SYDNEY, N.S. It s been more than three months since the last commercial flight touched the tarmac at the Sydney airport and now it looks like it could be a while longer before the service returns. Air Canada has communicated that the Toronto flight that was scheduled to start June 2 is now pushed back to June 26, said Sydney airport CEO Mike MacKinnon. Flights to Halifax will not start now until at least July 1. PAL Airlines who had been planning to start flights three times a week from Sydney to Halifax on May 31, have also been grounded. Nobody wants to restart service and then have to shut it down again, MacKinnon said. I d rather we do it right and when the time is right and when we can do it safely with minimal disruptions going forward.
