I am just about to submit my application for permanent residency under common law sponsorship. I need to submit a copy of my last entry stamp into Canada however immigration did not stamp my passport when I arrived. This presents 2 problems - I cannot provide evidence of my last access into Canada for my application, but further I do not know how long I am entitled to stay here as a temporary resident. Can you therefore tell me firstly if this presents a problem for my application (if I explain the situation) and secondly how do I find out how long my visa is valid for? I am assuming 6 months from date of entry but how can I verify that? (I do not want to overstay my welcome!) I have tried calling the CIC helpline but as appears to be the norm - I can't get through, it just kicks me off the line!
