Hooray! Metrolinx, the regional transportation agency here in Toronto actually used a map I made back in 2012 in a report which I came across through a friend. The map displayed the density of intersections in the Toronto region, and highlights some of the more industrial locations throughout. The heading photo used by Metrolinx highlights the Pearson Eco-Zone, an enormous industrial part surrounding Pearson International Airport (the big white splotch in the image above).
