Too bad that the Federal and Ontario governments are no longer significant shareholders of GM. The equity stake, purchased at the time of the 2008 crash, and sold off (cheap) a few years later, might have provided the Canadian government a little leverage in Trump's 'Buy America' sweepstakes. 

Oh well, as an alternative, maybe the current governments can buy those soon-to-be vacant GM factories back from (for a healthy, taxpayer-funded premium) to crank out electric cars so that Canadians can meet their emissions targets. 

Potential spin-off benefit: new demand for Ontario's premium-priced 'green' electricity, once cars built in the US by newly re-domesticated 'Big Three' are legislated out of existence in the coming trade war, to be supplanted by eco-chic cars built by our free-trading European and Asian partners.
