Of course the definitions are slippery. However, Alberta not only has the lowest taxes in Canada, it has among the lowest taxes in North America. The Fraser Institute’s index of economic freedom, which ranks all Canadian provinces together with American states, has all Canadian provinces dead last - except for Alberta. Alberta is actually higher on the list than more than half of American states. The index measures taxes and regulatory burdens.
When the Iraq war was starting, popular opinion in Canada was dead set against it - except in Alberta, where the war was more popular than it was in the U.S. overall.
When measuring attitudes against America, and against Republican presidents, Alberta has always been a pretty big outlier - by far more pro-American and pro-Republican than any other province.
In yesterday’s election, the Alberta PCs won 86% of the vote, and all the other parties combined got 14% of the vote.
Of course, Albertans support public health care, so it’s not exactly a libertarian oasis, but still… on balance I’d say that the record shows we are very conservative.
