Mr. Chisu, thank you for the question.
In terms of the defence mission in the homeland, be it in Canada or partnered with the United States, the perennial and persisting challenges include natural disasters and the requirement to provide for the safety and security of Canadians in the face of natural disasters; and man-made disasters, be they accidental or deliberate, in particular when in comes to hazardous materials and what we've seen recently, for example, within Canada itself in terms of man-made disasters.
In the homeland we're challenged to ensure that we provide for the aerospace defence mission and to be confident that we're on top of aerospace threats into the continent. Clearly, NORAD is leading in addressing that particular challenge. Approaching our nation are threats and challenges that can be related to illegal immigration, transnational criminal organizations, and their influence within Canada and North America. And last but not least, we remain responsible for and capable of providing for the defence and security in our maritime domain on the approaches to Canada. Clearly, we're undertaking that responsibility with our maritime security partners, as well as our American partners.
Within the homeland, man-made and natural disasters keep us preoccupied every day. We are preoccupied every day with the approaches to the homeland aerospace and maritime space, and with the human networks or the threat networks that know no boundaries.
