What was the temperature. The 6D's operating temperature is recommended at from 0-40C though I feel that it is not too rigid.
Doh - does this happen often? I have shot up to -10 degrees Celsius this winter, I hope I didn't risk the shutter because that wouldn't have been worth it (my 60d is also 0 to 40 degrees C).
Operating below the suggested temperature will not result in any permanent problem. The camera can, in theory, stop functioning temporarily and/or report a freak error.
The main reason I say that because i believe that extreme cold can possibly affect the mechanical movements in a camera. Saying that, I've shot in -15C this season with the 5d3 without any problems. Can't say about the 6D as it has not been in the extremes yet ... It will suffer from heat though, close to 48C + this summer.

I have more photo gear than I need. The blame lies squarely with Canonrumors
