I called to CIC today about my Work Permit for the same employer (to renew my WP) and CIC told me - my application for WP approved on July 15th and even told me my Work Permit number. But I still haven't it (during 3 weeks). And CIC agent told me - wait till Aug 25-th, and then if Canadapost lost my Letter (Work Permit), I can apply for another copy only in 6 weeks (from July 15th - Work Permit was issued - till May 16th 2012)
I come to Canada Feb 16th 2008
I sent my application for OWP and PR on Aug 16th 2010
I sent application - RENEW my work Permit for the same employer - March 7th 2011 (because I need SIN number and Health card, and Driver licence - everything expired on May 15th 2011)
And now I have (God Bless) Work permit till May 16th 2012 (but I haven't it on my hand - but application was approved and CIC sent me it by regular mail)
My English not so good and thanks for your patient
