Consider the benefits..
Natural gas has an enviable safety record! Natural gas is non-toxic, and lighter than air which allows it to dissipate rapidly in well-ventilated areas. When used properly, it is one of the safest and most convenient energy sources.
Despite being naturally odourless and colourless, a gas leak is highly detectable due to the chemical odourant called "mercaptan" that is added to it, for increased safety. The industry is very closely regulated. Licenced Gas Technicians are held to rigorous standards. They are well trained, and audited regularly by the Technical Standards and Safety Association to ensure proper adherence to the Ontario gas code.
Natural gas is an extremely clean burning fuel, producing very few emmissions. When burned cleanly, natural gas releases heat, water vapour and carbon dioxide.
Coal, oil and wood on the other hand, release a variety of potentially harmful chemicals into the air when burned, as they are far more chemically complex. When natural gas replaces other fuels, greenhouse gas emissions are significantly reduced.
According to Enbridge Gas, "over the past five years, natural gas has been about 63 per cent less expensive
than electricity and about 64 percent less expensive than oil".
Consider also that electric heating, which is generated from coal or other fossil fuels, is only 30 percent efficient.
Natural gas heating by comparison, is 94 percent efficient!
