It was drawn on the map for the Big Move report. It's location hasn't been chosen yet. Presumably it will be on the map at the upcoming public meetings for that project; though likely just a shaded corridor.
The Big Move is largely a collection of City/Regional Gov't plans that have been thrown into a single, over-arching plan. Metrolinx has had very little to do with any of the transit planning inside of the City of Toronto, except for providing funding for it.
I don't see why you are obsessing on this issue. It's seems like a very minor detail in the whole scheme of things. The DRL project has been going ahead since about May, with very little interest from the media, despite numerous press releases and comments from Giambrone.
How is the single most important piece of transit infrastructure needed in this city a "minor detail"?
Since when does media attention = importance? There are plenty of very important issues that the media completely ignores. People would rather hear about Lindsay Lohan's jail time than genocides occuring right now. That pretty much sums up the media's ability to properly gauge the importance of issues.
Would you prefer that they just drop the plan?
No, I would have preferred that the DRL was included in Transit City from the beginning, or at the very least added when Metrolinx started showing interest. It was placed in the 25 year portion of the Big Move because the TTC didn't see it as a priority. Had the TTC had it at the top of their to-do list when Transit City was first announced, I'm pretty sure it would have been near the top of Metrolinx's to-do list as well.
