EDMONTON — Alberta is the best province in Canada. Despite relentless efforts by the federal government to kill the oil and gas industry, the province remains the wealthiest (per capita) in the country. The fact that energy companies earn growing, often record profits is not, as Liberal boosters claim, evidence that Ottawa is not targeting Alberta. It is, instead, evidence that markets find a way, and a reminder of how much more wealthy all of Canada would be if the federal government just ended its onslaught.
