Globe editorial: Doug Ford wants to loosen emissions rules for industry. Ottawa should say no - 2020-02-06
Ontario is now trying to persuade the federal government to exempt its industries from the tax, and allow the province to replace it with a made-in-Ontario version.
Ottawa did exactly that in Alberta last December, when it approved that province's industrial carbon tax. Alberta's system is not quite as robust as the federal rules, but the Trudeau government deemed it close enough and signed off.
Ontario's rules, however, are not close enough.
