Toronto’s IdeaCity conference, which gets underway this weekend, is an intellectual celebration without direction, and that’s exactly how organizers want it. The hope is that, by bringing together some of Canada’s greatest thinkers for the mental equivalent of a jam session, great ideas will emerge, and walling in such broad-minded folks with a single ‘theme’ would seem to be antithetical to the effort. “But the event is still trying to find its feet conceptually. Some of the participants are genuinely ‘ideas’ people, but others are pop singers and wilderness adventurers.”
