Initial Public Offering of Opta Minerals Inc.

TORONTO--(CCNMatthews - Feb 17, 2005) -

SunOpta Inc. (SunOpta) (NASDAQ:STKL)(TSX:SOY) today announced that its
subsidiary, Opta Minerals Inc. (Opta Minerals) (TSX:OPM), has completed
its previously announced initial public offering led by Loewen,
Ondaatje, McCutcheon Limited and a syndicate of underwriters that
included First Associates Investments Inc. and Canaccord Capital
Corporation. Pursuant to the initial public offering, an aggregate of
4,500,000 units of Opta Minerals were issued and sold to the public at a
purchase price of $4.00 per unit, for aggregate gross proceeds of
$18,000,000. All figures are in Canadian dollars.

Each unit consists of one common share of Opta Minerals and one-half of
a common share purchase warrant. The common shares are listed on the
Toronto Stock Exchange (TSX) under the symbol "OPM" and began trading
today. Each whole warrant is listed on the TSX under the symbol "OPM.WT"
and entitles the holder to purchase one common share of Opta Minerals at
a price of $5.00 any time on or before February 17, 2007.

The underwriters have been granted an over-allotment option to purchase
up to an additional 450,000 common shares of Opta Minerals at a price of
$3.99 per share and up to an additional 225,000 warrants at a price of
$0.01 per each one-half warrant. The over-allotment option is
exercisable at any time on or before March 19, 2005 for the purposes of
covering over-allotments, if any, and for market stabilization in
connection with the offering.

Opta Minerals was previously a wholly-owned subsidiary of SunOpta Inc.,
a public company listed on both the TSX and the Nasdaq Small Cap Market.
Immediately prior to the closing of the offering, SunOpta completed an
internal reorganization of its corporate and capital structure pursuant
to which all of its interest in the assets and subsidiaries comprising
its Opta Minerals Group was transferred to Opta Minerals. SunOpta will
retain 72.7% of the outstanding common shares of Opta Minerals prior to
the potential exercise of the over-allotment option.

The common shares and warrants sold pursuant to the offering have not
been, nor will they be, registered under the United States Securities
Act of 1933, as amended, and such common shares and warrants may not be
offered or sold within the United States or to, or for the account or
benefit of, U.S. persons absent registration or an applicable exemption
from U.S. registration requirements. This press release does not
constitute an offer to sell, or the solicitation of an offer to buy,
common shares or warrants of Opta Minerals in the United States.
