Madam Chair, I guess I would respond by saying that the process is an established process within procurement, within the federal government, where the public works organization puts in place procurement vehicles for departments to use and, in particular, in telecommunications services. It's one that's had a well-established pedigree—for more than 40 years we've been doing this—so this is not new. This is something we continually do, it's been refreshed, and the method of supply, which is again optional by departments, is something that is at the preference of the departments.
There has been no direction from any policy or centre to make these services mandatory by departments and therefore it's difficult for us to put together a solid business case, not knowing what numbers might eventually appear. Not only that, it's also difficult, as I understand, for vendors to respond without knowing. So when we go out with a solicitation of interest we will provide parameters for the vendors to use, knowing what potential volume will be used through this particular vehicle, and they'll be able to price their products in that way. And departments, based on the prices that are provided, will be able to do their own business case to determine if that's the solution they're seeking.
