time and, as a result, the existence of a "group" under Rule 13d-5 of the
Exchange Act shall terminate at such time.

ITEM 1.  SECURITY AND ISSUER.

         This statement relates to the common stock, par value $.01 per share
(the "Common Stock"), of International Alliance Services, Inc., a Delaware
corporation formerly known as Republic Environmental Systems, Inc. (the
"Issuer"). The principal executive offices of Issuer are located at 10055 Sweet
Valley Drive, Valley View, Ohio 44125.

ITEM 2.  IDENTITY AND BACKGROUND.

         (a) - (c), (f) This Statement is being filed by MGD Holdings Ltd., a
Bermuda corporation ("MGD"), and Mr. Michael G. DeGroote (all of the foregoing
collectively, the "Reporting Persons" and individually, the "Reporting Person").
A copy of an agreement among the Reporting Persons with respect to their joint
filing of this Statement is attached hereto as Exhibit 1.

         MGD is a Bermuda corporation engaged principally in investing in the 
securities of Issuer.  Mr. DeGroote is a controlling stockholder of MGD.  Mr. 
DeGroote, Chairman of the Board of Issuer, is a Canadian citizen but resides 
in Bermuda.  The principal business address of each of the Reporting Persons 
is Victoria Hall, 11 Victoria Street, P.O. Box HM 1065, Hamilton, HMEX Bermuda.

         The name, business address, principal occupation or employment and
citizenship of each executive officer and director of MGD are listed on Schedule
A, attached hereto and incorporated herein by reference.

         (d) - (e) During the last five years, none of the Reporting Persons
nor, to the best of any of their knowledge, any of the persons listed on
Schedule A attached hereto, has been (i) convicted in a criminal proceeding
(excluding traffic violations and similar

                                        4

misdemeanors) or (ii) a party to a civil proceeding of a judicial or
administrative body of competent jurisdiction and as a result of such proceeding
was or is subject to a judgment, decree or final order enjoining future
violations of, or prohibiting or mandating activities subject to, Federal or
state securities laws or finding any violation with respect to such laws.

ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

         MGD acquired (i) 2,380,000 shares of Common Stock on April 26, 1995 as
part of a distribution of the Common Stock of Issuer to stockholders of record
of Republic Industries, Inc., ("RII") (as described in Item 4, below) and (ii)
200,000 shares of Common Stock through purchases on the open market. MGD
effected the acquisition of the shares of Common Stock described in (ii) with
cash on hand and capital contributions.

         Additionally, on October 18, 1996, MGD acquired (i) 1,900,000 shares of
Common Stock and (ii) warrants to purchase an aggregate of 5,700,000 shares of
Common Stock. The source of the $4,987,500 to be used by MGD for such purchase

contributions.

are executive officers and directors of MGD as listed on Schedule A, for their

April 21, 1995 of one (1) share of Common Stock for every five (5) shares of
common stock of RII ("RII Common Stock") owned on that date (the
"Distribution"). At the time of the Distribution by RII, RII was the sole
stockholder of the Common Stock. Approximately 5.4 million shares of Common
Stock were distributed to RII stockholders. In addition, in connection with the
Distribution, MGD was issued Warrants dated as of April 26, 1995, to acquire .2
shares of Common Stock for each share of RII Common Stock purchased by MGD under
