Why is Justin Trudeau pressuring Michigan to allow a dangerous oil pipeline? | Lana Pollack

If an ageing pipeline under the Great Lakes spills, it would be devastating. But Canada is trying to block Michigan from shutting it down

Canada would be apoplectic if the US government marched into a Canadian court and argued that the province of Ontario has zero authority over an American company operating an aging, corroded pipeline under Canada's pristine Georgian Bay. Yet this is the exact approach Canada is taking in US courts by arguing that the state of Michigan has zero authority to order the shutdown of an aging and dangerous pipeline operated by a Canadian company under the Straits of Mackinac - where any spill would have catastrophic ramifications for the Great Lakes.

Canada's strained position is premised on ignoring the plain text of the 1977 US Canada Pipeline Treaty: Pipeline[s] shall be subject to regulations by the appropriate governmental authorities ... with respect to such matters as the following: (a) pipeline safety ... ; (b) environmental protection."
