Reigning US Open champion Dustin Johnson fired a six-under par 66 to seize a share of the lead at the PGA Tour's Canadian Open at Glen Abbey Golf Club. The 11-time PGA winner made seven birdies, an eagle, a bogey and a double bogey to move into a tie atop the leaderboard with Luke List at the Toronto-area course. Johnson, who won the US Open last month at Oakmont, is making his fourth start in the Canadian Open.
