The number for the Transportation Safety Board is the amount to do the investigation. If you would like to find the measures, you'll have to look at Transport Canada estimates for the amount that will be added. They are taking some steps. I'm sure they're going to take many more steps as well as those around Lac-Mégantic. The safety board is an investigative body with a tiny budget. So for them, that amount of money just facilitated their investigation.
