Thank you for your question.
In addition to the other areas that I have outlined, it's my understanding that in the Prime Minister's Office their vigilance with respect to costs would have included purchases big and small, although I don't know how big the purchases are there, in supplies such as paper, toners for photocopiers—goods and services. I think they were extra careful with that this year.
I think they were also careful to make sure that the decisions they made were cost-effective and to use the best practices that Public Works has promulgated in order to make sure that the taxpayer gets the best value for money.
