It's a big question and an important question.
The first thing I would say is if we consider the relationship in security, defence and intelligence with the United States as a home we built on both sides of the border, and there are 40 or 50 rows of cinder blocks on the foundation, the 30 bottom rows of those cinder blocks remain absolutely untouched. There has been no frost heaving, no leaking, no heaving or shifting. That relationship is fundamentally strong and continues.
Remember that we have the only binational command in the world: NORAD is the only binational command in the world. It's a great privilege to be able to work with our American neighbours. Canada is going to continue to manage that relationship very carefully. There are some very big modernization investments going on in surveillance systems; threat identification; response speeds; ability to deter and defeat aerospace threats; ensuring that CAF can deploy and sustain a strong military presence across the country, including in the north; future-proofing NORAD's ability to defend North America through investments in science and technology; the over-the-horizon radar system, which I mentioned earlier, the first tranche of which is about $6.5 billion. The list is long.
All of this will allow for Canada to dig down and t build a defence industrial base which is ready for takeoff and for growth. We have 600 companies now in this space. Personally, I'd love to see that doubled. That's my personal ambition, if we can get there, or at least taking on companies that are significant players and doubling their books of business. This is also why we went to the European Union and signed on to the SAFE agreement, which is a $1.25-trillion marketplace for defence over the next decade.
There's a lot of opportunity for Canadian businesses here, a lot of job creation. I think we all know that, and we're very excited by it.
