I think it comes down to the fact that this is something which the federal government made a commitment to do 20 years ago. It's dealing with looking at the way that policy proposals, legislative proposals, and program initiatives might affect men differently than women. That can help departments change how they're going to deliver a certain program to make sure that they're considering those effects on the different stakeholders. It's important from the point of view of that consideration. It's also important from the point of view that it's something that the government committed to do internationally.
