It is a large area, it was either that or a residential complex. Lots of industrial land is reclaimed as industries are moved out of the city altogether. Having worked in Canada for a couple of decades in Lethbridge (railyards) I know what's in the soil, lol. Particularly in the area of the former roundhouse, but that is largely a shopping center now - ironically the almost exact spot is Kids R Us. The repurposed station for a health center is not that bad. Last thing that once happened there was a large derailment (also involved tank cars) just past where the building is - for which I was responsible, in a way, since I was the switch-foreman that night. Long story ......
