The 1976 Olympic Games were opened in a stadium that had not been completed.

Construction problems with a leaning tower, designed to move a retractable roof, were not sorted until a decade after the Olympics left Montreal and the rising cost of the build meant the city only finished paying for the stadium, dubbed the 'Big Owe' in 2006.

The Olympic flame arrived on time, though, after being transformed into a radio signal and sent from Athens to Canada by satellite. A receiver used the stored energy to activate a laser beam which re-lit the torch.

It was then carried by foot from Ottawa to Montreal in more traditional fashion.
