Umm, no, they didn't. There isn't an airport at Concord. They fly in from Louisville to Mount Hope, then sorting at Concorde, then back to Mount Hope if they need to fly out again.
I never understood why they put the distro centre at Concord and not right by the airport (they're about an hour apart).
But, there's no way it went from Hamilton to Kitchener in an hour and stopped anywhere else, so they must be doing some sorting at the airport now. Here's hoping that they take Concord out of the equation...could speed things up by a couple hours for the rest of the country.
