HSBC’s chief executive Noel Quinn said the decision to sell the business to RBC followed a thorough review on its “strategic fit” within the wider HSBC portfolio. The bank concluded it held a relatively small share of the Canadian market and had greater opportunities for growth in other countries.
“Our group strategy is unchanged, and closing this transaction will free up additional capital to invest in growing our core businesses and to return to shareholders,” Quinn said.
