My wife and I are going to Mexico next week and we just found out that her card has expired. I'm a canadian citizen and she is polish with a valid passport. She did realize that the card expired since she has only use it once when she first got it. She has live in Canada ever since she arrive here in 1997, so she has meet all the pr obligations. I know we can go get a TD from the canadian consult in Mexico City but we are going to cancun so it not that easy. My question is we are traveling with west jet and do you think they will let her back on plane in Mexico back to Canada with out a TD. I'm not too concerned with customs in Canada because we are going to bring lot of back to confirm she has been living in canada( letter of employment, bank statement, t4 and marriage cert). What are the chances that they won't let he on the plane.
