Day four report
World number one Dustin Johnson has claimed his third PGA Tour title of the season and 19th of his career as he eased away to a three-shot victory at the Canadian Open.
Johnson is now the 10/1 outright favourite to win the US PGA Championship, the final major of the year, which is being staged at Bellerive Country Club on August 9.
Johnson shot 66 to finish on 23-under for the tournament at Glen Abbey Golf Club in Oakville to break away from a four-way tie for the lead he was involved in overnight.
In bouncing back from missing the cut at the Open, Johnson shared the lead overnight with Kim Meen-whee, An Byeong-hun and Kevin Tway, but dropped just one shot in the final round.
Kim and An finished on 20 under, both mixing five birdies and two bogeys for a final round of 69.
American Tway, whose father Bob won the same tournament at Hamilton Golf and Country Club in 2003, endured a disappointing afternoon, hitting five bogeys and just one birdie to finish tied for 17th.
Keegan Bradley recovered from a third-round 73 to fire a blemish-free eight-under 64 and finish a shot behind Kim and An.
Tommy Fleetwood was the best-place Briton, tied in sixth on 16 under after sinking an eagle on the par-five 13th hole. Ian Poulter ended in joint 12th on 14 under.
Day three report
World number one Dustin Johnson moved into a four-way share of the lead through three rounds of the RBC Canadian Open.
Johnson started the day three adrift of Kevin Tway, but birdies at five of his first six holes saw him storm to the top of the leaderboard.
Bogeys at the 10th and 13th holes threatened to derail his challenge, but Johnson birdied the 14th despite having found a fairway bunker from the tee, added another at the par-three 15th and then blasted his way to an eagle at the par-five 16th following a 374-yard drive.
Although frustrated not to add another birdie having missed chances at each of the closing two holes, Johnson will play in the final group on Sunday.
Alongside him will be Byeong Hun An, who produced by far his best putting display of the week in a round of 66 which ended with a 33-foot birdie at the 18th.
Tway also birdied the last to reach 17-under and will again tee off with Whee Kim on Sunday, the Korean having made a mistake at the 17th which cost him sole possession of the lead.
Kim had leapfrogged Johnson with a curling eagle putt at the 16th hole, but a wayward drive at the next proved costly as a five-five finish made it a four-way tie at the top.
The quartet have a four-shot cushion over the chasing pack, headed by Hudson Swafford and Rory Sabbatini.
Day two report
Kevin Tway will be hoping to follow in his father's footsteps as he takes a one-shot lead into day three of the RBC Canadian Open.
The American, whose father Bob won the same tournament at Hamilton Golf and Country Club in 2003, recovered from a bogey on the 17th to finish with a birdie on the final hole and get to 13 under in Oakville, Ontario.
South Korean Whee Kim matched Tway's second-round 65 to finish on 12 under overall and was joined in second place by American Keegan Bradley.
Bradley, a 66/1 tip by Sporting Life's golf expert Ben Coley pre-tournament, eagled the par-five second hole and closed on nine-under 63 following an impressive birdie-eagle-birdie-eagle finish through holes 15 to 18.
England's Tommy Fleetwood had a disappointing day, mixing six birdies with five bogeys for a round of 71 and dropping 19 places into joint 23rd.
Day one leader Robert Garrigus moved into joint 10th on nine under following a round of 72 which included four bogeys and birdies apiece.
Day one report
Robert Garrigus had a one-shot lead in the opening round of the RBC Canadian Open before play was suspended for the day due to dangerous weather.
The American, who had completed his round before thunderstorms interrupted play, carded a blemish-free nine-under 63 - including five straight birdies in his first six holes.
He added four more on the back nine, helped by a stroke of luck on the 13th when his ball hit a rock to save it from the water.
Closest rival Adam Schenk shot 10 birdies and two bogeys to finish on 62, while compatriot Chris Stroud was third with 65.
Ian Poulter, Hudson Swafford and Byeong Hun An all finished a shot further back, while Kevin Tway was also sitting on six under with three holes left to play.
Two-time defending champion Jhonattan Vegas was two under through 16 holes.
Play was suspended due to the weather at 4.30pm ET (9.30pm BST) and resumed just over two hours later. It was stopped again for the day at just after 8pm ET (1am BST).
Following the first break, Tommy Fleetwood shot up the leaderboard after hitting two eagles and two birdies in four holes. He finished the day on five under with two holes still to play.
The round is due to resume at 7am ET (12pm BST) on Friday, with round two scheduled to get under way half an hour later.
