The Financial Post reports in its Wednesday, Nov. 1, edition that Mark Carney has questioned the federal government's move to lift the carbon price on home heating oil. A Canadian Press dispatch to the Post reports that Mr. Carney, long rumoured to be a possible future Liberal leadership candidate, says he would have looked for other ways to provide financial support to Canadians. However, Mr. Carney, the UN special envoy on climate action who was speaking at a net-zero conference in Ottawa, also says no other government and prime minister in Canadian history has done more on climate and he applauds parallel moves to help households transition to greener heating alternatives. Prime Minister Justin Trudeau's announcement last week to increase the carbon price rebate for rural Canadians and lift the price on home heating oil for the next three years marks the first time the Liberals have retreated on their carbon pricing policy. Affordability concerns have hit the party's polling numbers in four Atlantic provinces, where about 33 per cent of homes still use heating oil, a far higher proportion than the rest of Canada, but Mr. Trudeau has denied the pricing change was about saving Liberal seats.
