Two men have been charged with production of an illegal substance after New Brunswick RCMP found a drug lab in Lac-Baker, N.B.

Daniel Cozak, 66, and Charles Cozak, 26, from Quebec City were charged Wednesday morning after police searched their home.

Police say they found a sophisticated, industrial scale lab. They believe the lab had the ability to produce 1.5 million pills of ecstasy.

A 55-year-old woman and a 24-year-old man were also arrested in Quebec as part of the joint investigation.

The men appeared in Grand Falls Provincial Court Wednesday. Both men remain in custody and will be transferred to Quebec.

RCMP have seized the lab and are currently dismantling it.
