OTTAWA -- The mayor of Sarnia, Ont. warned that the Enbridge Line 5 dispute could foreshadow challenging times ahead for the Canada-U.S. relationship.

鈥淎fter four years of what we went through with Trump, we thought we were in a better place, a better day,鈥 Mayor Michael Bradley told 麻豆影视 Channel鈥檚 Power Play on Wednesday. 鈥淚t appears we鈥檙e not,鈥 he said.

Michigan Gov. Gretchen Whitmer ordered Enbridge's Line 5 pipeline to close on Wednesday but with Enbridge and Michigan awaiting meditation it remains unclear if, or when, that will actually happen.

The Biden administration halted the Keystone XL pipeline in a string of executive orders during the president鈥檚 first day in office, despite unheeded pleas from Canada's federal government.

The Canadian government filed a legal brief Tuesday in U.S. District Court for the Western District of Michigan to support Line 5.
