I have not heard that the TTC has even contemplated getting rid of all streetcars for several decades. Good though that they plan to buy more, they REALLY are needed as the King Project clearly shows that "If you put them into service (regularly), people will come."
A la King Pilot should be an example on why we should countine to keep streetcars. I really think DoFo hacked this person's Twitter, or told the dude what to say. I have never heard the TTC say this either.
