anniversary of 9/11, President Barack Obama recalled Canada's help on that day, and expressed his gratitude for Canada's friendship and solidarity. Aftermath Totals The actual number of diverted aircraft and passengers varies from each source. Transport Canada said over 33,000 passengers on 224 flights arrived in Canada, whereas Nav Canada gave a total of 239 flights. According to Prime Minister Jean Chrétien, the number of flights was between 225 and 250 and the number of passengers was between 30,000 and 45,000. Halifax International Airport received the most flights while Vancouver International Airport received the most passengers. Transport Canada and airports involved in the operation also reported a dramatic increase in traffic at their websites for updated and current information concerning news releases, FAQs, and diverted flight information. Transport Canada reported that on September 12, 2001, the day after the attacks, there were more than 47,000 visits to their web site alone. Halifax International Airport reported that just in September, there were 2.1 million visits to their web site, and in October, half a million. Both numbers were far above the average at the time of 40,000 to 50,000 visits per month. Consequences for Canada After the initial task of diverting the flights was over, thousands of stranded passengers and flight crews had to be housed and fed until the crisis was over. During the diversion of flights, some airports, including Vancouver International, were inundated with hundreds of telephone calls from members of the public and the corporate community offering their support. In Ottawa, SitCen staff were also inundated with calls from airports, air carriers, the media, and the general public. SitCen staff received an estimated 5,000 calls a day. When asked in a CNN interview if he was able to get food to the passengers, Jean Chrétien, the Prime Minister of Canada, said that he was able to, and that "many of them have been accommodated in hotels and schools and gymnasiums and so on. And the Canadian authorities and provincial authorities are working… [to make their visitors] in those places as comfortable as possible." Public efforts to help those affected by Operation Yellow Ribbon led to positive remarks on the subject by people such as Chrétien and his wife, Aline; the United States Ambassador to Canada, Paul Cellucci; Collenette; Governor General Adrienne Clarkson and her husband, John Ralston Saul; and in the provinces, premiers, and lieutenant governors.
