"Variation Between Customs/Immigration Legislation
9. A person's status for customs purposes is not always the same as their status for immigration purposes.
10. As an example, a person can become a permanent resident without the intention of residing immediately in Canada. However, this person is not determined to be a settler as defined in the customs legislation, and be eligible for the provisions of tariff item No. 9807.00.00. In this case, since the person does not have any intention of remaining in Canada at that time, and will live outside Canada for an undetermined period of time, that person is considered a non-resident of Canada and not a settler, for the purpose of the Customs Tariff, and is eligible to temporarily import goods under tariff item No. 9803.00.00."
When you Soft landed earlier you became a Canadian Resident from immigration perspective but were just a visitor from Customs perspective. In fact, you were not even required to submit GTA/GTF during soft landing. For Customs, you will become resident once you move to Canada and establish residency ( means actually start living in Canada).
When you call CBSA do mention that you have no residential ties to Canada at this moment. A friend's/releative's address where you sent your PR card does not count
