Exhibit (a)(5)(iii)


This announcement is neither an offer to purchase nor a solicitation of an
offer to sell Securities (as defined below). The Offers (as defined below) are
made only by the Offer Documents (as defined below), and any amendments or
supplements thereto, and are being made to all holders of Securities. The
Offers are not being made to, nor will deposits be accepted from or on behalf
of, holders of Securities in any jurisdiction in which the making or acceptance
of the Offers would not be in compliance with the laws of such jurisdiction.
However, the Offeror (as defined below) or its agents may, in its or their sole
discretion, take such action as it or they may deem necessary to extend the
Offers to holders of Securities in any such jurisdiction.

                               TELUS CORPORATION

     The above-mentioned offers (the "Offers") are being made by TELUS
Corporation, a company organized under the laws of British Columbia (the
"Offeror"), to purchase all of the issued and outstanding class A restricted
voting shares (the "Class A Shares"), class B non-voting shares (the "Class B
Shares" and, collectively with the Class A Shares, together with the associated
Rights (as defined in the Offer Documents), the "Shares", including Shares
issuable upon the exercise of outstanding options, warrants or other conversion
or exchange rights other than the Rights), Warrants 2005 and Warrants 2008
(collectively, the "Warrants", and together with the Shares, the "Securities")
of Microcell Telecommunications Inc. (the "Company"), at a price of Cdn.$29.00
per Class A Share, Cdn.$29.00 per Class B Share, Cdn.$9.67 per Warrant 2005 and
Cdn.$8.89 per Warrant 2008, in each case, net to the seller in cash, without
interest, upon the terms and subject to the conditions set forth in the offers
to purchase (the "Offers to Purchase") and the related offering circular (the
"Circular"), dated May 17, 2004, and letters of acceptance and transmittal (the
"Letters of Acceptance and Transmittal") (collectively, the "Offer Documents").

     THE OFFERS WILL BE OPEN FOR ACCEPTANCE UNTIL 9 P.M., TORONTO TIME, ON JUNE
22, 2004 (THE "EXPIRY TIME"), UNLESS THE OFFERS ARE WITHDRAWN OR EXTENDED BY
THE OFFEROR.

     The Offers for the Class A Shares and Class B Shares represent a premium
of 38.1% and 36.5% over the closing price of each of the Class A Shares and the
Class B Shares, respectively, on the Toronto Stock Exchange on May 13, 2004,
the date of the public announcement of the Offeror's intention to commence the
Offers.

     The offer for Class A Shares (the "Class A Offer") is subject to certain
conditions, including, without limitation, receipt of regulatory approvals, and
there being validly deposited and not withdrawn, at the Expiry Time, (1) such
number of Class A Shares under the Class A Offer which represents at least
66 2/3% of the Class A Shares outstanding; (2) such number of Class B Shares
under the offer for Class B Shares (the "Class B Offer") which represents at
least 66 2/3% of the Class B Shares on a partially-diluted basis (as defined in
the Offer Documents); and (3) such number of Securities under the Offers which
represents at least 66 2/3% of the Securities on a fully-diluted basis (as
defined in the Offer Documents). Each of the Class B Offer and the offers for
Warrants (the "Warrant Offers") are subject to the condition that, at the
Expiry Time, Class A Shares have previously been purchased pursuant to the
Class A Offer or are then being purchased pursuant to the Class A Offer. Each
of the conditions of the Class A Offer, Class B Offer, and Warrant Offers is
set forth in Section 4 of the Offers to Purchase, "Conditions of the Offers".
Subject to applicable law, the Offeror reserves the right to withdraw any or
all of the Offers and not take up and pay for any Securities deposited under
such Offer(s) unless each of the conditions to such Offer(s) is satisfied or
waived by the Offeror prior to the Expiry Time.

     The Offeror estimates that, if it acquires all of the Securities pursuant
to the Offers, the total cash consideration required to purchase such
securities will be approximately Cdn.$1.1 billion (approximately equal to
U.S.$780 million). Such funding will come from the Offeror's available cash on
hand and drawdowns on its committed credit facilities. The Offers are not
conditioned on any financing arrangements or financing contingencies.

     If, within 120 days after the date of the Offers, the Offers have been
accepted by holders of not less than 90% of any class(es) of Shares, other than
Shares held at the date of the Offers by or on behalf of the Offeror and its
affiliates and associates (as such terms are defined in the Canada Business
Corporations Act), and the Offeror acquires such deposited Shares under the
Offers, the Offeror intends to acquire the Shares in such class(es) held by
each holder of Shares who did not accept the Class A Offer or Class B Offer, as
applicable, and any person who subsequently acquires any Shares of such
class(es) from such a holder on the same terms and at the same price for which
the Shares were acquired under such Offer, pursuant to the provisions of
section 206 of the Canada Business Corporations Act (a "Compulsory
Acquisition"). If the Offeror acquires less than 90% of the Shares of either
class under the Offers or the right of Compulsory Acquisition is not available
for any reason or if the Offeror elects not to proceed under such provisions,
the Offeror intends to acquire, directly or indirectly, at the same price per
Share as in the Offers, and no later than 120 days after the date of expiry of
an Offer, all of the Shares of such class in accordance with applicable law by
way of a Subsequent Acquisition Transaction (as defined in the Offer
Documents). If the Minimum Condition (as defined in the Offer Documents) is
satisfied, the Offeror should own sufficient Shares to effect a Subsequent
Acquisition Transaction. In order to effect a Subsequent Acquisition
Transaction, the Offeror may seek to cause a special meeting of the holders of
Shares of the relevant class(es) to be called to consider an amalgamation,
statutory arrangement, capital reorganization, consolidation or other
transaction involving the Offeror and/or an affiliate of the Offeror and the
Company and/or the holders of Shares of the relevant class(es) for the purpose
of the Company becoming, directly or indirectly, a wholly-owned subsidiary of
the Offeror or an affiliate. Each of the indentures governing the Warrants 2005
and Warrants 2008 provide that, in the event of a "Fundamental Transaction" (as
defined therein) in which the holders of the outstanding Shares are to receive
consideration solely in the form of cash, each holder will be deemed: (1) where
such cash consideration is, on a per Share basis, in an amount greater than the
exercise price of the Warrants, to exercise its Warrants and be entitled, upon
such deemed exercise, to receive the cash consideration which the holder of
Warrants would have been entitled to receive had the exercise of Warrants taken
place immediately prior to the Fundamental Transaction in question, less the
exercise price of the Warrants; or (2) where the cash consideration is, on a
per Share basis, equal to or less than the exercise price of the Warrants, to
surrender its Warrants without payment of any consideration. Following such
deemed exercise, all Warrants are cancelled and of no further value or effect.
The Offeror believes that a Compulsory Acquisition would be a "Fundamental
Transaction" for the purposes of the indentures governing the Warrants 2005 and
Warrants 2008, and in addition, it intends to structure any Subsequent
Acquisition Transaction that it undertakes with respect to the Shares so as to
also constitute a "Fundamental Transaction" for the purposes of the indentures
and thereby, in either event, trigger the deemed exercise provisions described
above.

     For purposes of the Offers, the Offeror will be deemed to have taken up
and accepted for payment Securities validly deposited under the Offers and not
withdrawn as, if and when the Offeror gives written notice or other
communication confirmed in writing to Computershare Trust Company of Canada
(the "Depositary") to that effect at its principal office in Toronto, Ontario,
Canada. Upon the terms and subject to the conditions of the Offers, the Offeror
will pay for Securities validly deposited under the Offers and not withdrawn by
providing the Depositary with sufficient funds (by bank transfer or other means
satisfactory to the Depositary) for transmittal to depositing holders of
Securities. The Depositary will act as the agent of persons who have deposited
Securities in acceptance of the Offers for the purposes of receiving payment
from the Offeror and transmitting payment to such persons, and receipt of
payment by the Depositary shall be deemed to constitute receipt thereof by
persons depositing Securities. Under no circumstances will interest accrue or
be paid by the Offeror or the Depositary to persons depositing Securities on
the purchase price of Securities purchased by the Offeror, regardless of any
delay in making such payment. Payment for Securities deposited and accepted for
payment pursuant to the Offers will be made only after the timely receipt by
the Depositary of (1) certificates for such Securities or confirmation of a
book-entry transfer of such Securities into the appropriate account pursuant to
the procedures set forth in the Offer Documents, (2) a Letter of Acceptance and
Transmittal or a facsimile thereof, properly completed and duly executed,
covering those Securities with signatures guaranteed, if required, in
accordance with the instructions set out in the Letter of Acceptance and
Transmittal, or an Agent's Message (as defined in the Offer Documents) in
connection with a book-entry transfer of Securities and (3) any other required
documents.

     If the consideration being offered for the Shares or Warrants under an
Offer is increased, the increased consideration will be paid to all depositing
holders of Shares or Warrants whose Shares or Warrants are taken up under the
Offer without regard to when such Shares or Warrants are taken up under the
Offer by the Offeror.

     Except as otherwise stated in Section 6 of the Offers to Purchase,
"Withdrawal of Deposited Securities", and subject to applicable law, all
deposits of Shares and Warrants pursuant to the Offers are irrevocable. Any
Shares and Warrants deposited in acceptance of the Offers may be withdrawn by
or on behalf of the depositing holder of Shares and Warrants:

     (a)  at any time prior to the Expiry Time;

     (b)  if the Shares or Warrants have not been paid for by the Offeror
          within three business days after having been taken up; or

     (c)  as required by the United States Securities Exchange Act of 1934, as
          amended (the "Exchange Act"), at any time after July 15, 2004,
          provided that the Shares or Warrants have not been accepted for
          payment by the Offeror prior to the receipt by the Depositary of the
          notice of withdrawal in respect of such Shares or Warrants.

     Withdrawals of Securities deposited under the Offers must be effected by
notice of withdrawal made by or on behalf of the depositing holder of Shares or
Warrants, as the case may be, by whom or on whose behalf such Shares or
Warrants were deposited, and such notice must be actually received by the
Depositary at the place of deposit of the applicable Shares or Warrants within
the time limits indicated above. Notice of withdrawal must: (1) be made by a
method, including facsimile transmission, that provides the Depositary with a
written or printed copy; (2) be signed by the person who signed the Letter of
Acceptance and Transmittal accompanying, or the Notice of Guaranteed Delivery
in respect of, the Shares or Warrants which are to be withdrawn; and (3)
specify such person's name, the number of Shares or Warrants to be withdrawn,
the name of the registered holder and the certificate number shown on each
certificate representing the Shares or Warrants to be withdrawn. If Securities
have been deposited pursuant to the procedures for book-entry transfer as set
forth in Section 3 of the Offers to Purchase, "Manner of Acceptance --
Book-entry Transfer", such notice of withdrawal must also specify the name and
number of the account at the Book-Entry Transfer Facility (as defined in the
Offer Documents) to be credited with the withdrawn Securities. The withdrawal
will take effect upon receipt by the Depositary of the properly completed
notice of withdrawal. For the purpose of obtaining physical possession of the
deposited Share or Warrant certificates so withdrawn, the signature on the
notice of withdrawal must be guaranteed by an Eligible Institution (as defined
in the Offer Documents), except in the case of Shares or Warrants deposited for
the account of an Eligible Institution.

     Withdrawals may not be rescinded and any Securities withdrawn will
thereafter be deemed not validly deposited for purposes of the Offers. However,
withdrawn Securities may be redeposited no later than the Expiry Time by again
following one of the procedures described in Section 3 of the Offers to
Purchase, "Manner of Acceptance". Once the Offeror accepts the deposited
Securities for payment upon the expiration of the Offers, holders of Securities
will no longer be able to withdraw them, except in accordance with applicable
law. If the Offeror extends the Offers, is delayed in taking up or paying for
Securities or is unable to take up or pay for Securities for any reason, then,
without prejudice to the Offeror's other rights, Securities deposited under the
Offers may be retained by the Depositary on behalf of the Offeror and such
Securities may not be withdrawn except to the extent that depositing holders of
Shares or Warrants are entitled to withdrawal rights as set forth in Section 6
of the Offers to Purchase, "Withdrawal of Deposited Securities", or pursuant to
applicable law.

     All questions as to the validity (including timely receipt) and form of
notices of withdrawal will be determined by the Offeror in its sole discretion,
and such determination will be final and binding. None of the Offeror, the
Depositary, the Dealer Managers, a Soliciting Dealer (as such terms are defined
in the Offer Documents) or any other person will be under any duty to give
notice of any defect or irregularity in any notice of withdrawal or shall incur
any liability for failure to give such notice.

     Pursuant to Rule 14d-11 under the Exchange Act and applicable Canadian
securities laws, the Offeror may elect to make available a subsequent offering
period by extending one or more of the Offers on one occasion for a period of
at least ten calendar days and not to exceed 20 business days (the "Subsequent
Offering Period") if, on the date such Offer expires, the conditions to such
Offer set forth in Section 4 of the Offers to Purchase, "Conditions of the
Offers", have either been satisfied or waived. The Offeror does not currently
intend to include a Subsequent Offering Period with respect to any of the
Offers, although it reserves the right to do so in its sole discretion. The
same form and amount of consideration will be paid to holders depositing Shares
or Warrants during the Subsequent Offering Period, if one is included, as would
have been paid prior to the commencement of such period. The Offeror will
promptly take up and pay for all Shares or Warrants validly deposited during
the Subsequent Offering Period with respect to an Offer. Notwithstanding the
provisions of United States federal securities laws relating to subsequent
offering periods, the Offeror will permit withdrawal of deposited Shares or
Warrants during any Subsequent Offering Period, if there is one, at any time
prior to such Shares or Warrants being purchased by the Offeror under an Offer.

     Subject to the limitations described in the Offer Documents, the Offeror
expressly reserves the right, in its sole judgement, at any time and from time
to time during the Offer Period (as defined in the Offer Documents) or at any
other time if permitted by applicable law, to extend the Offer Period for an
Offer or to vary any of the Offers by giving written notice, or other
communication confirmed in writing, of such extension or variation to the
Depositary at its principal office in Toronto, Ontario, Canada, and by causing
the Depositary as soon as practicable thereafter to communicate such notice to
all holders of Shares and/or Warrants that have not been taken up prior to the
extension or variation in the manner set forth in Section 11 of the Offers to
Purchase, "Notices and Delivery". The Offeror will, as soon as practicable
after giving notice of an extension or variation to the Depositary, make a
public announcement of the extension or variation, such announcement in the
case of an extension to be disseminated no later than 9 a.m., Toronto time, on
the next business day after the previously scheduled Expiry Time, and will
provide a copy of the notice to the Toronto Stock Exchange. During any such
extension or in the event of any such variation or change in information, all
Shares or Warrants deposited and not taken up or withdrawn will remain subject
to the Offers and may be taken up by the Offeror in accordance with the terms
of the Offers, subject to Section 6 of the Offers to Purchase, "Withdrawal of
Deposited Securities". Notwithstanding the foregoing, but subject to applicable
law, an Offer may not be extended by the Offeror if all of the terms and
conditions of the Offer, except those waived by the Offeror, have been
fulfilled or complied with, unless the Offeror first takes up all Shares or
Warrants validly deposited under such Offer and not withdrawn.

     All holders of Securities should consult with their tax advisors as to the
particular tax consequences of the Offers to them, including the applicability
and effect of the income and other tax laws of any country, province,
territory, state or local tax authority. For a discussion of material Canadian
federal income tax consequences and material United States federal income tax
consequences of the Offers, including with respect to a Compulsory Acquisition
or Subsequent Acquisition Transaction, see Sections 16 and 17 of the Circular,
"Material Canadian Federal Income Tax Considerations" and "Material United
States Federal Income Tax Considerations", respectively.

     A request has been made to the Company for the use of the Company's
shareholder and warrantholder lists for the purpose of disseminating the Offer
Documents to holders of Securities. Upon compliance by the Company with this
request, the Offer Documents and other relevant materials will be mailed to
holders of record of Securities and furnished to brokers, dealers, banks, trust
companies and similar persons whose names, or the names of whose nominees,
appear on the Company's shareholder and warrantholder lists or, if applicable,
who are listed as participants in a clearing agency's security position
listing, for subsequent transmittal to beneficial owners of Securities.

     The information required to be disclosed by Rule 14d-6(d)(1) of the
Exchange Act is contained in the Offer Documents and is incorporated herein by
reference in its entirety.

     THE OFFER DOCUMENTS CONTAIN IMPORTANT INFORMATION WHICH SHOULD BE READ
CAREFULLY BEFORE ANY DECISION IS MADE WITH RESPECT TO THE OFFERS.

     Questions and requests for assistance or copies of the Offer Documents and
other offer documents (which may be obtained without charge) may be directed to

taxes with respect to the purchase of Securities by the Offeror pursuant to the
Offers is payable by any holder of Securities who deposits its Securities
directly with the Depositary or who utilizes the services of a Soliciting

to any broker, dealer or other person (other than to the Dealer Managers, the
