Unfortunately, jmt, the AOPS are not a good match for the coast guard. They are a bit like a swiss army knife: they have many tools but none of them is even close to the real one in capacity.
They are hybrid vessels at best. Capable of operating in ice, but not really ice breakers - river or arctic ; capable of patrol, but nowhere close to the level of a proper OPV that would be preferred by the coast guard for fisheries protection; not really capable of towing, at least not any better than your standard warship is; reasonable SAR platform, but again, not as good as a dedicated platform for such duties; and finally, and that is the last nail in the coffin as far as coast guard is concerned, they are not work boats that can carry out navigation aids servicing.
Personally, I think Irving's idea is:
(1) Bad;
(2) a feeble attempt by Irving at stealing work that belongs to Seaspan;
(3) a gross misunderstanding by Irving of the Shipbuilding Strategy, which is aimed at helping the industry to rebuild and modernize - which Irving allegedly has done - so it can then compete and obtain its own work in the regular market, not so the Government of Canada can be the only actual constant provider of work.
So as far as I am concerned, Irving can go fly a kite: If it has a bit of slack between two different GoC orders, that is exactly when it is supposed to get off its fat a## and get itself some real work. Otherwise, there is no point in the God damn strategy, and we may as well start getting bids again on every piece of kit Canada wants to buy to benefit from the competition.
