Four companies were fined $1.7 million in connection with a week-long fire that engulfed a waste transfer station nearly four years ago in Vaughan, the Ontario Ministry of the Environment said Thursday.

Three men were also sentenced to jail, the Environment Ministry said in a news release. The sentencing was handed down Thursday by Justice of the Peace Linda DeBartolo at the Ontario Court of Justice in Richmond Hill, Ont., near Toronto.

Following an investigation, environment ministry officials laid charges against four companies and three men, who were all convicted last year of violating the Environmental Protection Act.

The defendants owned or operated the site that processed non-hazardous, solid industrial and commercial waste, the ministry said. The disposal site caught on fire in October 2004, affecting neighbourhood homes and schools.  

Robert Sansone and Edmon Hanna received six months in jail and were each fined $5,000. Guido Titton was sentenced to three months and fined $3,000, the ministry said.

Rail Cycle Inc., 2020780 Ontario Ltd. and 2020700 Ontario Inc. were each fined $400,000, while 310 Waste Ltd. was fined $500,000. They have been given 60 days to pay the fine, the ministry said.
