Articles on Toronto and an index article for the List of neighbourhoods in Toronto partially exist. Is it right to call them "boroughs"? Only five (East York, York, North York, Etobicoke, Scarborough) were known by that name (all but East York were promoted to 'City' before amalgamation). Boroughs were invented for Ontario to act like New York boroughs: municipalities in a Metropolis with the exception of the main municipality, which remained a city (City of Toronto). With Toronto losing a level of government in the 1998 amalgamation, all this disappeared.
There should be an article on all six Toronto historical cities, using the borough's official name (usually "City of X, Toronto") with no mention of Ontario (as these cities are no longer legally recognized by Ontario, "East York, Ontario" simply does not exist). Each such city article should have a list of localities within that city at its end, using the naming conventions above.
Every locality needs at least a 500-character (excluding formatting) stub article, built on top of its framework article. See the list of geographical stub articles.
All areas of historic importance need substantial articles.
Every Toronto subway line should have an article of the same level of quality of the East London Line article for example, but the list of stations should be the same quality as the London Central Station (though a red link). Do not waste energy on this topic that should be saved for other issues, e.g. water and power systems, that are less visible but are actually more interesting.
