That's an interesting question.
I asked my predecessor that question about the role of the PBO. I asked him how parliamentarians felt when he, Jean-Denis, appeared in the media. Did they dislike that? He told me spontaneously that parliamentarians tend to like it, because it gives credibility to an institution. It also helps to demystify government operations, budgets and the state of the economy.
The open budget, a citizens budget, and participation of the public in the budget process is not something, to be honest, that I've given a lot of thought to, because it's still early in my mandate. I'd be interested in hearing more about it.
From my experience, the budget process is very opaque. It's not transparent at all. I know that from having worked on the other side of the budget process. It's a black box that very few people understand, so helping to demystify that and having greater input from parliamentarians and the public is something that's probably worth considering.
Whether that would be slowing down the process, making it easier for decision-makers or not, that's a different issue; however, it's certainly worth looking into that.
