The Mounties called in their national security unit to handle the case after initially hearing the stolen material was going to be smuggled into the United States for possible terrorist or criminal activities.
Police said they now believe the C$50,000 ($37,000) worth of explosives were to be used for criminal activity in British Columbia, where gangs have been fighting a turf war for the province's lucrative marijuana growing business.
The explosives were recovered in raids last week in several towns around Vancouver. A Coquitlam, British Columbia, man is charged with possession of explosives and several others are being held in custody for questioning.
