Thank you.
I don't know enough about the ice storms in order to make a judgment of whether or not there could have been opportunities to respond more effectively. Let me say that in Halifax today that is one of the scenarios that's being addressed, the rise of severe weather hazards and what can be done to invest against them to strengthen good resilience. That's a prime focus now of regulators and industry both in Canada and in the United States.
With regard to separating the network and building firewalls more effectively, this is an extremely important opportunity for progress. Let me say again, my personal view is that even if we invest in the protections that we should be making, eventually the offence has such an advantage in the cyber realm. Eventually there will be opportunities to penetrate software using zero day exploits or other openings by the attacker so that in addition to building protections, we must invest, we must plan for restoring the grid, restoring the flow of natural gas after an effective attack occurs.
