A prolonged cold snap has led to concerns about the welfare of vulnerable people in Saskatoon. The social agency, The Lighthouse, has been driving around the city providing blankets and handwarmers and transporting people to the shelter as part of its mobile outreach program.

The Lighthouse's van has been out on patrol for more than a week now and staff say it will continue to run seven days a week. It's also looking for help from others in the community.

"We've made contact with a lot of businesses in the core neighbourhoods. And also just some of the places where people are sleeping in, in different stairwells. There was a heated stairwell downtown that we keep frequenting to go see if this guy is camping out there," said Tommy Laplante, an outreach worker with the organization.

Laplante said Wednesday the mobile outreach crew have water on hand, along with blankets, jackets, mitts and handwarmers to hand out to those in need.

So far the crew has helped close to two dozen people.
