I applied to extend my work permit in Canada last month, but I am still waiting for a response (its taking around 60 days) I applied with my old passport which will expire on november 2015, but last week I renew my passport and I have a valid passport until 2020, so I wanna know if I need to make a "Case Specific Enquiry" https://secure.cic.gc.ca/enquiries-renseignements/canada-case-cas-eng.aspx?_ga=1.127045389.1685498281.1401303249 to adivse the change and maybe get a work permit for three years (my contract) or I must wait to receive the work permit that I applied (probably until november of this year because my old passport expire that time) and the reapply for another work permit using my new passport. The problem is that I have a new number of passport., thanks
