Book excerpt: Unbuilt Toronto explores the failed architectural dreams of Toronto. Delving into unfulfilled & largely forgotten visions for grand public buildings, landmark skyscrapers, roads & highways, transit systems, & sports & recreation venues, the authors outline such ambitious but ultimately unrealised schemes as St. Alban's Cathedral, the "Newark 2011" subway system, & a 1911 city plan that would have resulted in a Paris-by-the-Lake. Readers will lament the loss of some projects (such as the planned construction boom for the Olympics), be thankful for the loss of others ("City Hall was supposed to look like that?!?"), & marvel at the downtown that could have been (with underground roads & walkways in the sky). With an eye on the future as well as the past, the author takes stock of Toronto's status quo in 2008 & offers some bold predictions on the city's architectural future.
