TORONTO -- Ontario's top court has ruled the federal government's carbon charge is constitutionally sound.
In a split decision, the five-judge panel rejected a challenge from Premier Doug Ford's government to the validity of the carbon-pricing law.
Ottawa maintains it had to act to deal with the urgent threat of climate change as an issue of national concern.
The federal government said its approach -- imposing a levy on gasoline and fossil fuels -- respected provincial jurisdiction.
Ontario and three other provinces argued the Liberal government under Prime Minister Justin Trudeau overstepped its authority in imposing the charge.
Last month in a split decision, the Saskatchewan Court of Appeal sided with Ottawa in a similar challenge.
