Our trip is fast approaching and I'm left wondering what we should use as our proof of vaccination. We're in BC and have our proof of vaccination QR codes and inoculation appointment cards, but no official international paperwork.
Our outbound trip is Vancouver > Dallas > Austin > San Juan > Beef Island
Return is Beef Island > Saint John's > Toronto > Vancouver
We will be passing through the airports of four countries. As this will be our first time is there anything we must be aware of that we might not be?
