The Pan Am flame represents the history and spirit of the Games; it is a symbol that unites the 41 Pan American Sports Organization (PASO) member nations. The flame for the Pan Am Games was lit during a traditional ceremony at the Pyramid of the Sun, in Teotihuacan, Mexico. Following the lighting, the flame was handed over to a representative from the Host City. The flame was flown back to Canada to begin its nationwide journey before arriving in Toronto to light the cauldron at Opening Ceremony, which signifies the start of the 2015 Pan Am Games. The torch relay started in Canada on May 30, 2015, and will make its final stop on July 10, 2015, at the Opening Ceremony of the TORONTO 2015 Pan Am Games.
