I'm kind of interested, did the shed get grandfathered into the fire code? I don't have any expertise on this hence why I ask. Even TTC subway stations are being mandated to be upgraded to meet modern day fire codes.
If there is one thing I can say, it will probably take a disaster for parties involved to learn that the shed should've been torn down or have a small segment salvaged for museum preservation. On this note and related to wasting money on this shed, I did read somewhere that Metrolinx is now toying with the idea of reducing the number of tracks and expanding the platform width to facilitate the RER system...I wonder how much more money it will take before they decide to start with a clean slate.
