So how do you justify the movement of goods between the two countries at the land borders? I'm not being argumentative, I'm truly trying to understand how Canadians do not view that as non-essential? As an industrialized nation, what is Canada not able to generate (save for perhaps tropical fruits) that needs to be sourced from the USA right now (and vice versa)? And for a virus this deadly, can a country not live without those few items for the short term? (eat an apple instead, they really are good for you) Surely you can see that a truck driver, who would be frequenting rest stops and fast food outlets all along his route, would be statistically putting himself in many more Covid-catching situations than many average citizens, a good deal of whom have been working from the safety of their home during the pandemic?
To say it's black and white is nonsensical. The world is connected in more ways than any of us can understand. I hope you are also advocating for every Canadian who lives in a border city (nurses and medical staff included) to cease their employment until this virus is under control, because by your logic we don't want the Canadians from Windsor bringing Covid into Michigan hospitals (the super-strain was identified in Canada before it was identified here.....and health care workers are at a far greater risk of exposure than us "regular" folks).
Not everyone who is traveling from one country to another is doing so for a "vacation". I personally know a few people who have had to travel home to prepare final arrangements for loved ones who have passed away (and none of those people died from covid, for the record). Others need to care for relatives with cancer, or who have been gravely injured in an auto accident (with young children who need care). Please try and open your mind to realize that not everyone wants to jaunt across the border to go to Disney World or host a house party with 30 friends. For someone who has lived their whole life in one country and doesn't have connections outside of those borders, its easy to wear your blinders and pretend life is that small. Let me assure you it isn't.
