Dec 1 (Reuters) - Canadian Imperial Bank of Commerce (CIBC) CM.TO, Toronto-Dominion Bank TD.TO and Bank of Montreal BMO.TO on Thursday joined their bigger peers in setting aside more money to cover potential loan defaults by inflation-hit customers. TD Bank's bigger U.S. presence boosted its loan growth and helped offset the hit from higher provisions for credit losses (PCLs). With more than half of its total loans being in residential mortgages, CIBC set aside C$436 million in PCLs, up more than fivefold from last year.
