Kirsten Flipkens secured the Bell Challenge title with a straight sets victory over eighth seed Lucie Hradecka.
Flipkens has been in great form in Quebec, beating Dominika Cibulkova and Mona Barthel - the first and third seeds - respectively en route to her first WTA final.
She claimed the first set in dominant fashion against Hradecka but was made to work hard in the second before securing the all-important break in the 11th game and holding serve to seal a 6-1 7-5 triumph.
"I played really well and really aggressively in the first set," the Belgian told the WTA's official website.
"I feel my only advantage in the second set was the break at 5-5 - it was a really close match and I was down in a lot of the games I won.
"I have to give credit to her - she came back strong in the second set."
The defeat means Hradecka is yet to win a final in five attempts on the tour, yet the Czech remains upbeat.
"I didn't start well. But all credit to her. It's tough to lose in a final again, but hopefully I can win my next one," she said.
Meanwhile, Briton Hather Watson missed out on another doubles title in Quebec.
Watson, who has already won two WTA doubles events this season, and partner Alicja Rosolska were beaten 7-6 (7/5) 6-7 (6/8) 10-7 by Tatjana Malek and Kristina Mladenovic.
