If you mean the difference between soliciting and non-soliciting, the bill actually does give only minimal standards. There are only five differences between soliciting and non-soliciting corporations.
Soliciting corporations have to have three directors instead of one; non-soliciting can have one. The audit requirements are a little more onerous for soliciting corporations simply because there's a public policy reason involved: they collect money from the government or the public, so there's a public interest in what they actually do with that money. They cannot have a unanimous members' agreement, soliciting corporations, which is not something that may happen very often, but it's forbidden for them. There's a difference in what they do with the funds upon dissolution, which again won't affect them on a day-to-day basis until they actually do dissolve. And the financial statements have to be filed with Corporations Canada. It's not really that much of a difference between the soliciting and the non-soliciting.
The various categories for audit requirements is maybe what you're referring to. But the requirements are minimal. Under $25,000 there's no need for an audit at all, and they can decide not to do that. Between $25,000 and $50,000, is it...?
