Residents of the northwest Toronto neighbourhood ravaged by the explosion and fire at a local propane facility met with lawyers Sunday to join a class-action lawsuit.

Hundreds of residents gathered at a midtown hotel Sunday to ask lawyers about what compensation they may be entitled to.

Exactly one week ago, explosions and a massive fire rocked Sunrise Propane, which is situated in a residential neighbourhood in the Keele Street and Wilson Avenue area.

Several hundred residents were evacuated and were slowly allowed back into their homes throughout the last week.

Many of them joined the lawsuit at the urging of the team of lawyers at today's meeting.

"This lawsuit is about understanding what you have been through, advocating for you and ensuring justice is done and your stories are told," lawyer Richard Bogoroch said.

Lawyers admitted that it could be months before the case gets to court and years before residents receive any compensation.

The city of Toronto took over cleanup duties in the neighbourhood after the company was deemed to be responding too slowly.

Workers in protective clothing spent a second day in the community Sunday, picking up debris and testing the air for asbestos.

Many residents are afraid that their homes are unsafe for them to live in and worry about the potential long-term health effects of the fire.

"I am not safe in my own home," Luigi Vilardo told CTV Toronto. "How do you compensate for that?"
