Had a call today from someone wishing to transit Canada from the Lower 48 to Alaska, and from folks looking at Alaska-Canada Travel..
We posted previously about this (https://www.transcanadahighway.com/new-conditions-for-us-travellers-transiting-to-alaska/), but checked to see if there were any changes:
1) Only necessary travel, and only ONE WAY, not vacation travel (only northbound, if you have Alaska plates and drivers licence; and southbound only with Lower 48 plates)
2) When entering Canada at a land border crossing, you will be provided with two COVID-19 Specimen Collection Kits: one to use on the day you arrive in Canada and another to use on day 8 of your 14-day quarantine.
Still the same: need the car hang-tag, no sightseeing detours (visitors to Banff or Whistler have been heavily fined and summarily tossed out), must self isolate the whole way, and no dilly-dallying. See the full rules
