Thought this was kind of interesting - a map of Toronto's streets in 1908, colour coded by type of street paving.
It also suggests how built up the different parts of the city would have been then. While there were streets already being laid out as far as Etobicoke, they still would have been fairly rural as indicated by the unpaved roads. Asphalt paved areas on the other hand would have likely represented the most built up areas. The population of the city would have been about 300,000 at that time (the population within the developed area there today would be around 500,000 by comparison).
