21:00 CET - Hello and welcome back to some more must-watch quarter-final action from Montreal and Toronto.
First up tonight sees Madison Keys take on the in-form Clara Tauson from 00:00 CET in a fascinating clash.
Keys might have the ranking advantage, but Tauson is on the back of the biggest win of her career against last month's Wimbledon champion, Iga Swiatek. The fact of the matter is this one can go any which way.
That match is followed by an intriguing encounter, again hard to call, between two players looking to return to the top of tennis as Elina Svitolina faces Naomi Osaka.
Follow both Montreal quarter-finals here.
There is also the small matter of ATP quarter-final action in Toronto as world number four and second seed Taylor Fritz takes on Andrey Rublev in a match between two top players struggling to find their best form.
Can a win tonight ignite some much-needed confidence inside one of these two ahead of the US Open later this month?
Following that quarter-final is a match very hard to call between world number seven Ben Shelton and world number eight Alex De Minaur. After beating Frances Tiafoe in the last round, Minaur now sets his sights on knocking out another top 20 player from the States.
