In early 2003, Toronto was affected by the SARS epidemic. Although the disease was primarily confined to hospitals and health-care workers, tourism in Toronto suffered significantly because of media reports. To help recover the losses the city suffered in industries and tourism, the city held the SARS Benefit Concert (colloquially termed "SARSStock"), which attracted 450,000 people in late July, making it one of the ten largest concerts in history. Two weeks later, the city was also affected by the 2003 North America blackout. In the resulting chaos, the city ground to a halt, with people taking to the streets to party and talk to their neighbours. Power was not restored for more than 12 hours; in some isolated pockets, not for up to three days.
