It's important to remember that there was supposed to be a batch III of Halifax's, IIRC stretched from the original to have 24 VLS Mk41 cells in front of the bridge for SM2's, but when the Mulroney government put out his White paper on defense calling for nuclear attack submarines, that batch was cancelled to be replaced with the subs. Then the wall fell down, the world changed and the White paper - in the middle of a recession - was forgotten, but the Batch III never reinstated. Mulroney retired, Kim and her conservatives were wiped out by Chretien, and he was just has happy as could be to not reinstate the ships the Navy then said they should get back since the submarines were canned, to placate his finance minister that was tasked with cutting the deficit.
