My anecdata (owned 8-9 dSLRs) suggests they're pretty robust. I haven't had a dSLR fail on me yet. The oldest camera I have is 21 years old (no longer used, but still works). The oldest cameras I still occasionally use are 12-13 years old. My current main cameras are about 2-3 years old. And they are not being babied. I've dropped cameras several times, I regularly use them in pissing rain, and in the winter they are occasionally subject to arctic temperatures (record is a bit below -30C).

My main one, a D700 on "extended loan" from my dad, was used in Iceland in winter (multiple times), in pouring rain, near the Atlantic shore during storms, in the Sahara during dust storms and 45 degrees C, used professionally for event documentation... And that's just from top of my head. Still shoots 10ish fps with the battery grip, has no sensor issues, is still weather sealed and just works.

Same for the old F4 sitting in a shelf, or the D750 that replaced the D700 for my dad. I have no reason to doubt Canon is any different (during a lot of those trips other people used Canon, and those held up just fine as well), nor do i have doubt the new mirrorless cameras will be any different. Unless you dump them for prolonged periods in salt water after having them run over by a truck and store them in a warm and humid environment without drying.

This. These things tend to be incredibly well built. Not indestructible (Unless you get say, a 7D), but people rely on them for their livelihood and they're built as such.

I've had the mount on a Nikkor 24-70mm break off while attached to a Nikon D4 due to an accident. The camera body was completely fine.

Then again, the D4 has a skeleton underneath the plastic and rubber surface that looks like the skull of a killer robot: https://commons.wikimedia.org/wiki/File:2012_Nikon_D4_magnes...
