I flew into Vancouver from Las Vegas on the 6th of December for a medical consultation and was issued a Visitor Record to only cover the dates in my itinerary (06-12-2009 to 08-12-2009) because the customs people suspected I'd stay for good. I left on time but I did not check in with CBSA before leaving the country as specifically stated I do so in the remarks secton of the visitor record. The remark reads "Must confirm departure at CBSA front office at Vancouver Int. Airport on or before 08DEC2009 with boarding pass 3 hours prior to flight." I didnt check in because I would have missed my flight if I did so. Will this be a problem for me down the road when I want to visit Canada again? Thank you
