Thank you. Your question gives me an opportunity to specify what my role is, as you requested, and to clarify some percentages. Our Bloc Québécois colleague mentioned 60% and 40%. I would like to clarify that. The 100% policy applies to foreign manufacturers. When a contract of that kind is signed, 100% of the money you receive over the course of that contract must be reinvested in Canada in the form of industrial benefits.
In my opening statement, I quoted percentages, including 50%, 30% and 15%. I would like to explain what they mean. Fifty percent is the minimum economic benefits for the aerospace and defence sector. Thirty percent is the minimum in economic benefits for key technologies as I pointed out in my opening statement. Nine-key technology areas were identified, for the first time, through analyses undertaken with the aerospace industry. Officials from my department met with aerospace industry officials in order to determine what the key technologies of the future would be in the aerospace and defence sector, technologies that were the most important for the development of that sector. Together, they drew up a list of nine-key technologies. Thus, 30% of the contracts must be in those key technology sectors and 15% must go to small- and medium-sized businesses. It's important to understand that these are not exclusive percentages.Therefore, a contract between Boeing and a company might fall under the 50% category because it's in the aerospace and defence sector. It might also fall under the 30% category because it deals with a key technology and finally, it might fall under the 15% category because it's with a small business. The percentage categories are not mutually exclusive.
That said, it's important to understand something about the 60%, that we talked about during our press conference with Boeing. Before the contract was signed, 60%—that is, $577 million—of an $869 million contract was identified in industrial benefits for Canada, that meet the criteria. As I stated during the press conference, and as I am repeating it now, Boeing will be announcing those contracts over the next few months.
I'd like to take the opportunity to clarify some figures. We announced the acquisition of four C-17 aircraft, totalling $3.4 billion. How is that $3.4 billion spread around? An amount of $1,8 billion goes to aircraft acquisition, including $869 million for the purchase of the Boeing aircraft. There will be $869 million in economic benefits—one dollar for every dollar—because the purchase involves a foreign manufacturer.
Also $660 million will go to National Defence infrastructure development and to various projects National Defence manages. This involves items such as the construction of hangars for the airplanes. That money is spent directly in Canada, and therefore the policy does not apply.
The third part of this $1.8 billion is $271 million that will go to the purchase, from the American armed forces, of equipment to support these aircraft. As you know, the policy does not apply to the $271 million because this is a government-to-government purchase. The policy only applies if the purchase is from a foreign manufacturer. One portion of that $271 million will go to engines. Under this contract, the American armed forces will work with Pratt & Whitney to make sure that the aircraft have the necessary engines. The dollar-for-dollar policy applies to that portion. There will therefore be 100% in economic benefits for the acquisition of aircraft and engines and we will be receiving more than $1 billion in benefits.
Furthermore, the overall amount of $3.4 billion includes another $1.6 billion. That will be spent on services from the Canadian armed forces to pilot training. Out of that $1.6 billion, $900 million will go to Boeing in its contracts with the American armed forces for aircraft maintenance. Our policy applies to that $900 million.
That is why I can tell you that the $3.4 billion contract for the four C-17 aircraft will result in a minimum of $1.9 million in economic benefits, as well as $660 million in direct purchases in Canada. I think it's important to give you that context and I thank you for giving me an opportunity to do so through your question.
