It then goes on to say, at new section 9B(2), "However, a method that would otherwise be a building method under subsection (1)(a) is not a building method if it is declared by the Governor-General by Order in Council not to be a building method." So it seems that a building method is putting one or more things together, and if it's not, the Governor-General can say that it is. But if it is, the Governor-General can say that it's not, but it's not clear why the Governor-General would say that or on what grounds they would use, other than the law that people can actually read before them.
