As I mentioned earlier, I want to clarify one point. This is in the current national transportation policy statement, which is found in the current section 5 of the Canada Transportation Act, and “only if necessary” has not been interpreted as fettering the minister's discretion to regulation.
Quite the opposite, this section has been used to support the fact that when a section is enacted in the statute or any other statute to which this policy relates, it's a recognition or a statement by the government that the market has not prevailed and regulation has become necessary. So it's been used as an assistant to interpret the provision, that the intention behind the provision was to supply what the market forces were not able to supply. That's how this provision has been interpreted in the past.
