How much is life being affected in Toronto? I have friends on the Village Harmony tour that is due to be in Toronto on Thursday & Friday. Are people avoiding public gatherings like concerts, etc?

To keep all this in perspective, according to the CDC:
Each flu season is unique, but it is estimated that approximately 10% to 20% of U.S. residents get the flu, and an average of 114,000 persons are hospitalized for flu-related complications. About 36,000 Americans die on average per year from the complications of flu.
