Toronto-based natural and organic food company SunOpta has filed a shelf prospectus with the Securities and Exchange Commission.

The filing covers the possible issues of senior debt securities, subordinated debt securities, special shares, warrants to purchase common shares and common shares of SunOpta as may be issued at indeterminate prices.

The securities registered cannot have an aggregate price exceeding US$100m.

This shelf prospectus reinstates a similar prospectus filed in 2003, which had expired.
