Amending GTF list

Hi everyone! I completed my soft landing in 2018 at the Toronto airport on way to India. I had submitted a goods to follow list at that point, but had not added my car in that list. I was only in Canada for the sake of the soft landing (2 days) at that time.

I will be moving permanently to Canada this February. But now, I have changed my mind and I want to take my car (which I will be driving). As this is the definition of a settler according to IRCC website, would I be allowed to amend my list of GTF, or bring the car duty free?

Thanks in advance for any help and suggestions!
