I was happy when I heard we were going to build ships that have the capability to operate in ice-infested waters. Our naval vessels today cannot operate in the Arctic in any kind of ice-infested water, and because they don't have a double hull, they would break Canadian law if they were to be deployed in the high Arctic.
If those ships are capable of operating until there is one metre of ice, it would cover most of the maritime activity taking place during the period of time the various passages are open. Once the ice is thicker than one metre, the amount of maritime traffic you would see is reduced significantly. At that point, they can reduce the amount of patrolling that takes place. It would be seasonal in many ways, but it's a capability we don't have right now. I think any increase in that capability is very significant.
