A 57-year-old Quebec woman has died after being hit by a snowblower in Trois-Rivières.

The woman was struck down Tuesday while walking in the middle of a half-cleared road where a private contractor was driving his snowblower tractor en route to another job, Trois-Rivières police said.

The driver told authorities he never saw the woman and thought he had hit a garbage can, police spokesman Michel Letarte said.

"He was really shocked about it,"Letarte told CBC News on Wednesday. "He stopped right away after [realizing] he hit a person."

The woman's name hasn't been released to the public.

The Quebec coroner will perform an autopsy to determine the circumstances and cause of death, but visibilitywas likely a contributing factor, Letarte said. "You know, with all this accumulation of snow, people have to take care when they are walking in the street right now."

The Trois-Rivières death is the second snow-related fatality in Quebec this week. A 7-year old girl died in Lévis on Monday after suffocating in a snowbank.

Snow causes headaches for Montreal drivers

Getting around Montreal was still difficult Wednesday as the city continued to remove the snow that fell on the weekend.

Despite earlier calls from city officials asking drivers to move their cars, snow removal crews say their work is being delayed because people are ignoring "no parking" signs and not moving their vehicles.

Some residentshave complained about a lack of co-ordination among city and borough snow-removal crews, who normally try towork together to clean the same side of a street if it falls under both municipal jurisdictions, as is the case for PapineauSt. or Henri-Bourassa Blvd., for example.

It has beenhard toco-ordinate allsnow removal crews after this particular storm, explained Yves Girard, director of the Cleaning and Maintenance Department at the City of Montreal.

"We can't guarantee the same kind of efficient co-ordination as you would see if there was a storm with less than 30 centimetres [of snow]," he told CBC's French-language service.

The city has many priorities, including hospitals, major roads and secondary streets, where "it can be dangerous for emergency vehicles, such as fire trucks, for example," he said on Wednesday.

The city has removed about a third of the snow that fell during Sunday's winter storm.
