I am moving from California to Vancouver, and planning on driving over the land border. Actually what I realized is the moving company I talked to said I will need to release my belongings at a CBSA office when the driver crosses the border. But since you have to self isolate for 14 days, you basically have to live with whatever you can bring with you for two weeks before you can visit a CBSA office.
And keep in mind new quarantine rules came into effect today . You must show your plan on how you’ll take care of yourself while you’re in quarantine. No concrete plan, your entry could be refused . Or you’ll be put into a government compound for the two week quarantine period
