I want to make sure that I'm actually answering your question.
It has to meet the standards of the national emergency. The consequences have to be so severe that the welfare of the country as a whole is affected. However, that does not mean that an emergency has to take place in all regions of the country.
In the case of the October 1970 crisis, the crisis was essentially limited to Quebec, yet the civil liberties of Canadians right across the country were suspended. Censorship was used in Guelph, Ontario, with the University of Guelph student newspaper. In Vancouver, there was a threat to use the act, as well, although it was not necessary to have it there.
We wanted to have legislation that would allow the government to say, “There's a grave crisis here. It meets the definition of a national emergency, but we aren't going to suspend everybody's rights; we're going to target it.”
