Montreal's World Fair, Expo 67, closes with over 50 million visitors.

Montreal is the largest city in the province of Quebec, the second-largest in Canada, and the ninth-largest in North America. It was founded in 1642 as Ville-Marie, or "City of Mary", and is now named after Mount Royal, the triple-peaked mountain around which the early settlement was built. The city is centred on the Island of Montreal and a few, much smaller, peripheral islands, the largest of which is Île Bizard. The city is 196 km (122 mi) east of the national capital, Ottawa, and 258 km (160 mi) southwest of the provincial capital, Quebec City.

The 1967 International and Universal Exposition, commonly known as Expo 67, was a general exhibition from April 28 to October 29, 1967. It was a category one world's fair held in Montreal, Quebec, Canada. It is considered to be one of the most successful World's Fairs of the 20th century with the most attendees to that date and 62 nations participating. It also set the single-day attendance record for a world's fair, with 569,500 visitors on its third day.

October 29 is the 302nd day of the year in the Gregorian calendar; 63 days remain until the end of the year.
