Canada recently discontinued the requirement for Mexicans to have Visa's to enter Canada. I am hoping this paves the way for the reintroduction of Calgary - Mexico City direct flights. When the new terminal opened the CAA indicated they were actively pursuing direct Calgary - Mexico City and Paris flights. Would be a much better gateway for South America than Toronto and will allow for skipping the USA/Houston. Trans Canada has a few infrastructure projects in Mexico (in development and operational) that should induce business traffic to use the route. I would guess AC needs to jump on the route although that means traffic off of their Vancouver Mexico City flight.
