on July 31, 2012 I was treated the worst imaginable by Air Canada at the Toronto airport. They grounded planes, left thousands of passengers stranded for at least 24 hours. There was no communication and long lines that did not move. I stood in line for 8 hours to try to get rebooked to continue my short vacation in Newfoundland. I ended up booking a reservation on West Jet to get out of Toronto, thus incurring $700 more for my travel, no thanks to Air Canada. Then, returning home yesterday, Air Canada left St. John's, Newfoundland an hour late (this was supposed to be a 6 AM flight) with no explanation to passengers, causing us to miss our connection on a direct flight from Toronto to San Diego. Our travel time was increased from a 12-hour day to a 20 hour day, no thanks to Air Canada. I do not recommend anyone to fly Air Canada. They are the worst airline company I have ever experienced and need to get their act together!
