Link?
I've never had to make a warranty claim on a Canon, anyone else?
I've had quite a few Canons throughout the years. I've had issues just once. It was my Canon 880 (fav point and shoot ever!) which after I owned a couple years had an issue after the case got thrown by someone who didn't realize the camera was inside. It wasn't under warranty but I paid $100 to have it fixed by Canon. Still working great.
Otherwise no issues.
In general the only time you should have an issue is if you damage the camera yourself somehow.
My current SLR is few years old and cost me around $310 from Canon refurb and it still works great.
