What are the other possible locations?
For just 2 trainsets (or has it now bloated to 3). Lakeshore East width is good for 6 tracks; but with 2 lost from the Don to Pape, for the Ontario Line, park some trainsets between Pape and Coxwell, along new track there. Or east of Danforth GO, where there's not any environmental concerns.
An abandoned rail line near Union? Sounds like a jackpot to me...
For just parking a train or two perhaps. But the amount of other infrastructure that's too be built in an environmentally sensitive area - which seems to keep increasing - is the issue. It also makes future use of that track (which hasn't been legally abandoned) very difficult.
Also problematic was the lack of a process about the selection of this site. The first time anyone heard that such a proposal for additional storage was on the table, was in a public meeting about the future additional city GO stations, and this plan just appeared there out of nowhere - completely skipping the site selection phase.
The lack of transparency and public communication at Metrolinx is stunning.
