TORONTO: The Canadian Taxpayers Federation (CTF) today is calling on the McGuinty government to clarify its position on imposing new carbon taxes in Ontario. It is widely reported that Premier McGuinty and Ontario Environment Minister, John Gerretsen favour a cap-and-trade system as a 'first choice'. CTF Ontario, Kevin Gaudet, said, "cap-and-trade is a carbon tax, just under another name. When and how does he plan to unleash this new tax on Ontarions? What happened to his campaign promise not to impose new taxes?"
