In light of the recent announcement regarding the Scarborough subway, I thought I'd share my map of Toronto's future Subway/LRT system to help provide an overview of what's going on in Toronto.
The extension of the western portion of the Yonge-University-Spadina Line (yellow) from Sheppard West to Vaughan Centre is well under construction and will be open in 2016.
The Eglinton Crosstown (blue) is also under construction, however they just started boring the tunnels. We're looking at completion around 2020.
The extension of the Bloor-Danforth Line (green) from Kennedy to McCowan was the subject of the recent announcement. The alignment shown here is what the city, the TTC and the Feds prefer, whereas the province prefers one less station and a slightly different alignment. Regardless of which way they ultimately go, the funding is now secure.
The Sheppard East LRT (orange) and Finch West LRT (grey) have both been approved and funded. I haven't included station names because they haven't been determined yet. There is fear among proponents of the Sheppard East LRT that the funding reserved for it will be shifted to other projects, as Mayor Ford opposes the line. He'd rather see the extension of the Sheppard Line (purple) east.
The Wellington-Front Line, as I call it, aka the Downtown Relief Line (red), is the only line on this map that is hypothetical and unfunded, but it gives a sense of the kind of line that will eventually be proposed. According to the TTC and the provincial transportation agency, it's the next priority after the already planned lines.
After that, we can probably expect to see an extension of the eastern portion of the Yonge-University-Spadina Line (yellow) north to Richmond Hill, an extension of the Sheppard Line (purple) west to connect with the western portion of the Yonge-University-Spadina Line, an extension of the Eglinton Crosstown (blue) west to Pearson Airport, and an extension of the Downtown Relief Line north to the Eglinton Crosstown. I haven't included these extensions in this map, as they are a ways off at the moment.
