142 officers raided more than a dozen homes Wednesday morning as they looked for the chief of operations for the motorcycle gang and his second-in-command, who are believed to be in Lotbiniere.
Police are also targeting members in Thetford Mines and Becancour.
Two Montreal met were arrested last week and charged with cocaine possession with intent to traffic.
The 34 people arrested Wednesday are expected to appear in court via videoconference.
