It varies. I don't know what other departments do. I know what is done in ours.
Advertising is released in a number of ways. There's an annual report to Parliament; everything is there. We disclose our own numbers year-end as well.
Normally there is a period of time after the end of the campaign when adjustments can be made to the account, and that period is 90 days. So strictly speaking, according to our contracts that Public Works and Government Services administers--and they handle all the ad placement--the final numbers would be available 90 days after the end of the campaign.
Frankly, I thought we were rather responsive in waiting to the end of the campaign to get pretty reasonably accurate numbers, certainly much more accurate than would have been available to us prior to that, and to do that within three weeks.
