I was a Canadian Permanent Residence from 2014 till 2019. In 2015 I also received my US green card. I did visit Canada twice, once in 2014 and other in 2016. Both times I was asked that when will you move to Canada and I told them that I will move in next couple of months. But I did not move and I stayed back in USA because of my job. Recently I got my US passport and I want to visit Canada again. I am just curious to know that now when I come Canada on US passport, what kind of questions will they ask me? I am 100% sure that Canadian border officials will know that I had Canadian Permanent Residence from 2014 till 2019. Will I be in trouble for not moving to Canada? And if they ask me that why you did not use your Canadian Permanent Residency, then what should I reply?. I will be landing Toronto Pearson International Airport
