Yep. You have to jump through a few hoops.
1 - Need a negative Covid test no more than 72 hours before entry. Has to be a Rapid test only.
2 - Have to register on the ArriveCAN app. That includes an address where you would be quarantining if needed, although you say you have no where to quarantine. An address is still required. I have used restaurant addresses both times I've entered.
3 - Although you take a picture of your vaccination card, you still need it at the border, because according to some border patrol agents, "cards can be forged". One time the border officer saw the picture and had no issues. The other time the officer wanted to see the actual card. My wife and I presented our Excelsior Pass, and to him that wasn't good enough. Needed the actual card.
4 - Even with all this, you still may be pulled over on a random basis for another Covid test. That hasn't happened to me thus far but the possibility exists.
I wonder what the border officer will say when I go in the next couple of weeks and my destination will be the Duty Free for Alexander Keiths...
