Non US Citizen Business Owner

We have a non US citizen that is a business owner living in Toronto CA. On the Signature card the business address is located in Mississauga ON. The EIN application states that the business is located in Albany NY, ??

My question is:
1) Does a non US citizen that owns a business and had an EIN number registered within the US - do they also need to have a ITIN for the owner of the business?
2) Our Personal Banker that opened the account only obtained the application of the EIN or the official letter should we request the official letter from the IRS?

I am not aware of any requirement that an owner of a US business that is not a US person being required to have a ITIN?

OK thanks!
