Ottawa invokes 1977 pipeline treaty in separate Line 5 dispute, this one in Wisconsin
WASHINGTON — For the second time in a year, the federal government is invoking a little-known 1977 energy treaty between Canada and the United States to defend the Line 5 pipeline.
This time, it’s in Wisconsin, where Line 5 skirts the southwestern shores of Lake Superior before crossing into Michigan.
In both states, federal judges are hearing court cases aimed at getting the controversial cross-border pipeline shut down.
An Indigenous band in Wisconsin is arguing that the pipeline’s owner, Calgary-based Enbridge Inc., no longer has the right to operate on its territory.
