When we talk about pollution, it's always a concern. I wouldn't be doing my job properly if I wasn't concerned about that.
In Canada, there's a principle called “the polluter pays”. The operator of the vessel is responsible to clean their own pollution. If they don't act properly, then we step in. The people who operate in the Arctic are very responsible. Most of them are actually resupplying the communities, so they do not want to leave a trace behind. They are well equipped, but we have equipment on our ships as well. We have equipment, as I said, in many caches across the Arctic. We train the local people so they can take action right away if something happens. If we take a number of hours to get there, action can start immediately.
From experience, whenever there's been a spill, the operator steps in. They do some training with the communities as well.
