Dustin Johnson pulled away from the field after a nearly two-hour rain delay to win the RBC Canadian Open for the first time.
Johnson shot a 6-under 66 to finish the only Canadian stop on the PGA tour at 23-under par.
The world No. 1 tied for second in the Canadian Open at Glen Abbey Golf Course in 2013 and 2016.
Golf Canada CEO Laurence Applebaum thought Johnson's victory was an appropriate sendoff for Glen Abbey. The Jack Nicklaus-designed golf course has been slated for redevelopment by ClubLink, the property's owner.
Hamilton Golf and Country Club will host the 2019 Canadian Open. It is also shifting forward in the PGA Tour's schedule, moving to early June in the week before the U.S. Open.
