As part of the federal government’s carbon pricing program, a carbon charge applies to fossil fuels sold in Ontario. The federal carbon charge is included on customers’ bills, with the exception of customer facilities that have an exemption certificate issued by the federal government. Large volume customers may be required or eligible to register with the federal government in order to receive full or partial exemption from the federal carbon charge.
