No, I'm not aware of that study. I can only tell you that 38 airports are identified. At least nine airports have traffic greater than one million passengers and bilingual services are required there. In the other cases, these are airports where there's less passenger traffic but where the offer of bilingual service is equal to or greater than 5%. I couldn't tell you where that study comes from or what the findings were, but I know that we have 38 airports designated under the Official Languages Act.
