Unfortunately the article associated with the photo failed to mention the libertarian presence instead it spoke about the rise of social conservatism in Canada. Libertarians are not social conservatives, on the contrary the libertarian attitude is extremely liberal in that regard.
The article's author Paul Wells, seems to be saying that there are dangers in a Harper Conservative government because it still carries along the baggage of social conservatism the so-called "hidden agenda". I agree, and of course as the Canadian electorate ages (especially the Boomers) both fiscal and social conservative attitudes rise. This attitudinal shift was illustrated in the article by pollster Allan Gregg.
This creates opportunities for Libertarians in Canada. Libertarians demand fiscal restraint on government while simultaneously advocating the traditional "Canadian" attitude of social liberalism. To paraphrase Pierre Trudeau, the government does not belong in the bedrooms of the nation, or any other room for that matter.
