Prohibiting donations from anyone is a bit of slippery slope, because government is telling private organizations what they can use their money for. However, given the constant whining on this topic, I think it should be implemented and we can see if the promised utopian voting structure will develop. I am skeptical because the problem today is that no party can get elected without promising to splash money around as if there are endless amounts available. I don't think that will change by restricting donations.

On the leadership contests, this is a slippery slope. It means heading down the US road of people being "registered" Liberals, Conservatives, Village Idiots, er, the NDP, etc. Not sure that a couple of cats voting is enough reason to change-my cats vote all the time. As for restaurants being the address of a party member, lots of people get their mail directed to their business. Many self employed people spend a lot of time at their business (and for the benefit of the public sector union types, that is not 8-5 M-F).
