We certainly would--I don't know if the government would--but we're not necessarily in direct competition with them.
When I say we're in competition, there are instances where we have a private bus operator, say Coach Canada or Greyhound, on one side of the street, and directly across from them there is a public bus system. In Ontario, the GO system is right across the street from them. They're both selling exactly the same service--a bus travelling from community A to community B--but on one side of the street you pay tax and on the other you don't.
The other forms of transportation that you're mentioning, such as airlines, are not necessarily in the same business and competing the same way. I wouldn't want to address their level of taxation as to whether it's fair or not.
