Certainly when I have spoken to people, or when I have read literature from the period, Expo 67 figures prominently in people's recollection of the period. For some, 1967 is synonymous with centennial.
Having said that, it's a different time now, and I think it's important to recognize, or at least take into consideration, what Canadians may be prepared to entertain. I don't think we should necessarily read 1967 as a model that needs to be replicated hook, line, and sinker.
Having said that, it was an anchor event. It was something people could rally around. It was something that got global coverage and national coverage and local coverage. I think there was value, recognizing that we are in different times.
