Eleventh-seeded Andrea Petkovic defended her place in the competition by winning 6-2, 6-2 against native-Canadian Eugenie Bouchard in 79 minutes.
The wildcard pushed the German with 10 attempts on her serve; however, Petkovic saved eight break points and broke her opponent six times from 11 opportunities.
Today’s match was a good start to the tournament for Petkovic, who entered the top 10 for the first time this week.
Ana Ivanovic, who was supposed to play Venus Williams in the first round, got on court after the German and beat qualifier Zhang Shuai in a short 55 minute match, 6-1, 6-1. Ivanovic, a former No. 1, hit six aces and won 91 percent of her first-service points.
Flavia Pennetta took a win while her doubles partner, Gisela Dulko, lost.
Pennetta defeated Maria Kirilenko 6-3, 6-1. Both hit many double faults with the Russian leading with one more at nine total, but the World No. 25 from Italy won 80 percent of her first-serve points.
The Italian now leads over the Russian 5-2 in their head-to-head series while moving on to the second round.
Daniela Hantuchova took Dulko out with a 6-3, 6-4 win to improve her record to 41-31 over the last 12 months.
Hantuchova took advantage of the Argentine's serve four of five times and hit two aces.
Australian Jelena Dokic had to retire to Bojana Jovanovski at 2-0 in favor of the Serbian. It was better luck for the qualifier, who had some travel issues last week that didn't transfer to Canada.
The other upsets included Yanina Wickmayer, who lost to Roberta Vinci of Italy 6-4, 6-2.
