Here's a nightmare scenario to consider. In two weeks Trump expects life to be normalized for the Easter weekend. By then he will have marginalized and discredited all his senior health advisers and trotted out his own "experts" to bolster his assertion that the US is recovering. For us, that that American normalization may come with pressure on Canada to normalize international trade and travel.
Consider, now, a whole fleet of truck drivers from the US who have been exposed trough normalization heading towards Canada with essential goods.
Add to that a host of Americans heading here to open their cottages and enjoy long weekends away from the stress of pandemic stricken big city (e.g. New York) life and expecting to not be turned back at the border because America has resumed "business as usual" according to the Oval Office.
What then?
