Thank you, Madam Chair. Madam Chair, the department does look at a number of factors when looking at the type of office space we look at. In fact, the type of buildings we are involved in constructing through project management with other departments, the Canadian Building Incentive Program is one of those that we've endorsed and are using as we look at new facilities. The area of leasing office space and what's included in the waiting of those percentages, I'll ask Mr. Aumond to respond to that as he's much more familiar with the technical, I guess, discussion that would flow from this. Thank you.
