Check out the current regulations regarding USA citizens travelling through Canada to and from Alaska. The border is currently under Covid-19 restrictions, and so normal travel is NOT allowed. Because there have been so many abuses of the exceptions Canada allowed for USA citizens direct travel to/ from Alaska, currently any US citizen traveling through Canada must declare their intention to travel straight through to Alaska, without side trips or sight seeing stops, and the vehicle will be registered in a police database and identified with a special tag system. Time limits are enforced. Abusers have recently been fined and may be jailed. Don't test the patience of the Canadian border police until your COVID 19 cases are under control.
