Dr. Barbara Yaffe, Toronto's Acting Medical Officer of Health, has released a study estimating that five common air pollutants contribute to about 1,700 premature deaths and 6,000 hospital admissions in Toronto each year.

The report cites studies around the world demonstrating that air pollution causes reduced lung function, asthma attacks, emergency room visits, lung cancer, high blood pressure and reduced life expectancy.

The report and related materials are available on the City of Toronto website.
