Drugs and other contraband items valued at $604,000 have been seized at Bowden Institution.
The materials seized June 13 included methamphetamine, THC, cellphones, cellphone chargers, earbuds and DVD remote controls.
Police have been notified and the institution is investigating, Correctional Service Canada said in a release Wednesday.
In March, drugs and two cellphones with a estimated value of $384,000 were seized at the same prison.
The agency says it has increased measures to prevent contraband from entering its institutions to help ensure a safe and secure environment.
“CSC also works in partnership with the police to take action against those who attempt to introduce contraband into correctional institutions,” says the federal agency.
It uses a number of tools to prevent drugs from entering its facilities, including ion scanners and drug-detector dogs to search buildings, personal property, inmates and visitors.
