I think I have about a minute left. Mayor Vodanovic, just quickly, if you can, you talked about putting a price on things and the importance of doing that. I think you mentioned a levy or some sort of deposit or additional fee, whatever you want to call it, in terms of incenting behaviour or asking people to change their behaviour.
I think a great example of that is a price on pollution, like what Canada is trying to do in terms of putting a price on pollution to get us to reduce our emissions. Would you agree that it's a good example of that, an effective example of that?
