                             INTRODUCTORY STATEMENT

     This Amendment No. 1 (this "Amendment") amends and supplements the 
Tender Offer Statement on Schedule TO-I originally filed with the Securities 
and Exchange Commission on July 5, 2005 (as amended, the "Schedule TO-I") by
Celestica Inc., an Ontario, Canada corporation ("Celestica"), relating to an
offer by Celestica to purchase the Liquid Yield Option(TM) Notes due 2020 (Zero
Coupon-Subordinated) issued by Celestica on August 1, 2000 (the "Securities"),
upon the terms and subject to the conditions set forth in the Indenture (as
defined below), Celestica's notice, dated July 5, 2005 (the "Company Notice"),
the Securities and the related offer materials filed as Exhibits (a)(1)(A) to
(d) to the Schedule TO-I (which Company Notice and related offer materials,
as amended or supplemented from time to time, collectively constitute the
"Option"). The Securities were issued pursuant to an Indenture, dated as of
August 1, 2000, between Celestica and JPMorgan Chase Bank, N.A. (as successor 
to The Chase Manhattan Bank), as Trustee ("Trustee") (the "Indenture").

     The information set forth in the Company Notice and related offer 
materials is incorporated into this Amendment by reference with respect to 
all of the applicable items in the Schedule TO-I, except that such 
information is hereby amended and supplemented to the extent expressly 
provided herein.

     The Option will expire at 5:00 p.m., Eastern Daylight Time, on August 2, 
2005. This Schedule TO-I is intended to satisfy the disclosure requirements 
of Rule 13e-4(c)(2) under the Securities Exchange Act of 1934, as amended 
(the "Exchange Act").

ITEMS 1 THROUGH 9.

Items 1-9 of the Schedule TO-I, which incorporate by reference the information
contained in the Company Notice, are hereby amended as follows:

In the Summary Term Sheet,  the  paragraph  titled "How Can I Determine the
Market Value of the  Securities?"  is hereby deleted and restated to read in its
entirety as follows:

         The Securities are listed on the NYSE under the symbol "CLS 20". On
June 30, 2005, the last reported sales price of the Securities on the NYSE,
expressed as a percentage of the principal amount at maturity, was 56-1/8% per
$1,000 principal amount. (Section 2.4)

In the Summary Term Sheet, the paragraph titled "What Are the Conditions to the
Purchase by Celestica of the Securities" is hereby deleted and restated to read
in its entirety as follows:

         The purchase by Celestica of validly surrendered Securities is not
subject to any conditions other than such purchase being lawful and that there
is not a continuing Event of Default (as defined in Section 2.1) as of the date
of repurchase (other than a default in the payment of the Purchase Price).
Conditions to the offer, other than those dependent upon receipt of necessary
government approvals, must be satisfied or waived on or before the expiration of
the Option. (Section 2.1)

In the Summary Term Sheet, the paragraph titled "If I Surrender My Securities,
When Will I Receive Payment For My Securities?" is hereby deleted and restated
to read in its entirety as follows:

         We will accept for purchase and pay the Purchase Price for all 
validly surrendered Securities promptly following the expiration of the 
Option. We will forward to the Depositary, prior to 10:00 a.m., Eastern 
Daylight Time, on August 3, 2005, the appropriate amount of cash required to 
pay the Purchase Price for the surrendered Securities, and the Depositary 
will promptly distribute the cash to the Holders. (Section 5)

The second paragraph under Section 2.1 titled "Celestica's Obligation to 
Purchase the Securities" is hereby deleted and restated to read in its 
entirety as follows:

         This Option will expire at 5:00 p.m., Eastern Daylight Time, on 
August 2, 2005 (the "Purchase Date"). Celestica will not extend the period 
Holders have to accept the Option unless required to do so by the United 
States federal securities laws. Celestica is generally required to extend the 
offering period for any material change, including the waiver of a material 
condition, so that at least five business days remain in the offering period 
after the change. The purchase by Celestica of validly surrendered Securities 
is not subject to any conditions other than that such purchase is lawful and 
that there is not a continuing "Event of Default" as of the date of 
repurchase (other than a default in the payment of the Purchase Price). An 
"Event of Default" is defined in the Indenture and means any one of the 
following events:

     (a)  default in the payment of any Securities Payment on any Security as
          and when the same shall become due and payable, including at Stated
          Maturity, in connection with any redemption or repurchase, whether or
          not such payment is prohibited by the subordination provisions of
          Article 13 of the Indenture, or failure to make a Trigger Event
          Repurchase Offer as required under the terms of the Indenture;
          PROVIDED that, after the Option Exercise Date, if such default in
          payment of a Securities Payment is a default in payment of any
          interest on any Interest Payment Date, then such default shall only
          become an Event of Default hereunder after continuance of such default
          for a period of 30 days; or

     (b)  default in the performance, or breach, of any covenant, agreement or
          warranty of the Company in the Securities or in the Indenture (other
          than a covenant, agreement or warranty a default in the performance or
          breach of which is specifically dealt with elsewhere in Section 5.01
          of the Indenture), and continuance of such default or breach for a
          period of 60 days after there has been given, by registered or
          certified mail, to the Company by the Trustee or to the Company and
          the Trustee by the Holders of at least 25% in aggregate principal
          amount at Maturity of the Outstanding Securities a written notice
          specifying such default or breach and requiring it to be remedied and
          stating that such notice is a "Notice of Default" hereunder; or

     (c)  (i) default in the payment by the end of any applicable grace period
          after maturity of indebtedness (other than nonrecourse obligations)
          for borrowed money or evidenced by bonds, debentures, notes or similar
          instruments in a principal amount in excess of $100,000,000 and
          continuance of such failure, or (ii) the acceleration of indebtedness
          (other than nonrecourse obligations) for borrowed money or evidenced
          by bonds, debentures, notes or similar instruments in a principal
          amount in excess of $100,000,000 because of a default with respect to
          such indebtedness, without such indebtedness having been discharged or
          such acceleration having been cured, waived, rescinded or annulled, in
          the case of clause (i) or (ii) above, for a period of 30 days after
          written notice to the Company by the Trustee or to the Company and the
          Trustee by the Holders of not less than 25% in aggregate principal
          amount at Maturity of the Outstanding Securities; PROVIDED, that if
          any such failure or acceleration referred to in clause (i) or (ii)
          above shall cease or be cured, waived, rescinded or annulled, then the
          Event of Default by reason thereof shall be deemed not to have
          occurred; or

     (d)  the entry by a court having jurisdiction in the premises of (i) a
          decree or order for relief in respect of the Company or any
          Significant Subsidiary in an involuntary case or proceeding under any
          applicable bankruptcy, moratorium of payments, insolvency,
          reorganization or other similar law or (ii) a decree or order
          adjudging the Company or any Significant Subsidiary bankrupt or
          insolvent, or approving as properly filed a petition seeking
          reorganization, arrangement, adjustment or composition of or in
          respect of the Company or any Significant Subsidiary under any
          applicable federal or state law, or appointing a custodian, receiver,
          liquidator, assignee, trustee, sequestrator or other similar official
          of the Company or any Significant Subsidiary or of substantially all
          of the Company's or such Significant Subsidiary's property, as the
          case may be, or ordering the winding up or liquidation of the Company
          or Significant Subsidiary's affairs and the continuance of any such
          decree or order unstayed and in effect for a period of 60 consecutive
          days; or

     (e)  the commencement by the Company or any Significant Subsidiary of a
          voluntary case or proceeding under any applicable bankruptcy,
          moratorium of payments, insolvency, reorganization or other similar
          law or of any other case or proceeding to be adjudicated a bankrupt or
          insolvent or to be granted moratorium of payment, or the consent by
          the Company or any Significant Subsidiary to the entry of a decree or
          order for relief in respect of the Company or such Significant
          Subsidiary, as the case may be, in an involuntary case or proceeding
          under any applicable bankruptcy, moratorium of payment, insolvency,
          reorganization or other similar law or to the commencement of any
          bankruptcy, moratorium of payment or insolvency proceedings against
          the Company or any Significant Subsidiary, or the filing by the
          Company or any Significant Subsidiary of a petition or consent seeking
          reorganization or similar relief under any applicable law, or the
          consent by the Company or any Significant Subsidiary to the filing of
          such petition or to the appointment of or taking possession by a
          custodian, receiver, liquidator, assignee, trustee, sequestrator or
          other similar official of the Company or Significant Subsidiary, as
          the case may be, of all or substantially all of the property of the
          Company or such Significant Subsidiary, as the case may be, or the
          making by the Company or any Significant Subsidiary of an assignment
          for the benefit of creditors, or the admission by the Company or any
          Significant Subsidiary in writing of its inability to pay its debts
          generally as they become due, or the taking of corporate action by the
          Company or any Significant Subsidiary in furtherance of any such
          action; PROVIDED, that a liquidation or winding up of a Significant
          Subsidiary pursuant to applicable corporate law shall not be deemed to
          be an Event of Default hereunder.

Capitalized terms used in the definition of "Event of Default" are defined in 
the Indenture. 

Section 2.5 titled "Redemption" is hereby deleted and restated to read in its 
entirety as follows:

         Pursuant to the terms of the Securities and the Indenture, unless
earlier redeemed, we are obligated to purchase all Securities validly
surrendered for purchase and not withdrawn, at the Holder's option, on August 2,
2005, August 1, 2010 and August 1, 2015. The purchase price per $1,000 principal
amount at maturity will be $572.82 on August 2, 2005, $689.68 on August 1, 2010
and $830.47 on August 1, 2015. In compliance with these terms, we have submitted
the Option to Holders to enable Holders to exercise this right as of August 
2, 2005.

         With respect to any Securities that are not surrendered for purchase 
pursuant to the Option, Holders and Celestica will continue to have the 
repurchase and redemption rights set forth in the Indenture. Pursuant to the 
Indenture, we are required to offer to repurchase the Securities upon a 
Delisting Event or a Change of Control (as defined in the Indenture) on or 
prior to August 1, 2005. We may pay the repurchase price upon a Change in 
Control in cash or subordinate voting shares or any combination thereof 
except in certain events. We will pay the repurchase price in cash if there 
is a Delisting Event.

         The repurchase price, upon a Delisting Event or a Change of Control, 
is equal to the Issue Price (as defined in the Indenture) plus accrued 
Original Issue Discount (as defined in the Indenture) to the date of 
repurchase plus the Make-Whole Amount (as defined in the Indenture). The 
purchase price, in these events, at August 1, 2005 would be $688.07 per 
$1,000 principal amount at maturity.

         On or after August 1, 2005, the Securities are redeemable in cash at
any time at the option of Celestica, in whole or in part, at a redemption price
equal to the Issue Price (as defined in the Indenture) plus accrued Original
Issue Discount (as defined in the Indenture and as provided for in the
Securities) to the date of redemption. The purchase prices per $1,000 principal
amount at maturity would be as follows:



                                                (1)                       (2)                    (1) + (2)
