As you mentioned, Bombardier is very focused on markets outside Canada. Canada is obviously an important market. It's our operations base, and it represents about 7% of our revenues. So market access is critical for a global company like Bombardier. Our competition is global. There are a few players in the rail sector and a few in the aerospace sector, but they are big players. We are constantly going head to head with them no matter what market we are doing business in.
The value of the TPP for us is that of a base that can be expected to grow. That is how we understand it. Several areas are covered. There may be areas where we could grow more. I understand that there are defensive and offensive interests. I think a balance has been achieved, but it is certainly a good basis for growth.
It is sometimes difficult for companies to get a feel for that group of countries. For us, in fact, Canada's entry with NAFTA members was critical. We could not be excluded from that agreement. It's an opportunity to strengthen the North American platform and preserve our privileged access to the NAFTA market. There was definitely interest at that level.
Furthremore, I think things changed when Japan entered the agreement. There are offensive and defensive interests with respect to Japan. We are very active in the aerospace sector in Japan, but less so in the rail sector. We have about 70 regional aircraft in operation in Japan, and many of our clients are subsidiaries of All Nippon Airways and Japan Airlines.
The rail market is extremely competitive. We understand that some countries are interested in joining the TPP. They include Indonesia and territories like Taiwan and, possibly, China and India. So I think it's possible that this is becoming a model for trans-Pacific trade. We think that Canada cannot allow itself to be excluded from this group because of the potential it represents.
