There are different rules in the Canada Business Corporations Act for distributing and non-distributing corporations. There are also provincial securities rules that Claire was alluding to. Right now in Ontario, for example, anyone owning over 10% of voting shares is considered an insider under insider trading rules. That's a beneficial ownership. With that information, anything over 10% is disclosed.
The other thing is that under the CBCA, any person can get access to the registered shareholder list of a distributing, that is a public, company in the CBCA. That means any person, subject to the conditions and so on.
