Dustin Johnson posted a final-round 66 at Glen Abbey to claim his third title of the season at the RBC Canadian Open.
Johnson entered the day tied for the lead at 17 under, but after birdies on the opening two holes, he was alone on top and cruised to a 23-under total.
The South Carolina native finished his final day in Canada with seven birdies, one bogey and 10 pars.
The win earned Johnson $1,116,000 and 500 FedExCup points, which strengthens his grip on the top spot on the money list and points standings ahead of Justin Thomas and Justin Rose.
The 34-year old also picked up 46 Official World Golf Rankings points to extend his position as No. 1.
Koreans Byeong Hun An and Whee Kim posted final-round 69s to finish tied for second at 20-under par.
Each took home a check for $545,600, along with 245 FedEx points and 22 OWGR points.
