Editor's note: A few years ago, the normal way to get a taxi was to hail one on the street. Now there are apps that allow people to hail cabs via their smartphones. Have you used taxi apps? You're welcome to leave your comments.

In Toronto hailing a cab is not hard, but I like paying by credit card. What's more, the drivers so far have been polite, courteous and professional. When I approach the car the driver addresses me by name to make sure that I am his intended fare, and the app knows when we are moving together and continues to track us both.
