After discovering a clandestine meth lab, police in Brampton temporarily forced dozens of people out of their homes on a quiet residential street.

Halton Regional Police said the bust was one of three warrants executed across the GTA by its drug squad on Thursday night, in cooperation with several other police forces including Peel Regional Police and the Ontario Provincial Police.

Firefighters also helped dismantle the crystal methamphetamine lab located inside a large brick mansion on Midsummer Drive near Cottrelle Boulevard in an upscale part of Brampton that's also close to a playground.

Halton Staff Sgt. Brad Murray blasted those behind the meth lab for having "no regard for human life" and exposing neighbours to potential danger.

Peel police tweeted that 10 homes were evacuated around 8 p.m. for public safety reasons, but residents have since been allowed back into their homes.

Officers in hazardous material suits pulled several rubber bins worth of evidence from the home and Halton police's drug squad later posted an image of four containers filled with drugs.

Murray said in total, officers found between five and six kilograms of meth.

Halton police said three men and two women were arrested in connection with the busts, including one man who tried to flee from police.

The other drug-related warrants were executed in Toronto and Vaughan, though neither location contained a drug lab.

Police said the investigation is ongoing and they'll be back on the scene to continue taking apart the lab tomorrow morning.
