Sudden weather changes caused a 96-car pileup on a highway running through Toronto, Ontario, on Thursday morning. Only minor injuries were reported.

The enormous wreck happened at 9 a.m. Thursday morning and prompted the Ontario Provincial Police to shut down the highway for most of the day.

That stretch of Highway 400 services 80,000 vehicles a day, according to the Canadian Broadcasting Corp.

A number of highways and roads are closed around Toronto and its suburbs according to the Ontario Ministry of Transportation. The MOT has also advised commuters of multiple snow squall warnings around the province.

While a 96-car pileup is a very serious problem for everyone tasked with cleaning up such a massive accident -- not to mention for the drivers and passengers involved -- the Toronto mega-pileup is actually considered peanuts compared with some of the largest, most dangerous pileups in history.

The largest reported vehicle pileup took place in Finland in 2005. The more than 300 cars, three deaths and over 60 injuries confirmed make it one of the biggest multi-vehicle wrecks ever. That accident was caused by heavy snowfall and a bout of clear weather that gave drivers a false sense of security.

One of the most deadly confirmed pileups occurred outside Calhoun, Tenn. Ninety-nine vehicles were involved, between both south-bound and north-bound lanes. Twelve people died and 42 more were injured. The massive wreck got triggered when a tractor-trailer rear-ended another tractor-trailer in thick fog on one side of the highway, causing multiple cars and trucks to pile on to one another. Yet, on the other side of the highway, three cars started another chain-reaction of accidents.

In Japan in 2011, 14 supercars were involved in arguable the most expensive-per-vehicle crash ever. The total cost in damages was estimated to be around $4.3 million. Among the wrecked exotic vehicles in that accident were eight Ferraris and a Lamborghini.
