The reigning world champions faced Switzerland’s Nina Betschart and Tanja Huberli as they looked to reach the last eight.

Humana-Paredes and Pavan won the opening set 21-12, but their rivals hit back by taking the second 21-15.

The final set saw the Canadian team regain control and ultimately clinch the decider 15-7.

"It has been an up-and-down couple of days, that’s for sure, and that’s to be expected at the end of the season," Humana-Paredes said.

"At this point it’s just about surviving and giving everything, you’ve got.

“It’s been a long season, you can see it’s wearing us down but at this point it’s survival of the fittest and it’s whoever wants it more, who has the heart."

Humana-Paredes and Pavan will now face fourth seeds Agatha Bednarczuk and Eduarda Lisboa.

The Brazilians were comfortable 21-16, 21-13 winners over Marta Menegatti and Viktoria Orsi Toth of Italy to progress to the quarter-finals.

Germany’s Margareta Kozuch and Laura Ludwig were also among the winners today, overcoming the Kelly Larsen and Emily Stockman of the United States 16-21, 21-16, 15-12.

Norwegian pair Anders Mol and Christian Sørum needed three sets to reach the men's quarter-finals.

The duo fell a set behind to Germany's Nils Ehlers and Lars Flüggen but responded impressively to claim a 15-21, 21-15, 15-11 win to reach the last eight.
