If I may, I'll elaborate, because it's very confusing. There are always different numbers being presented on advertising and picked up in the media from supplementary estimates and the annual report.
Basically, as Mr. Matthews said, there are two fundamental ways to fund advertising. One is through the government advertising plan, and that is reviewed by cabinet annually to address new government priorities each fiscal year. You see those in-year requests through supplementary estimates. Departments and agencies prepare proposals for review for Privy Council. They're challenged, and they're approved at that level. Then submissions go to the board. The board approves them, and they ultimately get reflected in your estimates process.
The second route is that departments can fund some advertising from their internal reference levels. You often see that in the reports on plans and priorities.
Where do you see the bigger picture as opposed to just what's in-year? Treasury Board Secretariat posts on its website a quarterly posting of all the things that have gone to the board that have been approved. Those would be any of the advertising initiatives pursuant to the government advertising plan that have the policy approval and have gone through the submission challenge process. They're posted there quarterly as they are approved and also for multi-year. As a result, the numbers on that posting are different from what you see here, because you're only seeing this year's spending in the supplementary estimates.
On the quarterly, you will see decisions made last year that have implications for this year as well. We also show when something has been taken away, so there are reductions as well.
If you want to know everything with regard to advertising, the best place is Public Works. They do a regular annual report that captures all of the government advertising.
