Seven people have been arrested in what police are calling an elaborate ketamine production and trafficking ring in the Toronto area.

Police say they raided 10 homes in Toronto and Markham on Thursday and seized more than 60 kilograms of ketamine as well as more than $300,000 in cash.

They say two of the homes have been quarantined as suspected drug labs and are scheduled to be dismantled over the next two days.

Six of the suspects -- a woman and five men -- are charged with conspiracy to produce ketamine, production of ketamine, drug possession for the purpose of trafficking and possession of property obtained by crime.

Another woman is charged with drug possession for the purpose of trafficking and possession of property obtained by crime.

Police say the investigation is still in its early stages.
