Canadians Frank Dancevic, Peter Polansky and Milos Raonic are all pitted against tough first round opponents at the Rogers Cup, the result of the draw held on Friday.

Dancevic, of Niagara Falls, Ont., is scheduled to face Stanislaw Wawrinka of Switzerland at the tournament that begins in earnest Monday at the Rexall Centre at York University.

Should he knock off the No. 23 player, Dancevic could have to face the top player in the world, Rafael Nadal of Spain.

Dancevic gave Nadal a spirited run at the tournament in 2007, winning the first set before bowing to the Spaniard in three sets.

All four Canadian players in the tournament are wild card entries.

Polansky, of Thornhill, Ont., faces Jurgen Melzer of Austria. Melzer is ranked a career-high 15th after a strong start to the summer, with a semifinal appearance at the French Open and a fourth-round exit at Wimbledon.

With injuries riddling Dancevic in recent months, Polansky has taken over as the highest ranked Canadian, at No. 200 in the rankings.

Raonic, also from Thornhill, takes on Romanian veteran Victor Hanescu.

Pierre Ludovic-Duclos of Sainte Foy, Que., will take on a qualifier to be determined this weekend.

The tournament is expected to feature its five most recent champions, all of whom are currently ranked among the top 10 in the world: Andy Murray, Nadal, Roger Federer, Novak Djokovic and Andy Roddick.

Nadal and Federer, with 24 Grand Slam singles titles between them, could meet in the final in Toronto as they were slotted into opposite sides of the draw.

Nadal is the top seed, with Federer third behind Djokovic. Nadal and Federer have met just once in 2010, a clay court victory in Madrid for Nadal

The top half of the draw features Nadal, Roddick, Murray, last week's tour winner Sam Querrey, and two-time French Open finalist Robin Soderling of Sweden.

Federer, Djokovic, and Wimbledon finalist Tomas Berdych head the other side of the draw, which also includes Melzer, Fernando Verdasco and Nikolay Davydenko.

Nadal, dogged last year by knee injuries, is feeling fit enough that he has accepted Djokovic's offer to pair together in the doubles draw.

Former Grand Slam winner Lleyton Hewitt of Australia and Wimbledon marathon man John Isner won't be playing in Toronto due to injury.

Among the Monday matchups featuring two name players are David Ferrer of Spain taking on David Nalbandian of Argentina, with Gael Monfils of France battling Fernando Gonzalez of Chile.
