creation in 1999 the Ontario Medical Association and the Canadian Medical Association have each released estimates of the number of illnesses caused by air pollution in Ontario. The Ontario Medical Association estimated in 2005 that total air pollution (from all sources) would cause some 5,800 deaths and 17,000 hospital admissions that year. It also estimated that the direct health care costs of air pollution in Ontario were about $507 million, and the total economic cost of air pollution to be about $7.8 billion. However, three years later the Canadian Medical Association released a report that estimated that in 2008 there would be 4,597 hospital admissions in Ontario caused by air pollution, of which around 1,178 would result in acute premature death. It also suggested that in the year 2031 there would be 2,222 deaths in Ontario caused by air pollution, compared to 7,774 hospital admissions. In addition, the number of smog advisory days in Ontario peaked in 2005 at 53 days. In 2013, there were only two smog advisory days in Ontario. In addition, there were no smog days reported in 2015, according to a report by Air Quality Ontario In late 2004, Norm Sterling, who was the Environment Minister in the Progressive Conservative premier Mike Harris's cabinet, stated that Drive Clean had already had its greatest impact on air pollution and had served its purpose. Sterling is often referred to as the founder of Drive Clean. Drive Clean can only address a small fraction of the total automobile emissions problem, because all internal combustion vehicles burn fuels which ultimately pollute the air (including most so-called "alternative" fuels). The Greenpeace co-founder, Robert Hunter, wrote in 1999 that Drive Clean "has turned out to be an agonizing bureaucratic nightmare that hits drivers with what is basically another tax and a huge hassle, while accomplishing -- in Environmental Commissioner Eva Ligeti's assessment -- 'minimal benefits.'" Critics of Drive Clean, who included Hunter and many other environmentalists argue that a greater long-term impact on overall air quality would result from reinvesting the same provincial resources towards encouraging low-emitter technologies, some of which offer electric power as an alternative to 100% internal combustion propulsion. There has been a call for the Ontario government to admit to Drive Clean's minimal impact, and to begin promoting low-emissions vehicles such as hybrid cars, plug-in hybrid electric vehicles, zero-emission vehicles such as the ill-fated General Motors EV1, and
