Thank you, Madame Vignola. Those are great questions.
Are two polar icebreakers enough for our capacity in the north? Well, it would be a fairly straightforward replacement of our current capacity. It wouldn't be a real expansion of the capacity. Right now we have two heavy icebreakers, or at least that's how the Coast Guard rates them. One of them, the St-Laurent, is more powerful than the other, but they're both rated as heavy icebreakers.
Right now, to the extent that our Coast Guard is able to meet the requirements of the north, replacing them one for one would suggest that it's also enough, but of course we'll have increased traffic in the north and an increased need to have more capacity. If I had it my way, definitely three heavy polar icebreakers would at least be a good start.
It's worth noting that a lot of this depends on the quality of the medium icebreakers that are also going to be built. Will they have an increased icebreaking capability compared with the current medium icebreakers? More importantly, will they be more available because they'll be newer? In essence, that will provide greater capacity to carry out important operations up in the north.
