I do not know this region, but Google Maps says "Credit Union Central of British Columbia" is at 5506 12 Ave #7, Delta, BC V4M 4C3, Canada. It is three miles away from the Umpqua bank and mostly on the same road.

Living thousands of kilometers away, this bank looks to me to be located in Canada's part of the Point Roberts peninsula. So maybe ChatGPT was not so wrong?
