OPTI Canada Inc. Provides Project Update and Files Revised and Restated Year-end 2008 Financial Statements

     TSX: OPC

     CALGARY, June 3 /CNW/ - OPTI Canada Inc. (OPTI) today announced that
progress continues to be made in the start-up phase of the Long Lake Project.
A key milestone was achieved in May 2009 with the completion of the heat
addition to the hot lime softeners (HLS) in the water treatment plant. Bitumen
production for the month was limited as maintenance work was completed on
parts of the SAGD water plant that have been operating for over 18 months.
With the implementation of improvements to the HLS and the completion of the
SAGD water plant maintenance, steam injection to the wells in the last week in
May averaged 95,000 bbl/d. This resulted in average bitumen production volumes
of 17,000 bbl/d over the same period. As of May 31, there were 43 wells on
production.

     Revised and Restated Financial Statements

     OPTI also reported today that it has restated its year-end 2008 U.S.
generally accepted accounting principles (GAAP) reconciliation. The purpose of
the re-filing is to correct the Company's interpretation of the timing of the
commencement of SAGD operations at the Long Lake Project under U.S. GAAP.
Previously, the Company's U.S. GAAP financial statements interpreted the start
of commercial SAGD operations as concurrent with start-up of the SAGD Pilot in
2006. This interpretation has been amended to reflect the start of commercial
SAGD operations as July 1, 2008, the same date as in the Company's Canadian
GAAP financial statements. The impact of this restatement is described in note
14 of the financial statements filed on form 40-F/A with the U.S. Securities
and Exchange Commission.
     The Company's Canadian GAAP financial statements and Management's
Discussion and Analysis were also revised and re-filed to reflect the
retroactive adoption of CICA Handbook section 3064 "Goodwill and Intangible
Assets", effective January 1, 2009. The impact of the restatement is described
in note 2 to the Company's financial statements as filed on SEDAR. These
restatements would have been otherwise required in the Company's 2009 year-end
filings.

     About OPTI

     OPTI Canada Inc. is a Calgary, Alberta-based company focused on
developing major oil sands projects in Canada using our proprietary
OrCrude(TM) process. Our first project, Phase 1 of Long Lake, consists of
72,000 barrels per day of SAGD (steam assisted gravity drainage) oil
production integrated with an upgrading facility. The Upgrader uses the
OrCrude(TM) process combined with commercially available hydrocracking and
gasification. Through gasification, this configuration substantially reduces
the exposure to and the need to purchase natural gas. On a 100 percent basis,
the Project is expected to produce 58,500 bbl/d of products, primarily 39
degree API Premium Sweet Crude with low sulphur content, making it a highly
desirable refinery feedstock. Due to its premium characteristics, we expect
PSC(TM) to sell at a price similar to West Texas Intermediate (WTI) crude oil.
The Long Lake Project is being operated in a joint venture with Nexen Inc.
OPTI holds a 35 percent working interest in the joint venture. OPTI's common
shares trade on the Toronto Stock Exchange under the symbol OPC.
