Search for your company in Thomson One (note:works only in Internet Explorer). Click on the Share Ownership tab that provides information on the top ten shareholders.
Yahoo finance also contains shareholder information. It's listed in the sidebar under the heading ownership.
To look at the actual filings for U.S. companies, you can search in EDGAR and limit your search to Ownership Forms 3, 4, and 5 only.
