The flame was lit on Monday at the Pyramid of the Sun in Teotihuacan, Mexico by the Aztec people.
CBC Sports Weekend host Scott Russell was in Mexico reporting on the route the torch will take as it makes its way north.
The torch will now be transported to Toronto and delivered to David Peterson, chair of the Toronto 2015 Pan American Games organizing committee.
The 41-day relay will then begin in Toronto this Saturday, where 3,000 runners will cover 20,000 kilometres (15,000 by air, 5,000 on the road). It concludes with the lighting of the cauldron at the opening ceremony on July 10.
The torchbearers include retired Canadian astronaut Chris Hadfield, world figure skating champion Patrick Chan, two-time Olympic champion Alexandre Bilodeau, and two-time Olympic medallist Simon Whitfield.
