Public Works is responsible for contracting. Privy Council Office has a broad responsibility for coordinating, including coordination of economic advertising.
I will try to respond to several of your questions.
In terms of costs, last year $49 million was spent on advertising related to the economic action plan. This year about $24 million is appropriated for the last portion of the economic action plan ads. Those include advertisements for economic action plan programs from the Department of Finance and from the Department of Human Resources, and for Canada Revenue Agency ads on tax filing that encourage Canadians to take advantage of the tax benefits and tax deductions that are available to them.
The government's position has been that in the face of historic economic crisis, Canadians needed to know what was being done and what programs and services were available to them, and those programs continue to be available to them.
