A friend has two DUIs from at least 20 years ago.?
He cannot enter Canada under these circumstances. He could apply for a pardon, but that may not work. It would work with one DUI, if no other criminal activity happened, but then it did happen again. No country will take him because he is a two-time criminal who drives while drunk. The two times he was charged and convicted were the two times he was caught. He should probably just stay home.
