RCMP say they found what was likely crack cocaine alongside drug paraphernalia, bear spray, and more than $7,500 in cash at an Inuvik home.
David Hevia, 27, was arrested on Saturday after RCMP carried out a search warrant.
Hevia faces charges including drug possession, multiple weapons charges, and not complying with his probation order.
He is being held in custody and will appear in court on January 23 in Yellowknife.
Police said they are not looking for any other suspects.
