I was gifted a Canada property in 2017 from my parents. I was living in the U.S. as a non-resident alien for tax purposes.

In 2021, I became a resident alient for tax purposes in the U.S., so for tax purposes, I was considered a resident in both Canada and the U.S.

The property was sold in 2022. I was living in the U.S. as a resident alien for tax purposes.

Based on the U.S. tax law: www.irs.gov/faqs/capital-gains-losses-and-sale-of-home/property-basis-sale-of-home-etc/property-basis-sale-of-home-etc. The cost basis of a gifted property is the donor's adjusted basis before the donor made the gift.

Based on the Canadian tax law: www.canada.ca/en/revenue-agency/services/tax/individuals/topics/about-your-tax-return/tax-return/completing-a-tax-return/personal-income/line-12700-capital-gains/shares-funds-other-units/identical-properties/property-you-inherit-receive-a-gift.html. The cost basis of a gifted property is the fair market value on the date I received it.

Since I was a non-resident alien in the U.S. in 2017, does that mean the cost basis of my property is the fair market value on the date I received it? The property is considered as my principal residence by Canadian tax law.
