Johanna Konta missed out on a spot in the quarter-finals of the Rogers Cup after losing 6-3 6-4 to defending champion Elina Svitolina.
The British No 1 had completed a rain-interrupted second-round clash with Victoria Azarenka earlier in the day, but could not continue her momentum in the third round.
Konta, who was leading former world No 1 Azarenka 6-3 3-0 on Wednesday before rain forced an overnight delay, returned to wrap up the match in comprehensive fashion 6-3 6-1.
But Svitolina took just 85 minutes on court to dismiss Konta in straight sets and move through.
US Open champion Sloane Stephens beat Spain’s Carla Suarez Navarro 6-2 7-5 to book her spot in the quarter-finals, where she will face Latvia’s Anastasija Sevastova, a 6-3 7-6 (7-2) winner over German 10th seed Julia Goerges.
Australian 15th seed Ashleigh Barty also made the quarter-finals by seeing off Alize Cornet of France 7-6 (7-3) 6-4.
