Police raided three locations suspected to be involved in the production of synthetic drugs early on Friday morning.
One bust took place in a L'Assomption warehouse in the city’s industrial district while the others were in St-Charles-Sur-Richelieu and a rental storage business in Brossard.
The operation involved officers from the SPVM, Surete du Quebec, L'Assomption and Longueuil police and American border police.
No arrests have been reported and the type of drugs being made is not yet known. Several of the officers involved in the busts were dressed in hazardous material equipment.
Police would not confirm if the raids were connected to an operation in Ontario on Thursday that resulted in 18 arrests following an 18-month long investigation.
