Canada’s national carbon tax on consumer fuels is likely in its final weeks after both major contenders to replace Prime Minister Justin Trudeau as Liberal leader have promised to scrap it.

Liberal leadership candidate Mark Carney says he will abandon his party's consumer carbon tax and replace the policy with an incentive program that rewards Canadians for making green choices.

Mark Carney says that the carbon tax “isn’t working and has become too divisive” and has pledged to cancel it immediately and replace it with a “new approach that leaves Canadians better off, while reducing our emissions,” if he is chosen to replace Justin Trudeau.

Liberal leadership hopeful Mark Carney says – if he were to become prime minister – his government would 'immediately remove' the consumer carbon tax and replace the policy with an incentive program to 'reward Canadians for making green choices.
