No, this definition was not explicitly included. We are using a much shorter format in this case. We're simply talking about national security, as in the Immigration and Refugee Protection Act, for example. The expression “national security” will therefore be interpreted based on the facts and context. In this case, we're talking about passports. Therefore, there must be a link with the use of a passport in order to talk about national security.
I think that some parts of the definition of Bill C-51 would not apply to the use of a passport. However, we can't rule out the possibility that the definition influences how we interpret national security in certain contexts. In the context of past legislation, the courts have found the use of the simple expression “national security” to be reasonable. In fact, they acknowledge that this concept is fluid and truly depends on the context.
