So you think you know the history of Toronto's water? Taddle Creek used to flow down Philosopher's Walk, Garrison Creek used to flow through Trinity Bellwoods Park, all of the land below Front Street used to be in the lake, and R.C. Harris built everything; what else is there to know? Well, how about the mighty Laurentian River that flows from Georgian Bay to Lake Ontario right through High Park? That's just one of the surprises exposed by HTO: Toronto’s Water from Lake Iroquois to Lost Rivers to Low-flow Toilets published late last year by Coach House Books. The book's two-and-a-half dozen essays and accompanying photos document our changing relationships through time with the natural and artificial watercourses that flow through the city.
