The Canadian contingent is growing at the National Bank Open presented by Rogers.
Canada's Duncan Chan, ranked 601st in the world, upset world No. 90 Hugo Gaston of France, 2-6, 7-5, 6-3, on Saturday in Montreal to qualify for the men's main draw.
Chan is entering his senior season at Texas Christian University, where he was named the most improved player in NCAA men's tennis this past season.
The native of Markham, Ont., was one of only two players to finish the NCAA season ranked in the top 10 in both singles and doubles after helping TCU reach the national semifinals. He also was named an All-American.
Chan joins fellow Canadians Felix Auger-Aliassime, Denis Shapovalov, Gabriel Diallo, Liam Draxl and Alexis Galarneau in the main draw, which starts Sunday.
All other Canadians lost in qualifying on Saturday.
On the women's side in Toronto, hometown player Ana Grubor fell just short of a major upset, falling 3-6, 7-5, 7-6 (7) to No. 1 qualifying seed Maya Joint of Australia.
Familiar names to advance included Greece's Stefanos Tsitsipas and 2024 NBO champ Alexei Popyrin of Australia on the men's side, and Sloane Stephens of the U.S. on the women's side.
