Jan Gehl, the world's foremost city re-designer, gave an afternoon presentation, 2 weeks ago, in Toronto to an afternoon, standing room only crowd (500 people) at the Design Exchange. Jan gave his approval to the Design Exchange to put up the complete presentation for viewing online. Here's the URL for the presentation broken down into three parts: http://www.dx.org/index.cfm?id=6582
