Dwolla with Canadian bank

Hi,
I’m wondering if Dwolla support the client can link their Canadian bank account with US based business?
Since I always get ITEM_NOT_SUPPORTED error code in the sandbox environment. (Plaid + Dwolla)
Appreciate for any supportive response.

Unfortunately we only support US bank or credit union accounts at this time. The API performs validation based on an ABA routing transit number (ABA RTN).
