It won't be easy for Canada's Milos Raonic if he makes it through the first few rounds of the French Open.
The fifth seed from Thornhill, Ont., could potentially meet Grigor Dimitrov in the round of 16 and may face Rafael Nadal in the quarter-finals. Raonic, who's in the bottom of the draw in the same half as defending champion Novak Djokovic, will open against world No. 38 Steve Darcis of Belgium.
Raonic reached the fourth round at Roland Garros last year before falling to Spain's Albert Ramos-Vinolas.
There are two Canadians entered in women's singles play. Eugenie Bouchard of Westmount, Que., is set to open against No. 72 Risa Ozaki of Japan while Montreal's Françoise Abanda qualified for the main draw Friday with a 6-3, 6-2 victory over Su Jeong Jang of South Korea.
It's unclear if the 56th-ranked Bouchard will be able to play as she suffered an ankle injury at this week's Nuremberg Cup. Abanda, the world No. 191, will open against No. 264 Tessah Andrianjafitrimo of France.
Nadal, meanwhile, is back in top form as he starts his quest for a 10th French Open title.
The 14-time Grand Slam champion – who is seeded fourth this year – will need to deal with the talented and unpredictable Benoît Paire in the first round.
"I know I need to be ready since the beginning, because I have a tough opponent in the first round," Nadal said. "So I am focused on trying to work the right way."
The 30-year-old Nadal, who retired last year before his third-round match with a wrist injury, has a 72-2 record at the clay-court major and is the only player with nine trophies from one Grand Slam tournament.
This season, he has been the dominant player on clay, winning 17 straight matches on his favourite surface and three consecutive titles before Austrian Dominic Thiem halted his run in Rome last week. In Paris, he could face Djokovic or Thiem in the semi-finals.
"I had a lot of success on clay, winning three events out of four I played," Nadal said when asked about his fitness. "That's great for me, no? It makes me happy to feel myself competitive and play well in every event that I played. I am very happy the way that I arrived here. Now I have to play well here. That's all."
Djokovic can't boast the same confidence as his Spanish rival after struggling with form and confidence recently.
"Rafa, next to Roger [Federer], has been the best player this year in terms of results," Djokovic said. "Their level of tennis is quite fantastic. Rafa is playing on his favourite surface and playing with confidence, much better than last year. I definitely see him as probably the No. 1 favourite for this title."
Federer, who won the Australian Open in January, is skipping Roland Garros, focusing instead on his preparations for the grass and hard court events.
So much has changed for Djokovic since he completed a career Grand Slam at the French Open last year by beating Andy Murray in the final.
The Serb's form nosedived after his triumph on the Parisian red clay as he lost in the third round at Wimbledon for his earliest defeat in a Grand Slam in seven years. He was then beaten in the first round at the Rio de Janeiro Olympics, reached the final of the U.S. Open, and lost early again at the Australian Open.
Djokovic, who lost his No. 1 ranking to Murray last year, has won only one of his past 11 tournaments.
"It's an amazing feeling to be back and to look at this trophy. It brings back memories from last year," Djokovic said at the draw ceremony. "Winning here was one of the most special feelings on the court, one of the highlights of my career."
Djokovic, who hopes new coach Andre Agassi will help him turn his luck around over the next fortnight, will start the defence of his title against 76th-ranked Marcel Granollers.
The top-ranked Murray, who will open against Andrey Kuznetsov, was drawn in the same half as third-seeded and 2015 champion Stan Wawrinka, who he could meet in the semi-finals. Before that, he faces a potential difficult match-up against Juan Martin del Potro in the third round if the Argentine player recovers in time from shoulder and back problems.
In the absence of Serena Williams and Maria Sharapova, the women's draw is looking wide open this year. An intriguing first round match-up will put defending champion Garbine Muguruza against 2010 champion Francesca Schiavone, while top-ranked Angelique Kerber will take on 40th-ranked Ekaterina Makarova.
Among the other favourites, third-seeded Simona Halep will be up against Jana Cepelova in the first round if her right ankle injury does not prevent her from playing.
The tournament will also see two-time Wimbledon champion Petra Kvitova making her comeback less than six months after she was stabbed during an attack at home in the Czech Republic.
"Not many people believe that I can play tennis again. So I'm happy that I can play. I actually already won my biggest fight," Kvitova said. "I'm happy that I like challenges. That was one of the biggest, of course. So I stayed in life and I have all my fingers, I can play tennis and I can be here and be in the draw."
Williams is not playing because she is pregnant, while Sharapova's ranking wasn't high enough to gain direct entry into the tournament after a 15-month doping suspension. Tournament organizers did not grant her a wild card.
Play begins on Sunday.
