You will have to complete-
1. Another Flight Test
Then depending on your hours...............
2 (a). All seven written's (I think if you have LESS than 100 Hrs)
2(b). Three written exams (again I think, if you have 100+ Hrs)
The Canadian PPL will be treated as an ICAO licence and therefore no special deals. Is there ever???
You should read the current thread which is some thing like 'The end of JAA PPL's in the US' as it has a lot of good info regarding conversion. However, do disregard the slanging match which is in full swing!
