The specific example here is that during the passing of Bill S-4, the Railway Safety Act, we asked for the exemption to be 12 months instead of six months. That's simply because we operate in four seasons, and in order to introduce a new technology, we need to test it in all of those seasons before we can be certain it's going to be effective. We thought that was a relatively simple request to understand and implement, and it is important to our industry, yet we still are faced with the six-month exemption. That means it adds complexity and difficulty to anything we introduce if there's going to be a significant difference between the way that piece of equipment operates in the heat of the summer versus the cold of the winter.
