I remember from other posts that they didn't allow some people even for a shorter stay. I personally talked to a CBSA officer on phone last month and he said clearly that I would not be allowed if I want to enter Canada in a personal car that has a lien. So I would recommend you to reach to the CBSA and confirm before your travel.I am in a similar situation as i was planning on living in windsor for a little while (till family is ready to move) with my american vehicle that has a lien on it but i guess with the borders closed i wont be able to drive back unless i am deemed an essential worker, which i am not. any thoughts?
