Facilities were so crowded that many even had to wait on the tarmac.\nSmall town airports in Canada were suddenly host to thousands of terrified, hungry, and exhausted passengers.\nGander, Newfoundland saw its population increase by almost 70%. There, Canadians housed displaced Americans in their own homes.\nThankful Americans later created a scholarship fund for Gander students that gathered over one million dollars.\nAcross the country, countless Canadians volunteered to help American families. Donations of food and supplies came by the truck-load. Pharmacies filled prescriptions for free.\nAccording to History.ca, then-prime minister of Canada Jean Crétien described the United States and Canada as "people united in outrage, in grief, in compassion, and in resolve...a people who, as a result of the atrocity committed against the United States on September 11, 2001, feel not only like neighbours but like family."\nIn all, about 240 diverted planes landed in Canada carrying about 33,000 people.\nThe truth is that while we may have temporarily forgotten the neighbourly cooperation that united Canada and the U.S. on that day, that same spirit has not disappeared.\nCanada would do it all again. The people of the United States would, too.\nTo honour the people who lost their lives on 9/11 and the Canadians who stepped up to help, we must always remember that the friendship between the two counties will outlive presidents and prime ministers.\nSource 1 | Source 2\nEditor's note: This article originally featured a cover image mistakenly labelled as a photo from Gander on September 11th.
