I have been a Canadian PR since 2009, but only recently started living there permanently.I am trying to calculate my days of residence, and need help with that. I live on the US Canada border, and have made many day trips to the US, sometimes staying overnight. My question is, how are the days calculated? Is any time spent in a day considered a full day for PR purposes, or does it have to be an overnight stay. And how about short trips to the US ( a day or two overnight) Are they counted complete days out of Canada, even though I have all utilites and rent stuff going on in Canada, and my kids go to school in Canada. I mean we do actually live in Canada, but at the time of renewal of my card , I will just be on the borderline , if these day trips are counted as complete days, I wil be safe!
