IF the Feds truly try and throttle back on Canadian energy exports to the states, Its quite possible that the Enbridge Line 5 permits and regulatory approvals will come back into play. Lets not forget that this line supplies a large amount of the crude feed for the Eastern Canadian Refineries. Michigan would dearly love to be able to close in that pipeline but were beat back from the valve due to the Canadian federal govt intervention, citing a treaty drafted in 1977 about free flow of energy across the border. I highly doubt Canada wants to wade into this mess again
'In August 2022, the Canadian government again invoked a 1977 treaty with the United States in order to prevent the shutdown of the pipeline in Wisconsin, citing concerns about jobs, energy security, and the economy. Canada, which backs Enbridge, invoked the treaty for the first time in 2021 when the state of Michigan attempted to shut down Line 5 under the Straits of Mackinac due to environmental concerns.[37][22]'
