The Toronto Police Service (TPS) said they have made the largest cocaine bust in the city's history.
Police on Wednesday said they seized 835 kilograms of cocaine with an estimated street value of $83 million.
Dubbed Project Castillo, the months-long investigation has dealt a major blow to organized crime, police said.
Police Chief Myron Demkiw said the drugs were sourced from the Jalisco New Generation Cartel in Mexico.
Police said of the amount they found, 475 kilograms were seized in a single truck crossing at the Canada-U.S. border.
Demkiw was joined on Tuesday by Superintendent Paul MacIntyre of the TPS's organized crime enforcement division, Solicitor General Michael Kerzner and members of the TPS Drug Squad.
Police said six people have been arrested, including four Canadians and two Mexican nationals.
Three other suspects are still being sought, one in Niagara Falls, Ont., and two who police believe may have fled back to Mexico.
“Taking these drugs off our streets prevents violence, protects lives, and dismantles dangerous criminal networks," Chief Demkiw said. "This impact is only possible through the dedication of our members and the invaluable collaboration of our partners.”
'Criminal networks'
"Investing in police pays off,” said Solicitor General Kerzner.
"Thanks to exemplary work by our police officers, they're exposing and dismantling these dangerous criminal networks and holding those responsible accountable for their illegal activities."
Jorge Luis Mundo Garcia, 31, and Jimenez Avila Rodolfo, 28, both Mexican nationals, were arrested and charged with possession of a Schedule I Substance for the purpose of trafficking, and possession of proceeds of crime under $5,000.
