It's something we're actively reviewing. I believe that our concern is the unintended consequence associated with that component.
We run commuter rail, for instance, and from that standpoint, it's one of the bigger concerns that exist in the event of a labour outage. Again, we are reviewing it, but we are concerned about the unintended consequences.
Mr. Chair, if there is more that is required, I'm happy to take to come back to the committee on this subject.
