Hi. I'm from Italy and I want to visit my relatives in Canada, they are all Canadian citizens. I have been in Canada before (in 2006). While applying eTA, i found that paragraph where i should write UCI, previous canadian visa or permit number. I don't know what i should write. In my old stamp i can only see the date when i entered Canada and P.I.A/A.I.P code. What should i write? P.I.A/A.I.P code? I wish i could send photos with stamp but seems I can't do that here.
