This is not so much a fantasy map as a "what could have been" map, but it fits the general idea of the thread. A few days ago, I was sitting in my chair and I thought "Huh, I wonder what Toronto would look like if the 1912 rapid transit referendum had passed." After a few days of tinkering in mspaint and reading up on history, this is the result: a map of TTC service in an alternate 1932 (based on a map from Mike's Transit Stop).
The construction was delayed for several years by the outbreak of World War One, allowing for some revision to the plans, especially in regards to station spacing, which was greatly reduced over the original concept. Shovels were in the ground for the Yonge Subway before the end of the war, and it opened in 1921, followed by streetcar-subways along Queen and Bloor during the economic boom of the 1920s. Now, in the wake of the stock market crash, the TTC's future expansion is in doubt for the time being. Major butterflies include a Leaside streetcar, Rogers Road, Oakwood, and Weston streetcars that go to the subway (with the first partially replacing the Davenport streetcar), retained streetcar service to Lambton and Islington (with Dundas cut back to Bloor), an extended and separate Lansdowne streetcar service, the replacement of the Dupont streetcar with the Bay streetcar, extended Dufferin and Parliament streetcars, and some alternate bus routings in the north.
Yonge stations, north to south: St. Clair, Shaftesbury, Crescent, Bloor, Wellesley, Carlton, Dundas, Queen, King, Union.
Queen stations, west to east: Roncesvalles, Lansdowne, Dufferin, Dovercourt, Ossington, Trinity Park, Bathurst, Spadina, John, University, City Hall, Yonge, Church, Sherbourne, Parliament, Sumach, Broadview, Carlaw.
Bloor stations, west to east: Roncesvalles, Lansdowne, Dufferin, Dovercourt, Ossington, Christie, Bathurst, Spadina, Avenue, Bay, Yonge, Sherbourne, Broadview
It is not clear from the map, but the lines entering the Queen subway terminate at the end of the subway section. Lakeshore runs to Carlaw, Queen and Beach to Roncesvalles.
