Generally, the USMCA itself would not be impacted by anything in this tax treaty. Generally speaking, the USMCA provides that, to the extent that there's a tax treaty in place, the tax treaty should apply, as opposed to the USMCA.
The fact that the United States is not going to sign this convention should not have any significant impact. That is because the U.S. already has in its bilateral tax treaties with all of its partners the main provisions contained in this multilateral convention. For example, on the treaty anti-abuse rule, the United States for some time has had a policy of including a treaty anti-abuse rule in its tax treaties, which is generally referred to as a limitation on benefit test. That test is included in the Canada-U.S. tax treaty. It is also included in the U.S.-Mexico treaty. My understanding is that it is in all of the U.S. treaties with the exception of two, and I think it has already renegotiated those treaties, although they have not yet been ratified, and in one case, one may not be signed.
We don't think there will be significant impact, because they already incorporate many of these anti-abuse rules in their treaties.
