Hi,
during the AEO process HRSDC/SC will contact your employer by phone.
If they have questions they will ask them, you don't have to send in the extra info with your application.
But, with AEO your are still not certain of an appoval for your PR!
I also read on this forum in "arranged employment opinion 2010" that Pinck got her AEO approval without HRSDC/SC contacted her employer...
But if you feel better to send in some extra info, than you must do that!

Be aware that the processingtime for an AEO approval is LONG these days....some of us are waiting for over 7 months!

If your employer doesn't mind to wait that long, because you cannot work for him in the meantime, than no worries and apply for AEO.
Good luck!
Regards,
Louise!
