Why: The fuel charge is the portion of gas used the get your natural gas down the TransCanada pipeline to Ontario. This price should be clearly stated in any contract you sign, however, if you are buying Ontario landed gas there is NO fuel charge.
Beware: If you are buying Ontario landed gas there should be no fuel gas charge, as it should already be included in the price. IF the contract specifies each component of the price, then ensure the contract includes the exact fuel charge you are expected to pay. Vague language can lead to surprise costs over time.
