The tournament started on Saturday with qualifying matches played over the weekend. A total of 56 players are competing in the main draw starting today, including 39 direct entries based on the players' WTA rankings, 19 qualifiers and 5 wild cards. The players include 16 seeds, selected from the WTA' s top 18 players.

In a rather surprising turn of events, four seeded players, out of five who competed today at Rexall Centre on the campus of York University, fell to their lower-ranked rivals.

In the featured evening match, former world No. 1 Jelena Jankovic was soundly defeated by Julia Goerges of Germany, 6-1 and 6-3. Jankovic, Serbia' s most favorite athlete and a frequent doubles partner of Li Na, is the No. 15 seed in this event.

The biggest upset, however, came earlier in the afternoon, when 135-ranked Galina Voskoboeva of Kazahkstan overcame Marion Bartoli of France, the No. 9 seed. After the match, a beaming Voskoboeva told reporters that she has played "pretty' successfully this year, after staying off the tournament circuit last year due to an injury, and was "pretty confident" in today' s match.

The other two seeded players who went down in defeat were No. 12 Svetlana Kuznetsova and No. 14 Anastasia Pavlyuchenkova, both of Russia.

Kuznetsova fell to 19-year-old Simona Halep of Romania, one of only three teenage players in this year' s tournament; while Pavlyuchenkova conceded to Maria Jose Martinez Sanchez of Spain.
