Okay. I'll move pretty quickly.
I represent a riding called Mississauga—Streetsville, which on your map is Highway 40 at Meadowvale and 45 and 48 near Streetsville, so this is definitely a concern to my residents.
We have Hamilton, which is underutilized; Pickering is a bit farther outside the GTA, but we have a lot of land just north of the 407 and the escarpment, and Metrolinx has preliminary plans to get more rail out that way.
Is there a conversation that should be had about whether an airport can go up past the escarpment, up north there?
I'll start with you, Peter.
