If it is of any help. The requirements to get the Canadian CPL (I hold UK ATP, Oz ATP etc)was to 1. Sit ALL the exams again at TC's office in downtown Hong-Couver 2. Flight test with approved examiner at local flight school. 3. New medical. 4. Audiogram.
TC only recognised helicopter types flown in last 12 months. For ATP(H) 2 additional exams were required. Talk to heli-college in Langley or someone similar to get the latest prices Hope this helps some.
