Lydia Ko's got a fair bit of ground to make up after a steady opening round in the LPGA event in Ontario.

The Kiwi teenager has carded two birdies and two bogeys in an even par round of 71.

Ko is in a tie for 54th, six shots off the pace.

American Michelle Wie and and Korea's Hee Young Park have a one shot lead at six-under par.
