The province has laid charges against Sunrise Propane Energy Group and its directors more than a year after a massive explosion rocked a northwest Toronto neighbourhood.

The environment ministry has charged the company with five offences under the Environmental Protection Act. The province is accusing the company of failing to clean up the site of the blast.

In addition, two directors of the company are each charged with failing to take reasonable care to ensure the company complies with a provincial order.

The charges could carry millions of dollars in fines if there is a conviction.

The directors, listed as Shay Ben Moshe and Valery Belahov, are expected in court on Sept. 17.

A propane tank at the Sunrise plant, located in the Lawrence Avenue and Keele Street area, exploded on Aug. 10, 2008, damaging dozens of homes and killing an employee. A firefighter also died while fighting the intense blaze.

The company was also charged in July by Ontario's labour ministry for violating the Occupational Health and Safety Act.

Toronto also announced it is suing Sunrise after more than $1 million was spent to clean up the surrounding area, provide adequate fire services plus related public health costs.

More than 1,000 people had to be evacuated after the explosion released asbestos into the air.
