Ten suspects have been arrested and face a total of 139 charges following the bust last summer of a drug lab south of Calgary.
They are being charged with a variety of offences ranging from fentanyl production to criminal conspiracy.
Police say seven of the accused are from Edmonton and three are from Okotoks.
The Alberta Law Enforcement Response Team says officers seized drugs, weapons, cash and vehicles in one of Canada's largest fentanyl seizures.
ALERT says it seized 13.6 kilograms of fentanyl, 11.9 kilograms of fentanyl precursors, 6.6 kilograms of opioids, 9.9 kilograms of methamphetamine and 7,600 kilograms of chemicals used in fentanyl production.
