CONTROLS AND PROCEDURES

A. Disclosure controls and procedures . The Chief Executive Officer and the Chief Financial Officer of MI Developments Inc. (the "Company") have evaluated the effectiveness of the Company's disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) as of the end of the period covered by this annual report (the "Evaluation Date"). They have concluded that, as of the Evaluation Date, the Company's disclosure controls and procedures were effective to ensure that material information relating to the Company and its consolidated subsidiaries would be made known to them by others within those entities and would be disclosed on a timely basis.

B. Report on internal control over financial reporting . The Company's management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act, for the Company.

The Company's internal control over financial reporting includes those policies and procedures that: (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the Company's assets; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that the Company's receipts and expenditures are being made only in accordance with authorizations of its management and directors; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company's assets that could have a material effect on the financial statements.

Under the supervision and with the participation of the Company's Chief Executive Officer and Chief Financial Officer, management conducted an evaluation of the effectiveness of the Company's internal control over financial reporting, as of the Evaluation Date, based on the framework set forth in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on its evaluation under this framework, management concluded that the Company's internal control over financial reporting was effective as of the Evaluation Date.

Ernst & Young LLP, an independent licensed registered public accounting firm, who audited and reported on the Company's consolidated financial statements for the year ended December 31, 2011 included in this annual report, has also issued an attestation report under standards of the Public Company Accounting Oversight Board (United States) on the Company's internal control over financial reporting as of the Evaluation Date. The required attestation report is included in the Company's Consolidated financial statements for the year ended December 31, 2011, which are filed as Exhibit 2 to this annual report on Form 40-F.

C. Changes in internal control over financial reporting . As of the Evaluation Date, there were no changes in the Company's internal control over financial reporting that occurred during the period covered by this annual report that have materially affected, or that are reasonably likely to materially affect, the Company's internal control over financial reporting

D. Limitations on the effectiveness of controls and procedures. The Company's management, including the Chief Executive Officer and the Chief Financial Officer, does not expect that the Company's controls and procedures will prevent all potential error and fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met.

AUDIT COMMITTEE AND AUDIT COMMITTEE FINANCIAL EXPERT

The Company has a separately designated standing audit committee (the "Audit Committee") established in accordance with section 3(a)(58)(A) of the Exchange Act. The members of the Audit Committee are Messrs. Gerald J. Miller, Barry Gilbertson and Scott I. Oran.

The Company's Board of Directors has determined that it has one audit committee financial expert (as such term is defined in Form 40-F) serving on its Audit Committee. The Board of Directors has determined that Mr. Miller is an audit committee financial expert and is independent, as that term is defined by the New York Stock Exchange's corporate governance standards applicable to the Company. The SEC has indicated that the designation of a person as an audit committee financial expert does not impose on such person any duties, obligations or liability that are greater than those imposed on such person as a member of the Audit Committee and the Board of Directors in the absence of such designation or identification and does not affect the duties, obligations or liability of any other member of the Audit Committee or Board of Directors.

AUDIT COMMITTEE PRE-APPROVAL POLICIES AND PROCEDURES

Please refer to the section entitled "Audit Committee" in the Company's Annual Information Form, included as an exhibit to this annual report, for details on the Company's policy relating to the pre-approval of all audit services and permitted non-audit services provided to the Company by Ernst & Young LLP. For the year ended December 31, 2011, none of the Company's audit-related fees made use of the de minimis exception to the pre-approval provisions contained in paragraph (c)(7)(i) of Rule 2-01 of Regulation S-X.

CODE OF ETHICS

The Company has adopted a "code of ethics" (as that term is defined in Form 40-F), entitled the "Code of Conduct and Ethics", that applies to all of the Company's employees, including officers, as well as directors. A copy of the Code of Conduct and Ethics has been posted to the Company's website (www.midevelopments.com). The information on the Company's website shall not be deemed to be incorporated by reference in this annual report.

ADDITIONAL DISCLOSURE

On December 7, 2011, the Board of Directors of the Company amended its Code of Conduct and Ethics to, among other things, expressly prohibit the making of bribes, kickbacks, favors, or any other thing of value, directly or indirectly, to any government official, consistent with the Company's anti-bribery policy. Under the Code of Conduct and Ethics, as amended, there is no exception for small, facilitating payments (so-called "grease" payments). The description above is qualified in its entirety by reference to the amended Code of Conduct and Ethics, which is attached hereto as Exhibit 4 and incorporated herein by reference.
