One of the most frustrating parts of camera ownership is you can't be sure if or when your camera might break. Cameras usually come with a manufacturer warranty from the date of purchase that covers against anything that might go wrong from manufacturing defects, but this usually only lasts for a year, with Canon offering a more generous two years on most products.
Cameras, especially in professional use, can be put under a lot of stress, with lots of moving buttons, dials, and other parts that can easily fail when used repeatedly. So it is good to know when buying a new camera just how long you might be able to get support, after your official warranty has ended.
