(Reuters) - National Bank of Canada (>> National Bank of Canada) reported a better-than-expected quarterly profit on Wednesday, largely boosted by its wealth management and personal and commercial businesses.

Canada's sixth-largest bank said net income in its personal banking and commercial business rose 18.3 percent to C$213 million ($159.91 million), helped by higher personal mortgage lending.

Net income in its wealth management business rose to C$101 million in the first quarter ended Jan. 31 from C$77 million.

The bank said its core tier 1 capital ratio, a key measure of its financial strength, increased to 10.6 percent, from 10.1 percent a year earlier.

Excluding certain items, the bank earned C$1.35 per share, handily beating the average analysts' estimate of C$1.26, according to Thomson Reuters I/B/E/S.

National Bank of Canada is the latest Canadian lender to report a better-than-expected quarterly profit.

Bank of Montreal (>> Bank of Montreal) and Laurentian Bank of Canada (>> Laurentian Bank of Canada) also beat on profit estimates, while Bank of Nova Scotia's (>> Bank of Nova Scotia) earnings were broadly in line.
