This is exactly what the guidelines are about and communities that are doing it properly are having those conversations. When we first produced the guidelines in 2003, it assumed that all the development was happening in a greenfield setting. Where you can do a setback and a berm, then it's great, but the challenge is really in an urban core. What do you do when Montreal or Toronto or somewhere else wants to develop their urban core? That's reasonable, but you have to mitigate it, and the cost has to be on the developer and you have to have that conversation at the front end.
The challenge we have at FCM is we don't have jurisdiction over land use. I know it's very frustrating for the federal railways and it's a constant thing. These are provincial decisions, but we certainly are providing as much guidance as we can.
