Right now, Canadian Prime Minister Stephen Harper's Conservative party are blanketing the airwaves with a US-style attack ad campaign against NDP leader Thomas Mulcair.
In one of the ads the very serious voice-over tells us that “according to experts Mulcair's carbon tax will raise gas by 10 cents a litre.”
A little research finds that the “experts” in the ad, are in fact a singular expert named Jack Mintz, who in a news release correcting a tweet he made in April of last year estimated that the NDP carbon tax plan, put forth by the now-deceased NDP leader Jack Layton, not Mulcair, would result in a gas price hike of 10 cents a litre.
Interestingly enough Jack Mintz sits on the board of directors of Imperial Oil Canada, which is owned by ExxonMobil. Regular readers of this site know that ExxonMobil has a long and sordid history when it comes to attacks on climate change science and policy.
