Enbridge: Line 5, Michigan-to-Canada, back in the news. Link here.

Line 5 begins at Superior, Wisconsin, where Canadian crude and NGLs flow off Enbridge’s Mainline system. From there, the line cuts across Michigan, supplying propane to the Upper Peninsula and feedstock to refineries in Detroit and Toledo, before ending in Sarnia, Ontario. That makes Michigan both a customer and a corridor, while Canada has a double stake—as both a producer shipping oil east and a consumer depending on Sarnia’s refineries.
