Surrey RCMP officers in Port Coquitlam, B.C., busted a massive drug lab on April 19 that police say could produce 39 million fatal doses of fentanyl in just three weeks — roughly matching the population of Canada.

According to a statement from the RCMP, an "illicit fatal street dose" of fentanyl is 2 milligrams and the lab was capable of producing 26 kilograms (13 million potentially fatal doses) of pure fentanyl per week.

Surrey RCMP said it was helped by various federal and municipal police agencies in dismantling and collecting evidence from the lab, which was so big that it took three days to fully break down.

"This drug and chemical seizure has dealt a multi-million-dollar blow to organized crime and gangs in BC; helping attack the income sources of those who put our communities at risk with drug trafficking; and the gang violence that accompanies it," police said in the statement.

Police say no charges have been laid in relation to the lab's operations, but an investigation is ongoing.
