Reigning champion Bianca Andreescu has received a first-round bye for the National Bank Open presented by Rogers.
Tennis Canada released the first-round matches Saturday for the women’s singles event at IGA Stadium in Montreal.
Andreescu, from Mississauga, Ont., captured the 2019 title in Toronto after Serena Williams retired due to injury during the first set of the final. The National Bank Open was not held in 2020 due to the COVID-19 pandemic.
The 21-year-old Andreescu, who is ranked No. 5 on the WTA Tour, holds the No. 2 seed in this year's tournament.
Vancouver's Rebecca Marino will play American Madison Keys and Carolina Zhao of Richmond Hill, Ont., faces Sara Sorribes Tormo of Spain in the first round.
Leylah Annie Fernandez, from Laval, Que., awaits a qualifier for her first-round match. Fernandez will then take on Andreescu should she advance to the second round.
