Second seeded Prannoy was stunned by South Korean ninth seed Jeon Hyeok Jin, who won 17-21, 21-14, 21-13 in an hour and a minute on Thursday to enter the quarter-finals of the $65,000 event.
The third seeded pairing of Manu and Sumeeth got the better of South Koreans Choi Solgyu and Jae Hwan Kim 21-17, 17-21, 21-13 in 45 minutes at the Canada Olympic Park.

Mixed doubles second seeds Pranaav and Sikki took just 26 minutes to brush aside the Dutch pair of Robin Tabeling and Cheryl Seinen 21-11, 21-17.
Pranaav and Sikki will meet South Koreans Kim Won Ho and Shin Seung Chan in the semi-finals on Friday. Kim and Shin defeated Australian sixth seeds Sawan Serasinghe and Setyana Mapasa 21-18, 21-10.
