About 6,600 athletes from 41 countries will compete in 36 Pan Am sports — including 28 Olympic sports — plus 15 Parapan Am sports.
Canada is fielding its largest-ever Pan Am Games team of 700 athletes, and has set a goal of finishing second in the medals — behind perennial champion U.S. — with 160.
The Pan Ams will run July 10-26, while the Parapan Am Games are Aug. 7-14.
The sale of about 1.4 million tickets is expected to bring in roughly $40 million, with sponsorships and government subsidies helping cover the rest of the Games' $2.5-billion price tag.
Organizers predict the international competition will draw 250,000 visitors from outside Ontario, while the rest will likely be local.
