Airline Pilot Central Forums - FAA to TCCA Study Guides

Edited to add: This site claims to have a study guide/ground school; short-cut compared to my drivel below!

Original Post:
The Transport Canada site can be a little difficult to navigate. It depends on what you're converting... i.e. a CPL or ATPL...

For the conversion exam for the ATPL you need to take a look at two study guides on the TC site. The first one is the Air Law and Procedures section from the ATPL study guide, link is here:

Study and Reference Guide for Written Examinations for the - Airline Transport Pilot Licence - Aeroplane - TP 690E - Study and Reference Guides/Sample Examinations - Flight Crew Examinations - General Aviation - Aviation Safety - Air Transportation -

The second one is a little more vague but suggests to study the "conversion topics" in the Instrument Rating study guide found here:

TP 691E - Study and Reference Guides/Sample Examinations - Flight Crew Examinations - General Aviation - Aviation Safety - Air Transportation - Transport Canada

If you're converting a CPL, you only need to look at the first section of the study and reference guide for the CPL found here:
Air Law - TP 12881E - Study and Reference Guides/Sample Examinations - Flight Crew Examinations - General Aviation - Aviation Safety - Air Transportation - Transport Canada

Now, those are just the topics tested, and most topics have numbers that refer back to the Canadian Aviation Regulation where you'll find the information. They're all online, and about as user friendly as the FARS online, so... meh. It is POSSIBLE to just use the online guide and then go up and look up everything, but it would take forever and you'd have to filter out a lot of crap you don't need to know. I haven't seen a specific book or program (i.e. like the Gleim has done for Canadians converting to FAA ATPLs) but you could always buy a study book that is used for the full license (two, in the case of converting an ATPL) if you had the cash, and just studied the appropriate sections needed for the conversion exam.

Examples here:
Canadian Commercial Pilot Answer Guide<br> 6th Ed. - VIP Pilot Centre

Canadian Airline Transport Pilot Licence Workbook - VIP Pilot Centre

Canadian Instrument Rating Workbook Sixth Edition Revised - VIP Pilot Centre

Anyhow, I hope that helps. As a disclaimer, I haven't done this myself (I am just going through the TC to FAA ATPL) but that should be a place to start for you. Hope you find something a little more helpful though. (And just a note, TC doesn't publish their test question bank like the FAA does, which kind of sucks... the questions in those study books above are quite similar to the actual questions though... and I found that the TC exam questions are more "wordy" than the FAA ones... requires very careful reading of the question.)
