The Globe and Mail reports in its Monday edition that every day at airports across Canada, thousands of people are being denied their flights simply because their name happens to match someone else's name on the no-fly list. Guest columnist Stephen Evans writes that this is not just bad for Canada's national security and undermining the integrity of our intelligence with our allies. This is bad for Canadian business. There is no information to uniquely identify a person, and there is no redress system for those who are falsely flagged on it. Any Canadian who has been falsely flagged on a U.S. no-fly list has access to a U.S.-based Department of Homeland Security Traveler Redress Inquiry Program, otherwise known as DHS TRIP. As Canadians, however, none of us have access to a similar program in Canada when identified as a "false positive." From a business perspective, this is mindboggling. If you share a name with someone on the list, you are flagged. The solution to this problem is not terribly complex. We already know how to identify individuals in Canada. We can use passport or social insurance numbers, for example, as unique identifiers. This information could be added to the no-fly list.
