Looks like it is in the ravine at the end of the runway on the south side of the airport (the runway that is aligned northeast to southwest). Can see it here on Google maps, enter 'Toronto, CA' move a few miles west of downtown to the large airport, then switch to the satellite aerial photo:

Don't see people mulling about in the grassy areas, a sizable creek surrounds the other sides, suggesting that few made it off the plane.
Hopefully I'm wrong on that, and the following, but it sure has taken a long time for any of the firetrucks gathered around the edge of the runway to get moving down off the pavement and to where they could get water on the fire. Do they not drill for a plane sliding off the runway? I'm not a fire expert, but the response appears to have been slow, timid, and inadequate.
