TORONTO, June 1 (Reuters) - Bank of Nova Scotia beat analysts’ estimates for quarterly profit on Tuesday, driven by strength in its Latin America-focused international unit and a sharp drop in provisions to cover loan losses. Net income excluding one-off items rose to C$2.48 billion ($2.06 billion), or C$1.9 a share, in the three months ended April 30, compared with C$1.37 billion, or C$1.04, a year earlier. Analysts had expected C$1.76 a share, according to IBES data from Refinitiv. Canada’s No. 3 lender reported overall net profit of C$2.46 billion, or C$1.88 a share, up from C$1.32 billion, or C$1 a share, a year ago.
