So why is he doing this? Simple; To divert our attention away from his monumental failure to diversify the economy, away from his singular vision of making Canada "an energy superpower." Now that oil prices have tanked, it has revealed that vision to be one that not only has harmed the environment, but the economy, as well.
Instead of having "clean, green" jobs to turn to (thanks to Harper's neglect of the solar and wind sectors), many of those laid off in the oil patch are having to go half way round the world to find similar jobs, the only kind they know how to do, just to put food on the table.
