nice refresher course! Luckily that wasn't the case in the end.
