I came across two publications this week that may help you if you have ancestors from Toronto, Ontario.
The first is...
Robertson's landmarks of Toronto: a collection of historical sketches of the old town of York from 1792 until 1833, and of Toronto from 1834 to 1893 : also, over three hundred engravings of old houses, familiar faces and historic places, with maps and schedules connected with the local history of York and Toronto - 1894
And while we are visiting Toronto, I also found this...
Assessment Roll for the Municipality of the City of Toronto 1890
It is formatted like a Street Directory, but gives the name of the occupant, name of the owner, the size of the lot and the value of the land and the buildings. In a few cases it also gives the occupant's income.
