Hi, I'm a Canadian citizen (born here if that matters). For the past year and a bit I've been studying in the UK, coming home about 3 times/year. Every other time I've come home I've written my Toronto address on the landing card and then filled in the residents section (where it asks you the value of goods you're bringing in). Every other time the CBSA person has just let me in no questions asked. Yesterday when I flew home for Christmas the agent yelled at me, saying I should have written my UK address, then wanted to know how long I was planning to stay in Canada, crossed out the resident section I'd filled in and filled in the visitor section and wrote a big V on the card, saying I was a visitor. She even asked the next person in line if he knew me and told HIM that he should have told me to fill in my UK address which I found very inappropriate. She was extremely rude and aggressive the whole time but that aside, I'm wondering what the policy on that is for the future. I'm a citizen of Canada and the UK does not consider me to be a 'resident' because I'm a student and I come home to Canada every few months or so, often staying 1-3 months at a time so I split my time about 50-50 between the two countries.
