Licence Conversion Process for Students holding a Foreign CPL
1. Your foreign licence and medical would both have to be valid to get a Foreign Licence Validation Certificate or to get a Canadian PPL. Canada cannot directly issue a Canadian CPL based on a foreign CPL that is not FAA issued.
2. You will have to take a Canadian medical as appropriate for the CPL and then a 50-question regulatory examination. You will then be issued a PPL, based on your foreign Licence. With this PPL you must complete your CPL training (65 hours) and have met the experience required (200 hours-including your foreign experience), before taking the CPL examination.
