I am currently a PR and am submitting my citizenship application online. It asks me to list all of the dates I have been out of Canada in the last 4 years? What if I haven't kept track of all those dates? I do know the dates when I went out of country to visit family, but there are several times of year when I go from Canada to Buffalo, NY for just a weekend and I don't have a record of those dates. Is there a way for me to find out those dates somewhere from border crossing records? Thanks in advance for any help!
