If I may, when departments come to meet, there are two questions you have to ask yourself. Do you control 100% of the message? If the answer is yes, you move on to the second question. Do you pay a third party or compensate a third party outside of the government to have that message broadcast or put on the air? If the answer is yes, that's advertising.
I'm going to give you a simple example. There's a huge billboard by Health Canada about quitting smoking. That huge billboard is placed at Place du Portage, just when you come up the Portage Bridge. That building is a Public Works building. That's not advertising, because they're not paying a third party to have it shown. For the same billboard placed on Highway 640 in Laval, you pay somebody for the same billboard, the same size, and the same colours—that's advertising.
