He didn't say what an essential employee was, I'm a Social Worker, we have letters from our HR department stating "we're allowed on the road, and are considered essential" so I just printed that out in case I was stopped/ asked about it.
That's good they said they would process the COPR....and remember, they told me the same thing that they would process it and we would have to self-isolate. It wasn't until I got to the border that the OFFICER stated I should turn around. We had prepared, packed, and had a place to stay for 14 days, so it was actually their idea....
