We have a vulnerability this winter and next winter. Beyond that we do not expect our situation to be any more vulnerable than that of any other country. We are fortunate that we still have an indigenous supply. [Interruption.] It may be declining, as Mr. Duncan says from a sedentary position. We may be a net importer of gas—but of all the G7 countries, only Canada is not a net importer of energy. I think that we will be in a position similar to that of other countries. As for malicious attacks, if the hon. Gentleman is talking about terrorism, we have long-standing measures in place to protect against that, particularly at our nuclear facilities. We believe that those measures have worked, and will work in the future.
