Major drug seizure in Mississauga, Ont., as police work to shut down meth lab

Following a raid in an industrial area, police say they discovered 80 drums of unknown chemicals, numerous presses and an "enormous amount of ecstasy" pills. Staff Inspector Don Campbell says police will take several days to "neutralize" the volatile site which could spark a fire or explosion.

Campbell says the lab is the work of a "sophisticated organization" and is the largest one he's ever seen.

He says it's not clear if the drugs were destined for the Toronto area or were intended to be exported.

Four people have been arrested and charged with conspiracy.
