Fire on Canadian Submarine

This article from CBC News indicates that a fire onboard HMCS Chicoutimi is out, but the submarine needs a tug to return to port. As I discussed below, this sub is the ex-HMS Upholder, which was transferred to Canada this weekend.

For now, I just hope that everyone aboard is safe. More as I hear about it.
