Q: Are they available at all times of the day? I will be there 9pm?
A: Yes it is. You should have no problems. If you don't see any around the arrivals area, then you can ask an airport employee to call you one. There will be some there though, I'm sure of it. According to the Halifax Airport website, a one way taxi ride to the downtown area will cost you $53 CDN. The link provided also has a list of cab companies that service the airport and allow you to prearrange a taxi. http://www.hiaa.ca/images/pdf_files/2008/Prearranged%20List.pdf Have fun and enjoy your trip!
