EFT different bank country/region

Here the situation: In a functional US company, we have a US checkbook account in the Country/Region "Canada" and we want to pay a USA bank for a US vendor (Bank Country/Region "United States"), but when trying to do so, we get the message that the Bank Country/region assigned to the checkbook is different then from the Bank Country/region assigned to the Vendor remit to adress...  Is it possible in EFT, to pay a US vendor in a USA bank from a US Canadian bank account?  What setup needs to be done?

Thanks!
