Grass has massive advantages in its availability and familiarity to those maintaining it. Any other plant choice is looking at both availability and expertise issues, which will affect cost. That said, if it can be offset by less maintenance, it could work out.

I'd prefer a native planting over grass, certainly, but I also prefer grass over bare concrete.

I mean, if they're installing a mechanical irrigation system and are going to require regular maintenance, than pretty much any set it and forget it plant is going to beat it on price, no matter how expensive it is to put in at the beginning. I think the fact that your point probably carries weight with metrolinx just shows how absolutely terrified of risk all our large organizations are.

But I fully agree with the final sentiment.
