We just trialled the border process required to return from the USA. We chose the Aldergrove crossing as it is the closest to our home. The system requires some pre-planning (a Covid test that is only good for 2 days and an online ArriveCAN system to fill out before returning). Overall not too onerous. The tests did cost $60.00 per person and you get your results in 30 minutes. The border wait was non-existent (We were the only vehicle there as we drove up)
On our way back we stopped at the Coast Artillery Museum in Fort Worden. Definitely a spot to put on a future itinerary! Maybe we could offer volunteer time for accommodation?
