The only one that I can remember was in the mid-nineties, for which actually the Coast Guard came over to Fisheries and Oceans. There was a look at all the fleet in Canada and then my understanding is that the decision was to merge the civilian fleet, so the DFO fleet and the Coast Guard fleet, but after the announcement, the military was left on its own.
