Montreal 1976
1
The first Olympic games held in Canada gave every other city in the country a hard on to hold their own.
Its hard to see why, since the games saddled the city with a debt that took 30 years to retire, and provided little in the way of infrastructure, except for a massive stadium with a retractable roof that didn't work.
On top of that, the host country came up empty in the Gold medal column, the only time that has happened in the history of the Summer Games.
