This week on City Space, our team attempts to unravel a few puzzling urban enigmas. Can anything be a street name? Does a patch of grass qualify as a park? What does this unique house reveal about the development of the area? Irene and our producers guide you through different neighborhoods as they try to solve the mini-mysteries that define a city - in this case, Toronto. The hows and whys (or why nots) of urban design and city planning.
