Receiving a published "thank you ABC Bank for your support" does not disqualify a donation. Rather, look at what the donation is doing. If it is directly benefitting the qualified group's programs and services, you should get CRA credit for it. In contrast, event sponsorships (like dinners and galas) are problematic. Examiners often reject those donation dollars because they are spent on catering, venues, table rentals, etc.
Confirm that the bank's donated funds are directly going in support of the group's program / services: either by obtaining a letter from them; or by you sending them a letter stating that funds are to be used directly for programs and services only.
