and on a positive note the processing times for work permits online are very fast - 14 days (new employer)

And I have read the cases on this forum when ppl have received BOWP without AOR .. So if you expect AOR(or are hoping and praying to get it asap lol) within next couple of days and your current work permit is expiring, start working on your application for BOWP not to lose any more time and to be able to apply for it as soon as you get an AOR.
Below is the forum with tips for successful BOWP application

Good luck to everyone still waiting for their CC to be charged and for AORs !! ;D
