Mr. Speaker, let me thank my hon. friend and colleague for raising that question.
The number one culprit, when we speak of air pollution in our cities, is caused by car emissions. That is why the government has announced, starting with next year's car models, that the standard emissions in Canada will be the tightest anywhere in the world.
Along with the new generation of car emission standards, we need to usher in a new generation of cleaner fuels. That is why the government has moved boldly on MMT, on benzene and on sulphur.
When the cars hit the road, that is provincial jurisdiction. Older cars pollute 10 times more than new cars. That is why the province of Ontario, for instance, should stop paying lip service to this issue and begin to walk the talk by putting an inspection and maintenance program for cars in place so that all of us can breathe a sigh of relief.
