I've been in Canada since '05 from the US. My spouse was sponsoring my PR and I received my work permit but now we are splitting up and she has sent a letter to CIC withdrawing her sponsorship, about one year ago. I recently got a letter from CIC saying that it has come to their attention we are no longer living together and I have thirty days to respond to them. It's interesting that they just didn't say my application is cancelled. What can I say in response? Can I get some extension of my stay here to take care of the many ties I've made from living here legally for 3 1/2 years?
