The two were arrested after police executed a search warrant a year ago on a Penticton home that was under surveillance for allegedly being involved in the local drug trade.
Along with illicit drugs, a number of guns were also seized.
The small arsenal of weapons included two revolvers, a fully-loaded semi-automatic assault rifle, a 9mm handgun, a .38-calibre handgun, a homemade-style shotgun and a crossbow.
Crystal Olson, 41, and Andrew Hardenstine, 39, have pleaded not guilty and have been ordered to stand trial in B.C. Supreme Court.
Hardenstine has been the subject of police investigations in the past.
