Improperly Done Work Resulted in Homeowner Fainting from Carbon Monoxide Leak
March 28, 2023 – The Technical Standards and Safety Authority (TSSA) recently successfully prosecuted Zlatko Antonov of Jolanta Plumbing & Mechanical Inc. for altering exhaust venting on a natural gas boiler without holding a TSSA gas technician certificate. The improperly done work resulted in a carbon monoxide (CO) leak and injury to a homeowner.
Three days after Antonov performed the work at a Toronto residence, the homeowner fainted, and 911 was called. When the first responders arrived and detected a high CO reading, the home was evacuated, and the homeowner was taken to the hospital in an ambulance.
Antonov has never held a TSSA certificate and had a prior conviction for working without a certificate. Given the severe danger posed by Antonov’s unauthorized work and his previous conviction, the Ontario Court of Justice ordered Antonov to pay a $30,000 fine, plus a victim surcharge, within 180 days.
“A fine of this magnitude sends a clear message to Antonov and those participating in the underground market that performing fuels work without a TSSA certificate is a serious violation of Ontario’s public safety laws and will not be tolerated,” said Sam Sadeghi, Director of TSSA’s Fuels Safety Program.
TSSA reminds the public that all gas appliance work must be performed by a TSSA-certified technician who is employed by a TSSA-registered contractor. All Ontario contractors are listed on the TSSA website.
Throughout Ontario, the Technical Standards and Safety Authority (TSSA) administers provincial safety regulations and enhances public safety. TSSA regulates the safety of amusement devices, boilers and pressure vessels, elevating devices, fuels, operating engineers, and ski lifts. Its range of safety services include public education authorization, engineering design review, inspections, investigations, compliance support, enforcement, and prosecution activities.
