DEF itself freezing is not a problem, as above, it is when it stays frozen and does not thaw! (but that usually indicates another problem anyways!).
On paper, it is not supposed to be a problem. I have operated in some COLD stuff in Northern BC, but not ICEROAD cold ... so who knows real world what will happen until it is tested/broken!
