He should also put export tariffs on electricity to lower demand/price of PQ electricity (or subsidize their electricity from tariff proceeds) that is main cost of aluminum production. Buying a strategic reserve of Aluminum will keep factories open, and allow better deals/pricing for “allies” or new friends, or later dumping on US when they end the trade war.
Better to not coordinate. Trump comes up with new problems for Canada on a regular basis, only fair we do the same to him.
I feel like co-ordinating on these things would be better. BC, ON and QC all have steel and aluminium industries to defend, and all three provinces export a decent chunk of electricity to nearby US states.
A co-ordinated surcharge on electricity would be a powerful response to the inpatient at the white house.
