They’ve pulled off the temporary signs, and traded in all those logos: today the former M&I bank officially becomes BMO-Harris Bank, after the Chicago holding company bought M&I last July.

BMO-Harris is a subsidiary of the Bank of Montreal. The transition has been going on over the last 15 months.

Sometime on Tuesday, the M&I bank web site was expected to be deactivated. Customers should now use the BMO-Harris Web site at www.harrisbank.com.
