Wasn't Fantino quoted as saying something along the lines of "We weren't seeing enough results"? As if the 280k for 2010 and 2012 is somehow hurting the books more than the million they recently wasted on that Religious Freedoms office.
This is actually typical of nominally fiscal conservatives around the world: Use a "Death by 1000 cuts" to cut a bunch of tiny programs that progressives like but that you roll your eyes about, use very rational terms to justify cuts on performance or fiscal basis.
It took Harper about, I dunno, 2 weeks from his first PM mandate to start on that kind of thing. They cut the prison tattoo safe needle program, which costed something like $1 million a year and actually had a net negative cost because the medical bills it prevented (to say nothing of the human cost of HepC) exceeded the cost. From a fiscal standpoint it's small potatoes and irrelevant. But if you approach it from "Harm reduction is intellectually bankrupt, bad people need to be punished", then it's a perfectly logical cut.
Then the Court Challenges Program. That was the program that the feds funded for groups to be able to file charter violation lawsuits against the government in order to a) establish a body of jurisprudence on major charter issues, and b) ensure that active steps were taken to maintain equity in Canada. I think the cost was around $10 million a year or so? In terms of the number of cases it funded, it was fairly cheap, and when you think about it, a brand spanking new constitution needs a lot of court exposure to bang out the key issues and really get a sense of what our obligations actually are, under the charter. But what it comes down to is that Harper's chief of staff was Ian Brodie, and his PhD thesis was basically "Feminists and leftist activists want to use the court to overthrow Real Canada and replace it with a hippie paradise, and the court challenges program enables this" and "The government doesn't pass unconstitutional laws, so why should we pay people to challenge them?" and Ted Morton weighed in too--you can very clearly see who has the Prime Minister's ear and what their advice was--and the program was cut.
Flash forward a few years. PromArt is cut. Is it a huge expenditure? No, and especially not if you take into account the way that cultural expenditures redistribute themselves through the economy and boost employment. So, fiscally, not a big deal. But if you approach it from "The government gave money to a band that has the word 'Fuck' in their name. Those lefties and their anti-God anti-Values art need to be cut off." then it's a perfectly logical cut.
I can't for the life of me figure out how drought prevention is at odds with anything, but same thing there. I would guess it's a reflection of broader skepticism of international law, the United Nations, multilateralism, etc in favour of "doing the right thing", "you're with us or against us", closer ties to the US and an American approach to international issues, etc. It's not about the cost, it's about the symbolism of the convention. I'm sure there are analysts more clued in to international law who can better assess Harper's record on it.
Ditto closing Status of Women and having Bev Oda saying "Women are equal, case closed". Ditto the religious freedom thing you mention. In each case, the public justification was primarily fiscal and about good fiscal stewardship, but in each case there's an implicit or explicit "but, while we're talking about it, we also don't agree with the idea of these programs"
Obviously it's the government's prerogative and there's nothing illegitimate about the cuts--and in fact depending on your perspective some or all of them might be a good move. I don't really have any desire to debate the wisdom of any individual cut or the government's approach as a whole. The Court is really the only issue of the above that's directly something I'm interested in. I just want to highlight that the public fiscal justification ("good value", "bad value", "can't afford", "necessary expense") of some of these cuts or spending is actually a veneer for an intellectual, philosophical objection to the programs on the part of the government.
They didn't withdraw from the drought treaty because of the piddling cost obligations, they withdrew from it because they didn't like something about the obligations it placed on Canada or the symbolism of it.
