(the "COMMON SHARES") of Emco Limited ("EMCO") deposited pursuant to the Offer,
dated February 28, 2003 (the "OFFER DOCUMENT"), made by 2022841 Ontario Inc.
(the "OFFEROR"), a wholly-owned subsidiary of Blackfriars Corp., to purchase all
of the outstanding Common Shares at a purchase price of CDN $16.60 per Common
Share, net to the seller in cash, without interest thereon, upon the terms and
subject to the conditions set forth herein and in the Offer to Purchase (as

herein as the "OFFER TO PURCHASE", and the Offer to Purchase, together with this
Letter of Transmittal, as each may be amended or supplemented, together

of Transmittal and which are defined in the Offer to Purchase shall have the
same meanings herein as given to them in the Offer to Purchase. The terms and

other required documents to the Depositary prior to the Expiry Time (as defined
in the Offer Document), must tender their Common Shares according to the

               privileges as the owner of any such dividend, distribution,
               payment, right or other interest and may withhold the entire

           CERTIFICATES AND ALL OTHER REQUIRED DOCUMENTS, INCLUDING DELIVERY
           THROUGH THE BOOK-ENTRY TRANSFER FACILITY, IS AT THE OPTION AND RISK
           OF THE TENDERING SHAREHOLDER AND THE DELIVERY WILL BE DEEMED MADE
           ONLY WHEN ACTUALLY RECEIVED BY THE DEPOSITARY (INCLUDING, IN THE CASE
           OF BOOK-ENTRY TRANSFER, BY BOOK-ENTRY CONFIRMATION). IF DELIVERY IS
           BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY
           INSURED, IS RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE
           ALLOWED TO ENSURE TIMELY DELIVERY.
     (d)   No alternative, conditional or contingent deposits will be accepted.
           All depositing Shareholders waive any right to receive any notice of
           acceptance of Deposited Shares for payment by execution of this
           Letter of Transmittal (or a facsimile thereof).
     (e)   The Offer and any agreement resulting from the acceptance of the
           Offer will be construed in accordance with and governed by the laws
           of the Province of Ontario and the laws of Canada applicable therein
           and the holder of the Common Shares covered by this Letter of
           Transmittal hereby unconditionally and irrevocably attorns to the
           non-exclusive jurisdiction of the courts of the Province of Ontario
           and the courts of appeal therefrom.
     (f)   Additional copies of the Offer Document, the Circular, the Letter of
           Transmittal and the Notice of Guaranteed Delivery may be obtained on
           request and without charge from the Depositary at any of its offices
           at the addresses listed on the front page of this document.

10. LOST CERTIFICATES
     If a Share Certificate has been lost or destroyed, this Letter of
Transmittal should be completed as fully as possible and forwarded, together
with a letter describing the loss, to the Depositary. The Depositary will
respond with the replacement requirements which must be properly completed and
submitted in good order to the Depositary on or prior to the Expiry Time.

11. SUBSTITUTE FORM W-9
     Each United States Shareholder is required to provide the Depositary with a
correct Taxpayer Identification Number ("TIN") on the Substitute Form W-9, which
is provided in Block E, and to certify whether such Shareholder is subject to
backup withholding of United States federal income tax. If a United States
Shareholder has been notified by the Internal Revenue Service that such
Shareholder is subject to backup withholding, such Shareholder must cross out
item 2 of the Substitute Form W-9, unless such Shareholder has since been
notified by the Internal Revenue Service that such Shareholder is no longer
subject to backup withholding. Failure to provide the information and
certifications on the Substitute Form W-9 may subject a United States
Shareholder to a US$50.00 penalty imposed by the Internal Revenue Service and
30% United States federal income tax withholding on the payment of the purchase
price of all Common Shares purchased from such Shareholder. If a United States
Shareholder has not been issued a TIN and has applied for one or intends to
apply for one in the near future, such Shareholder should check the box in Part
1 of the Substitute Form W-9 and complete the attached Certificate of Awaiting
Taxpayer Identification Number. In such case, the Depositary will withhold 30%
of all payments of the purchase price to such Shareholder made prior to the time
a properly certified TIN is provided to the Depositary and, if the Depositary is
not provided with a TIN within 60 days, such amounts will be paid over to the
Internal Revenue Service. A United States Shareholder is required to give the
Depositary the TIN (e.g., social security number or employer identification
number) of the record owner of the Common Shares. If the Common Shares are in
more than one name or are not in the name of the actual owner, consult the
enclosed "Guidelines for Certification of Taxpayer Identification Number on
Substitute Form W-9" for additional guidance on which number to report.
     IN ORDER FOR A NON-UNITED STATES SHAREHOLDER TO PREVENT BACKUP WITHHOLDING,
SUCH PERSON MUST COMPLETE THE FORM W-8BEN ("CERTIFICATE OF FOREIGN STATUS") SET
FORTH ABOVE IN BLOCK F, TO BE SIGNED UNDER PENALTIES OF PERJURY, ATTESTING TO
SUCH PERSON'S EXEMPT STATUS.
