An Ontario company convicted in a deadly explosion of a propane plant in Toronto will be back in court Dec. 9 for sentencing.

Sunrise Propane and directors Shay Ben-Moshe and Valery Belahov were found guilty last month of nine provincial-offences charges in relation to the 2008  blast that killed one man and forced thousands of people from their homes.

Twenty-five-year-old employee Parminder Saini died in the blast and a 55-year-old firefighter, who responded to the emergency call on his day off, also died of a heart attack.

The court ruled Sunrise failed to provide safety training and a safe working environment, discharged a contaminant and contravened a number of provincial orders related to the cleanup after the blast.

The court also found Ben-Moshe and Belahov failed to take all reasonable care to prevent the company from flouting those orders. 

Following the blast, the government shut down all three Sunrise Propane's facilities.
