I don't disagree with you at all that these things have to be retired responsibly. I think the retirement costs of these two new polar icebreakers would probably fall into the operations and maintenance over a 40-year expected lifetime, and the lifetime of these ships could be extended by refurbishment. Therefore, we're looking at costs that are, at the very least, 40 years down the road, or maybe 50 or more years down the road.
However, clearly when the decision is made to acquire new ships, the government should take into account the fact that these ships will have to be retired and dismantled properly to ensure that they don't pose an environmental hazard.
