MONTREAL - Canadian police said Wednesday that sudden whiteout conditions most likely triggered a massive pileup involving about 200 vehicles south of Montreal. 

There were no immediate reports of deaths, but Quebec provincial police said about a dozen people were sent to hospitals with minor to serious injuries after the midday crash in La Prairie, Quebec. 

Firefighters from La Prairie said two people were still trapped Wednesday afternoon, and authorities were trying to stabilize a diesel spill before extracting them from the wreckage. 

Those two people were considered to be in serious condition. 

The crash occurred around 12:30 p.m. on a stretch of Highway 15 that runs along the St. Lawrence River. The pileup of vehicles stretched for about a kilometer. 

Strong winds

Transport Minister Francois Bonnardel told reporters in Quebec City the pileup took place in an area where heavy winds come off the river, creating sudden blizzard-like conditions. 

``People were driving, there were strong winds ... and, suddenly, you couldn't see anything,'' Bonnardel said. ''And then, well, the pileup started.'' 

Two snow removal operations took place in the area in the hour before the incident, he noted. 

Bonnardel said the highway isn't known for particular safety issues and 65,000 vehicles use the southbound part of it daily. 

The transport minister said he'd await the results of an investigation before deciding if any measures needed to be taken. 

Dozens need towing

Police spokesman Sergeant Stephane Tremblay said about 50 vehicles were able to drive away from the collision, but 75 others would need to be towed. Numerous vehicles were mangled, including several large trucks. 

About 150 people were taken by bus to a nearby community center for treatment and to be picked up. 

Tremblay said police crash experts would study what caused the pileup. 

A school bus was also involved in the pileup, but none of the high school students on board were injured, said Andree Laforest, the province's acting public security minister.
