Rybakina won 5-7 6-2 7-5 in two hours and 33 minutes to set up a last-eight clash against another Ukrainian opponent in Marta Kostyuk.
Both players converted break points midway through the first set before Rybakina saved two set points, only for Yastremska to take the opener two games later.
Ninth-seed Rybakina seemed to kick into gear in the second, holding her serve while breaking Yastremska twice to force a decider.
With the third set evenly poised at 5-5 after a break for each player, Rybakina broke Yastremska once more to have the opportunity to serve out for the match.
Rybakina went 0-30 down in the crucial game before eventually converting her fourth match point to secure the win in Montreal.
