People in Regina and Saskatoon are going to find out what it feels like to get left out in the cold tonight.

As much of eastern Saskatchewan experiences cold weather warnings from Environment Canada, the two largest urban centres in the province are joining cities across the country in hosting a Coldest Night of the Year fundraiser.

The Coldest Night of the Year fundraiser is happening this weekend in 91 locations across Canada from Victoria, B.C. to St. John's, N.L.

The event usually features two-, five- and 10-kilometre walks, all in the name of raising awareness and money in the fight against homelessness and poverty.

However, the Coldest Night of the Year website states that due to cold-weather conditions in Saskatoon, only the five-kilometre walks will take place. The situation was being closely monitored on Saturday morning in Regina, where Environment Canada had issued an extreme cold weather warning.

Registration opens at 4 p.m. CST at the Lighthouse in Saskatoon and at 4 p.m. at 1475 Athol Street in Regina.

Event benefits local charities

In Saskatoon, proceeds will go to The Lighthouse Supported Living emergency shelter and affordable housing service as well as the Bridge Fellowship Centre.

Sarah Enns, a representative of the Bridge, explained to CBC's Dani Mario that the ministry will use the money to fund operational expenses.

"We run a transition home for men, and our day-to-day expenses as we're expanding are also growing, and so that's what we're going to be using it for," Enns said.

DeeAnn Mercier with the Lighthouse added that her organization relies on these funds to operate a mobile outreach vehicle.

"That vehicle needs gas and repairs and all that sort of stuff," Mercier said.

Regina's Coldest Night of the Year will benefit the Soul's Harbour Rescue Mission.
