The National Bank Open’s round of 16 arrives with major stakes in both Montreal and Toronto. By the end of the weekend, the field will be cut to eight men and eight women, and several top names are already under pressure to deliver.

The schedule is spread across Saturday, August 8, and Sunday, August 9, with center-court action set for afternoon and evening sessions in both cities. Montreal has already produced a string of surprises, while Toronto has mostly followed the script so far.

Weekend Schedule and What Is at Stake

The next two days will decide the quarterfinal lineup, and the format leaves little room for error. Each city will host four singles matches per day, with the winners moving on to Monday and Tuesday’s quarterfinals.

• Montreal day sessions begin at 12:30 p.m.
• Montreal night sessions begin at 6 p.m.
• Toronto day sessions begin at 12:30 p.m.
• Toronto night sessions begin at 7 p.m.

The final order of play usually comes out the day before each session, since match length and weather can change the timing.

For players still alive in the draw, the weekend is a test of nerve as much as talent. One bad patch can end a title run immediately.

Montreal Has Turned Into an Open Draw

The men’s event has lost much of its early structure. Alexander Zverev, Daniil Medvedev, Taylor Fritz, and Andrey Rublev were all beaten in their first matches, and Félix Auger-Aliassime withdrew with a back injury.

That left the top half of the bracket far more vulnerable than expected. Six of the top 10 seeds were already out before the second round was complete.

Ben Shelton still looks like the most obvious threat. The defending champion opened with a 6-3, 7-5 win over Jenson Brooksby and arrives with a game built for quick courts.

Casper Ruud also remains in the mix after a sharp 6-1, 6-2 win over Juan Manuel Cerúndolo. Clay has always been his strongest surface, but his hard-court results are strong enough to make him dangerous here.

Players Who Can Use the Chaos

The draw has given several younger names a real chance to move deep into the tournament. Some of them have already taken advantage of the opening.

• João Fonseca stunned Stefanos Tsitsipas in one of the most notable early results.
• Arthur Fils worked through Zachary Svajda in three sets and continues to look comfortable on hard courts.
• Tallon Griekspoor backed up his upset of Zverev by surviving a comeback battle in the second round.

Fonseca stands out because of the pace he can generate from both wings. Fils brings more all-court movement and athleticism. Griekspoor, meanwhile, has already shown that one big win can turn into momentum if he keeps his level steady.

This is exactly the kind of setting where an unexpected semifinalist can emerge. With so many seeds gone, confidence may matter more than ranking.

Canada’s Men Come Up Short

Home interest in Montreal faded quickly. Auger-Aliassime never reached the court, and Gabriel Diallo’s run ended in the next round after he retired against Luciano Darderi while trailing 6-4, 2-3.

Diallo did earn a milestone win by beating Kyrian Jacquet in the opening round, his first main-draw victory in Montreal. Still, there will be no Canadian man in the round of 16.

That leaves local fans to watch the players who have already become central figures in the tournament’s story, especially Shelton, Ruud, Fonseca, Fils, and Griekspoor.

Toronto’s Top Names Are Holding Firm

The women’s draw has been steadier, with the biggest favorites still intact. Aryna Sabalenka, Elena Rybakina, Jessica Pegula, Coco Gauff, and Mirra Andreeva all advanced through their opening matches.

Sabalenka remains the player everyone is chasing. She opened with a 6-3, 6-3 win over Moyuka Uchijima and extended her hard-court winning streak to 13 matches.

Her serve and first-strike power fit Toronto’s pace well, and another deep run would strengthen her grip on the top ranking.

Rybakina needed more work than expected against Daria Kasatkina, but she still won 6-3, 5-7, 6-4 after two hours and 33 minutes. The numbers reflected her style perfectly: 58 winners and 58 unforced errors.

That kind of match can go either way against elite opposition, but it also showed why she remains one of the most dangerous players in the event. If she cleans up the errors, her ceiling is as high as anyone’s.

Gauff, Pegula, Andreeva, and Fernandez

Coco Gauff handled Kayla Day 6-2, 7-5 and did enough in the important moments to stay on track. Her speed and defense continue to be reliable assets when rallies get tense.

Jessica Pegula had the toughest opening match of the group. After dropping the first set against Magdalena Frech, she turned the match around and won 3-6, 6-3, 6-1.

Pegula’s past success in Canada matters here. She has already won the National Bank Open twice, and her comfort level in these conditions is one of the reasons she remains a serious threat.

Mirra Andreeva delivered the cleanest win of the top contenders, defeating Karolina Pliskova 6-0, 6-2 in just 54 minutes. At 19, she is already showing the calm and variety of a much more experienced player.

For Canadian fans, Leylah Fernandez is the last remaining hope in either singles draw. She beat Renata Zarazúa 6-2, 6-2 and now faces Elise Mertens, a skilled opponent who can stretch points and force mistakes.

Fernandez will need to stay aggressive. When she takes the ball early and controls the tempo with her forehand, she can trouble top players on these courts.

The pressure is obvious, though. She entered the event as the only Canadian left in singles, so every match now carries extra weight.

How Fans Can Follow the Action

Sportsnet and TVA Sports are carrying the tournament in Canada, with coverage from both Montreal and Toronto. Their digital platforms are also part of the package for viewers who want to track matches on the move.

Because the timetable can shift, checking the official order of play before each session is the safest way to avoid missing a match.

Saturday and Sunday should bring the clearest picture yet of who can truly contend for the titles. In Montreal, the draw has already broken open. In Toronto, the favorites are still standing, but none of them can afford a lapse now.
