“This is just the latest development in long-standing efforts by Michigan’s executive branch against a vital energy corridor for the state.  

“Like so many regulatory matters concerning pipelines, it is expected that the latest move announced today will be headed to a long, protracted process in the American court system. 

“Line 5 has provided Michigan with 65 per cent of the propane that heats homes in the Upper Peninsula while also providing neighbouring states, Ontario and Quebec with reliable safe energy. The project is a critical piece of infrastructure that is being made even safer through the Great Lakes Tunnel Project and can provide the energy still required for the coming decades.”
