Latest On Northwestern Ontario Derailment

Investigators are back at the site of this weeks train derailment near White River.
Rob Johnston is leading a team of government safety inspectors who are trying to figure out what happened to throw 22 Canadian Pacific freight cars off the track.
Johnston says officials have secured some wheels and rail and they will be sent to a lab in Ottawa for analysis.
He says it’s early in the investigation and it will likely take several weeks before the cause is known.
CP says while it initially thought only four barrels of oil escaped the toppled cars, it appears about 400 barrels broke free.
Spokesperson Ed Greenberg says crews quickly contained a leak in one of the cars but didn’t realize the other had spilled until late Wednesday.
Greenberg says the spill was initially hidden under the snow and migrated “a short distance” beneath it.
He says CP has built a berm and taken other steps to contain the leak, and all the oil will be removed during the cleanup.
