I know that IRCC might want a proof of that you have lived in Canada for at least 3 years, but I just don't understand if there is any standard for them to do this request. A friend of mine travelled only 2 times abroad and has so many days over the minimum required to apply, but IRCC still requested for copy. I did not get this request yet, but maybe they will send to me. I have seen so many people getting it and this might delay the final decision. What you guys could say about this matter? My friend who travelled 2 times abroad does not have any stamp in his passport because he travelled to the country where he is from.
