Correctional Service Canada (CSC) reported that staff at Atlantic Institution confiscated contraband valued at about $70,000 earlier this month.
CSC said the seizure happened on November 15 at the maximum-security federal prison in Renous.
Items included THC, tobacco, cell phones and accessories, along with handmade stabbing weapons.
CSC said police have been notified, and the institution is investigating.
The agency noted it uses tools such as ion scanners and drug-detector dogs to prevent drugs from entering its facilities.
They are also heightening measures to keep institutions safe and secure, and work with police to take action against those who attempt to bring in contraband.
CSC also highlighted its toll-free tip line, 1-866-780-3784, which allows callers to anonymously share information about activities related to security at federal institutions.
