That's not how it works. If the land is contaminated, then they're not allowed to do any development on the land until it's remediated. The City of Vancouver would know if any of the Arbutus Corridor were contaminated and would not allow the land to be developed in any way before doing remediation.
It's like
abandoned gas stations -- if you want to change the use of the land, say from rail to multi-use, then if it's contaminated you need to remove the contamination. You can't just pave it over, use it, and wing it later.
That link has an interesting tidbit: the contamination can't be sold, so since the rail company initially owned the land and then sold it, they'd be responsible for the removal of the contamination even after the land was sold. There's been absolutely no talk about this anywhere that I've seen, and the City of Vancouver would most certainly raise a stink about it should they know any of the land is contaminated.
