The Canada Energy Regulator (CER) said work was stopped at the TC Energy’s NGTL Edson Mainline work site near Caroline, Alberta, after it was notified of a serious, non-fatal injury on Thursday.
The NGTL System transports natural gas from Alberta and northeastern British Columbia and connects with TC Energy’s Canadian Mainline, Foothills System, and other third-party pipelines.
The system supplies natural gas produced in the Western Canadian Sedimentary Basin to markets in Canada and the United States.
The company was not immediately available for a comment.
