Police in Toronto, the surrounding region, and across Ontario cracked down on two rival street gangs in a series of raids that began around 5:00am Wednesday.
Cash, 10 firearms, cocaine, heroin, and marijuana were seized during the raids.
50 people were arrested and charged.
30 others were taken into custody over the course of the investigation, which police say began last year.
Authorities say the 'Asian Assassins' and the 'Sick Thugs' are responsible for a number of shootings and allegations are they involved in the drug trade.
The busts were a joint effort between Toronto Police and other officers from the OPP, Brantford, and Windsor.
