"OTTAWA — The average Canadian is in denial about the impact of air pollution on human health, assuming that it is either a long-term threat or a risk factor for vulnerable parts of the population, says a newly-released federal report.

The study, conducted for Health Canada by Environics Research Group, found that most Canadians acknowledge some health risks associated with poor air quality, but are divided on whether an advisory warning is a serious threat to all unless they have personally suffered from an illness such as asthma."
