I tend to disagree with the idea that it isn't necessary to broadcast the debate on television. I think that, in order for it to truly be a national debate, it has to be carried by CBC, Radio-Canada or some other major network.
We saw that with the Montreal mayoral debate I mentioned earlier. The leaders' debate was broadcast by the mainstream print media organizations: La Presse, the Métro newspaper, and Le Devoir. The event was much less popular and had much less of an impact because it was not broadcast by the major television networks.
Yes, it's important to appeal to younger Canadians who do not watch television, but not necessarily all Canadians are on Twitter or read the Huffington Post either. My view is that the debate should absolutely be broadcast on a wide scale, at least in the case of a national debate in both official languages.
