flash8 ........ you've done well to be flying a 737 in Canada and still only have 1400TT !
Anyway, back to your query. A conversion if you have (I believe, as it wasn't applicable to me) more than, it was either 1500 or was 3000 hours of medium/heavy jet multi crew time, then the conversion is a straight forward paperwork filling out exercise.
If you don't have fullfil this requirement, then I'm afraid its the 14 exams, CPL flight test (no minimum hours required for this - discretion of FTO) and a MEP IR (minimum 15 hours training of which 10 can be in an FNPT II sim) and then of course pass the flight test for it !
So, a royal PITA I'm afraid, but perhaps with your experience worth it !
Good luck.
