It's no different from what exists for candidates or parties in that regard. Audits always take place after the fact, so I am not sure how we can cure that, except eventually moving towards a system in which we have real-time disclosure of contributions. Technology probably allows for that. I'm not sure it can be done. Elections Canada would have to answer that, but it's doable and you could verify a contribution amount and sources in real time, with an address. That can be achieved.
