Well, every Canon DSLR I have ever owned, or used for an extended period, (there are several including pro and consumer models) have failed me at least once resulting in lost photos and/or opportunities. My Leica M8? Never. If I were to follow your thinking I should never touch a Canon camera ever again and stick to Leica's.
You probably shouldn't touch Canon. There are plenty of other fine choices like Nikon. On the other hand I've used Canon professionally for about ten years now and put some heavy use on my cameras without a single problem. Then again I've used leica M's professionally for 44 years and many thousand rolls through them and the only issues have been current equipment made since the 80's. This includes lenses that weren't made properly and would not focus to infinity on any body (summilux asph 50), a 35 v4 that came apart, 90 asph summicron with defective focusing mount, 50 summicron with poorly cut helix in the focus and a new a la carte MP that the shutter failed on within a couple of hundred rolls.
Enjoy your M8, you have one that works.
