Manitoba's long winter could drive up vehicle insurance rates.

"We know from the fourth quarter results that December, January and February were very difficult for many, many Manitobans,” said Andrew Swan, the minister responsible for Manitoba Public Insurance. 

He said the crown corporation is still crunching the numbers.

“We had some of the worst weather we've ever experienced. It's no surprise that the number of claims for those three months is up, and that puts pressure on MPI," said Swan.

Manitoba's Conservatives said it's time the Public Utilities Board comb through MPI's books to track internal spending.

Tory house leader Kelvin Goertzen said he's been concerned about a potential rate hike for a while. 

"I think the first step with the NDP government is to look at the costs that are happening within Manitoba Public Insurance,” said Goertzen. “We've heard from the Public Utilities Board before that they were concerned about costs increasing within the corporation."

MPI has not released details on if there will be a rate hike in the near future.
