I am following the Canadian government's travel restrictions closely as I hope to be able to drive to Florida at some point this winter.
However, I am a little unclear about the U.S. Border Closure and the government Travel Advisory. Are they the same thing or are they unrelated?
The Canada/U.S.Land Border Closure, which prohibits "non-essential" travel by land between Canada and the U.S. and the Government of Canada Level 3 Travel Advisory, which advises Canadians against all non-essential travel to virtually ALL countries in the world (as of October 1st, 2020) are NOT tied together.
For example, the land border restrictions could be lifted or modified while the Level 3 travel advisory remains in place. Conversely, the travel advisory could be modified or reduced to Level 2 while the land border could remain closed.
Normally, travel advisories are country or even region specific. This one is unique in that it applies to virtually everywhere. Eventually, the travel advisories will likely be modified to warn of the specific level of risk in a country or region.
