COQUITLAM, B.C. - Lydia Ko won the CN Canadian Women's Open to become the youngest golfer ever to win an LPGA event.

The 15-year-old from New Zealand shot a 5-under-par 67 today at the Vancouver Golf Club, finishing with a 13-under 275 total to beat Inbee Park of South Korea by three strokes.

Ko is also the first amateur to win the Canadian Women's Open and does not receive the winner's cheque. She's the fifth amateur to win an LPGA tournament and first since JoAnne Carner of the U.S. back in 1969.

Ko surpassed American Lexi Thompson as the youngest LPGA Tour event winner. Thompson won the Navistar LPGA Classic last September at age 16.

Ko is not the youngest golfer to win a professional event, though. That honour now belongs to 14-year-old Brooke Henderson of Smiths Falls, Ont., after she won a Canadian Women's Tour event in Quebec in June.

Jessica Shepley of Oakville, Ont., the lone Canadian to qualify for the weekend, posted a 1-over 73 and finished with a 2-over 290 total.
