"OTTAWA - Canada on Monday imposed a landmark carbon tax on four provinces which had defied Ottawa’s push to combat climate change, prompting unhappy premiers to say they would challenge the measure.
Prime Minister Justin Trudeau, citing international commitments to fight global warming, had made clear for two years he would slap the tax on any of the 10 provinces that did not come up with their own plans by April 1.
The measure is opposed by Ontario, the most populous province, where Trudeau’s Liberals need to do well to stand a chance of retaining power in a federal election this October."
