On Jan. 26 TransCanada Corp . (NYSE: TRP) said it’s working with Manitoba Hydro to restore regular natural gas service to nine communities in the central Canadian province after an explosion on one of its pipelines forced a shutdown on the line.

The ensuing fire, which occurred about 50 kilometers (31 miles) south of Winnipeg early Jan. 25, was put out by around 3 p.m. Eastern time, the Calgary-based pipeline operator said in an emailed statement.

Canada’s National Energy Board is working with TransCanada, police and transportation regulators to determine the cause of the fire.

Trucks with compressed natural gas are making deliveries to hospitals, churches and schools, where those without heat can gather, TransCanada said.

About 4,000 homes in the nine communities don’t have heat, according to the Canadian Broadcasting Corp .
