Merger of Imperial and Commerce The origins of the Imperial–Commerce merger lay in the actions of
Barclays Bank. Barclays began operating in Canada in 1929, but in 1956 sold its Canadian operations to the Imperial Bank. Barclays took payment partly in the form of Imperial stock. In 1960, without informing Imperial's board, Barclays began buying additional Imperial stock on the open market.
L. Stuart Mackersy, chairman of Imperial, believed Barclays was making a play to take over Imperial. Mackersy thought that a takeover of a small bank such as Imperial was inevitable, but preferred to work with domestic rather than British concerns. In October 1960, Mackersy approached
Neil J. McKinnon, the president and chairman of the Commerce, with a proposal to merge the two banks. Their first meeting took place secretively at McKinnon's house at 116 Dunvegan Road in
Forest Hill, making the house the birthplace of the CIBC. According to Mackersy, within ten minutes he and McKinnon reached an agreement to merge their banks.
Operations of CIBC On 1 June 1961, the Canadian Bank of Commerce and the Imperial Bank of Canada merged to form the Canadian Imperial Bank of Commerce with over 1,200 branches across Canada. The new bank possessed the greatest resources and the most branches of any bank in the country. In 1964, the bank operated a floating branch using the passenger vessel MV
Jean Brilliant along the north shore of the
St. Lawrence River in
Quebec, billed as the only floating branch in Canada for 5000 customers. In 1967, both Canada and CIBC celebrated their centenaries and CIBC was the only chartered bank to have a branch on-site at
Expo 67. Also at this time computerization began to change banking services and the Yonge and Bloor branch in Toronto was the first Canadian bank branch to update customer bank books via computer. This also marked the introduction of inter-branch banking. Before the decade was out, CIBC had introduced the first 24-hour cash dispenser, which would eventually become the ATM. Following the merger, the new bank commissioned a new head office. While planning to retain Commerce Court North, the bank hired architect
I. M. Pei to design a three-building complex. The result was Commerce Court consisting of a landscaped courtyard complementing the existing building and included the newly built Commerce Court West. When completed in 1973, the 57-storey building was the tallest in Canada, and the largest stainless-steel-clad building in the world. and
Bay Street. The building was used as CIBC's head office from 1973 to 2021. Changes to federal and provincial regulations ending the separation of banks, investment dealers, trust companies and insurance companies came in 1987. CIBC quickly took advantage of this and became the first Canadian bank to operate an investment dealer, CIBC Securities, offering services to the public. In 1988, CIBC acquired a majority interest in
Wood Gundy which brought a well-respected name and reputation in underwriting. Shortly thereafter, the corporation merged Wood Gundy and CIBC Securities under the name
CIBC Wood Gundy which became CIBC Oppenheimer in 1997 and later,
CIBC World Markets. In 1992, CIBC introduced automated telephone banking; in 1995 the bank launched its website, and shortly thereafter began offering banking services online. In 1996, CIBC formed HP Intria Items, alongside
Hewlett-Packard and Fiserv Canada. In 2005, CIBC acquired the shares of the company from Fiserv Canada, resulting in Intria Items becoming a unit of CIBC. In 1998, CIBC joined with
Loblaws to create
President's Choice Financial which it launched in 28 Ottawa area stores. CIBC agreed to merge with the
Toronto-Dominion Bank in 1998. However the
Government of Canada, at the recommendation of the
minister of finance,
Paul Martin, blocked the merger – as well as another proposed by the
Bank of Montreal with the
Royal Bank of Canada – as not in the best interest of Canadians.
21st century In 2000, CIBC signed an agreement with the New York-based Aplettix Inc., a firm specializing in secure transaction systems in the banking sector; although the partnership was later abandoned for alternatives such as VeriSign.

Barclays Bank. Juniper Financial was previously acquired by CIBC in 2001. The bank sold EDULINX Canada Corporation to Nelnet Canada Inc., the Canadian unit of
Nelnet, Inc., in late 2004.
Li Ka Shing was the largest foreign shareholder in the bank for over two decades, but in early 2005 he sold his portion (est. CA$1.2 billion) to establish a Canadian charity, the Li Ka Shing Foundation. CIBC was Li's choice for financing many of his Canadian ventures, like
Husky Energy. Li had reportedly backed personal and commercial banking head
Holger Kluge to succeed Al Flood as CEO of CIBC in 1999. CIBC sold its corporate and purchasing credit card business to
U.S. Bank Canada in October 2006 which joined it with business charge cards it previously acquired from
Royal Bank of Canada. In the same year, CIBC's stock ticker symbol on the

CIBC FirstCaribbean International Bank in 2011. On February 12, 2009, the
