Sania Mirza overcame a second set laps to beat local wild card Heidi El Tabakh and move to the second and final qualifying round of the WTA Rogers Cup.
Seeded 11th in the qualifying event, Sania dispatched the Canadian 6-0, 4-6, 6-0 after one hour and 42 minutes.
The Indian will next face Germany's Kathrin Woerle, who defeated Russian Alla Kudryatseva 6-2, 7-5 in her opening round.
Sania made a strong start and was all over her opponent but surrendered her serve thrice in the second set to let the local player make a comeback.
However, she again regrouped and blanked Heidi in the decisive third set to move to the next stage.
