	RE:	Form 40-F for Fiscal Year Ended December 31, 2004
      Filed March 29, 2005
      File No. 0-20115

Dear Mr. Cameron:

		We have reviewed your filing and have the following

	Please understand that the purpose of our review process is

FORM 40-F FOR FISCAL YEAR ENDED DECEMBER 31, 2004

General

1. Where a comment below requests additional disclosures or other
revisions to be made, please show us in your supplemental response
what the revisions will look like.  Some of our comments refer to
US
GAAP literature.  If your accounting under Canadian GAAP differs
from
your accounting under US GAAP, please also show us the additional
disclosures that will be included in your US GAAP reconciliation
footnote.  These revisions should be included in your future
filings.



Management`s Discussion and Analysis of Financial Condition and
Results of Operations

Liquidity & Capital Resources

2. Your caption "cash flows from operating activities5" here and
in
the liquidity & capital resources section is confusingly similar
to a
GAAP measure.  However, it specifically omits changes in non-cash
working capital and the utilization of prepaid natural gas, cash
flows related to interest and other income, interest expense,
income
taxes, asset restructuring charges and other unusual items.
Please
consider modifying your caption to eliminate this confusion,
rather
than using a footnote to the title.

Summary of Contractual Obligations and Commercial Commitments

3. Please revise your table of contractual cash obligations to
include estimated interest payments on your debt, planned funding
of
pension benefit obligations and estimated payments under your
interest rate swap contract and forward exchange contracts.
Because
the table is aimed at increasing transparency of cash flow, we
believe these payments should be included in the table.  Please
also
disclose any assumptions you made to derive these amounts.

Supplemental Non-GAAP Measures

4. Your EBITDA is not computed as it is commonly defined.  Please
consider using "adjusted EBITDA" or "EBITDA excluding unusual
items"
to reflect this departure from the most common definition of
EBITDA.

Financial Statements

Note 1 - Significant Accounting Policies

(m) - Revenue Recognition

5. You indicate that revenue is generally recognized as risk and
title to the product transfers to the customer, which usually
occurs
at the time shipment is made.  Please tell us how you determine
that
title transfers at the time of shipment.  Please disclose and
explain
situations where title does not transfer at the time of shipment.
Also, please disclose whether your products are shipped FOB
shipping
point or FOB destination, if applicable.






Exhibit 4

Reconciliation with Unites States Generally Accepted Accounting
Principles

6. Please reconcile between cash and cash equivalents under
Canadian
GAAP and US GAAP.  Please then reconcile your operating, investing
and financing activities under Canadian GAAP to those that would
be
presented under US GAAP.
