Toronto's top public health official said Monday the city is preparing a massive H1N1 immunization plan, even though the second wave of the virus may not be as bad as predicted.

Dr. David McKeown, Toronto's medical officer of health, said there have been 45 reported cases of H1N1 in Toronto since the beginning of September.

Nine people have been hospitalized, but nobody has died from the virus in Toronto.

McKeown said he's encouraged by what he's seen in other countries. "What they saw was a flu season which was only a little worse than normal," he said.

"In terms of the overall impact on the health of the population and our healthcare system, it has not been the really bad pandemic that we've all been planning for," McKeown said.

Nevertheless, the city is preparing an "unprecedented" immunization plan, he said.

The city plans to open 10 clinics across the city to distribute the vaccine. The tentative start date for public H1N1 vaccine clinics is the first week of November, and the clinics are expected to stay open for six weeks.

The city hopes close to a million people will receive the shot.
