When Parliament resumes sitting April 16 after a two-week Easter break, its first order of business will be a vote on the Conservative government’s Clean Air Act, which has been greatly amended by the opposition parties.

It’s uncanny how two “former” climate-change deniers can use all their old anti-Kyoto arguments even as they claim to support the treaty. But the prevarication that worked three years ago didn’t work yesterday, and critics are roasting Baird and Harper.
