Dave Kearney, Martin Moore, Eoin Reddan, Sean Cronin, Tadhg Furlong, Darragh Fanning and Luke McGrath each crossed over as Leinster beat their French visitors 50-8 on Saturday.
It keeps them top of the pool, with Wasps just two points back and a trip to the Ricoh Arena on the cards this weekend.
And second row Toner, who was named man of the match against Castres, believes Leinster's can finish the pool stage with a flourish.
"It was good to see everything clicking on the night," said man-of-the-match Toner. "From the first scrum, it's hugely positive to get the confidence boost and then allow the backs to do their stuff.
"Having a full squad to pick from is always a big thing for us. We have moves up our sleeves that we have in training. We know they work and most of them are Matt O'Connor's moves.
"Our past experience will help (away to Wasps). A lot of guys have played well in this competition in the past. Our goal is to go all the way but our primary focus is to firstly get out of the pool next Saturday."
Glasgow Warriors kept their hopes of a place in the last eight alive with a 21-10 victory over Montpellier, DTH van der Merwe the hat-trick hero at Scotstoun.
Gregor Townsend's side, who have conceded just four tries in five European outings this season, face a tricky trip to Bath this weekend knowing victory will throw their name in the hat for the knockout stages.
There were also victories for Zebre, Newport Gwent Dragons and Cardiff Blues, with the latter on Friday night catching the eye.
The Blues ran in 16 tries to bring up a century of points, eventually beating Rovigo 104-12 to keep their qualification bid on track.
Kelly Haimona came off the bench to score his side's only try as Zebre beat Brive 23-13, while a Hallam Amos double helped the Dragons to a 40-29 victory at Newcastle Falcons.
Ospreys and Scarlets could not match the feats of their Welsh counterparts, with the GUINNESS PRO12 leaders losing 20-9 to Northampton Saints and Wayne Pivac's mean going down 40-23 to Leicester Tigers.
Ulster were put to the sword by reigning European champions Toulon, losing 60-22, while there was also no joy for the remaining Irish provinces, Munster beaten 33-10 by Saracens and Connacht slipping to a 24-33 defeat at home to Exeter Chiefs.
Elsewhere, a late Fabrice Estebanez drop-goal condemned Edinburgh to a 21-19 defeat by Lyon and Benetton Treviso were on the receiving end of a 53-7 reverse at Racing Metro.
