Canada needs to create an "Economic Reparations Fund" to help those workers and companies harmed by trump's tariffs. Its initial funding should come from selling $10B of US bonds (Canada is ~5th largest holder) and a 5% surcharge on oil exported to the US. US already extracts a 12-22% discount off world oil prices from Canada (who's taking advantage of who?) so 5% shouldn't be an issue. As needed to cover damages, more bonds could be sold and the oil surcharge could be raised.
