I am a Brit with an EASA B1 licence. Transport Canada does not recognise the EASA ticket or the CASA, you have to sit all the exams again.
Contact TC in Ottawa and based on your current coverage they will give you an exam to give you the Canadian equivalent AME licence.
Although you have to prove 1000 hours ground school etc etc, I couldn't so I passed a ICS Canada course to give me the right to sit the exams.
You cannot sit the TC exams outside of Canada or without the TC permission form 26-0638 signed by a TC surveyor.
Take a look at the Transport Canada website. I'm looking for a job in western Canada myself.. I have the PR card already.
