Okay, I'll just move on, then.
We do know that transporting goods such as oil is much safer by pipeline than it is by rail. It is also more environmentally friendly. At the same time, we are continuing to increase our transport of oil by rail. In the last 10 years it has almost doubled, which I don't understand.
I guess I would address my questions to Mr. Keenan.
In the text of your statement, Mr. Keenan, you mentioned that Transport Canada has “also amended regulations to impose stricter requirements on the securement of unattended trains”. My thought here is: Why do we have unattended trains carrying dangerous goods? How frequently do unattended trains carry dangerous goods?
