The game, which Chicoutimi won 5-3, was marred by a huge third-period brawl.
Remparts captain Brent Aubin received a two-game suspension and $1,000 fine while Quebec winger Ruslan Bashkirov was suspended for one game and fined $500 on Tuesday. Both players made obscene gestures toward the crowd in Chicoutimi.
On Monday, Aubin publicly apologized for making the gesture.
Martel and Roy, meanwhile, were involved in an animated shouting match from their respective benches. At one point, Martel took off his jacket and invited Roy to fight. Neither coach ended up leaving their bench.
The league called the behaviour "unnecessary, inappropriate and provocative."
"These incidents are pointless and will not be tolerated," it said in a release.
Officials called the game, which Chicoutimi won 5-3, with 15 seconds remaining in the third period.
In a separate decision Tuesday, the QMJHL imposed a three-game suspension as well as a $500 fine to Baie-Comeau Drakkar defenceman Mathew Menard, who confronted a Remparts player following Friday's game between the two teams.
This is not the first time the on-ice rivalry between the Sagueneens and Remparts has continued outside the rink.
Earlier this year, a Chicoutimi team official filed a police complaint alleging Roy shoved him after a game between the two teams.
The complaint was later withdrawn.
The Remparts and the Sagueneens meet again this Friday in Quebec City.
