Hi Anchorman,
All of the answers are in Lasors, a fantastic book that the CAA have produced and is available either in book form or free online!
But I know that isn't very helpful and answer, so here's the explanation.
As the Transport Canada CPL/IR ME is a recognised ICAO CPL/IR your friend will need to undergo the following.
1) A full residential or distance learning course of JAA ATPL material.
2) Pass all 14 JAA ATPL Written Exams.
There is no getting away from the above, unless your friend had a full Canadian ATPL and lots of hours multi crew time then she wouldn't have to do (1) but would still need to do (2).
3) Training as necessary from head of training at the FTO to pass the the JAA CPL(A) Skills Test.
4) 15 Hour Multi Engine JAA IR course and skills test.
After that lot your friend would end up with a JAA CPL/IR with ATPL Writtens Passed. This is mis-known as a frozen ATPL.
If she would like to become an instructor then there is a JAA conversion course to do as per Lasors (Section H, Page 9, H1.10) entitled "Transferring a FI(A) Rating From a Non-JAA State Licence" but in essence requires a course of training at an FTO to include not less than 15 hours of flight training and 30 hours of theoretical knowledge instruction plus skills test.
Hope this helps.
Best wishes,
Charlie Zulu.
