EXPLANATORY NOTE

This annual report on Form 40-F is filed by Granite Real Estate Investment Trust ("Granite REIT") and Granite REIT Inc.
("Granite GP", together with Granite REIT, the "Registrants" and each a "Registrant"). The Annual Information Form, Management's Discussion and Analysis of Operations and Financial Position and
audited financial statements filed as Exhibits to this annual report relate to the combined operations and activities of the Registrants. For more information regarding the Registrants and the Stapled
Units, see "Description of the Stapled Units" below.

DESCRIPTION OF THE STAPLED UNITS

On January 3, 2013, Granite Real Estate Inc. ("Granite Co.") completed its conversion from a corporate structure
to a stapled unit Real Estate Investment Trust structure. The conversion was implemented pursuant to a plan of arrangement under theBusiness Corporations
Act(Québec) (the "2013 Arrangement"). Under the 2013 Arrangement, all of the common shares of Granite Co. were exchanged, on a one-for-one basis,
for stapled units (the "Stapled Units"), each of which consists of one unit of Granite REIT and one common share of Granite GP. The Registrants, through Granite REIT Holdings Limited
Partnership and its subsidiaries, continue to carry on the business previously conducted by Granite Co. and its subsidiaries. For more information regarding the Stapled Units and the 2013
Arrangement, see the Annual Information Form dated March 2, 2016, filed as Exhibit 1 to this annual report on Form 40-F.

CONTROLS AND PROCEDURES

A.Disclosure controls and procedures.    The Chief Financial Officer and Interim Chief Executive Officer of the
Registrants has evaluated the effectiveness of the Registrants' 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"). He has concluded that, as of the Evaluation Date, the Registrants' disclosure controls and procedures were effective to ensure that
material information relating to the Registrants would be made known to him and would be disclosed on a timely basis.

B.Report on internal control over financial reporting.    The Registrants' 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 Registrants.

The
Registrants' 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 Registrants' 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 Registrants' 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 Registrants' assets that could
have a material effect on the financial statements.

Under
the supervision and with the participation of the Registrants' Chief Financial Officer and Interim Chief Executive Officer, management conducted an evaluation of the effectiveness
of the Registrants' internal control over financial reporting, as of the Evaluation Date, based on the framework set forth in Internal Control-Integrated Framework (2013) issued by the Committee of
Sponsoring Organizations of the Treadway Commission (COSO). Based on its evaluation under this framework, management concluded that the Registrants' internal control over financial reporting was
effective as of the Evaluation Date.

Deloitte LLP,
an independent registered public accounting firm, who audited and reported on the combined financial statements for the year ended December 31, 2015, which
are filed as Exhibit 2 to this annual report, has also issued an attestation report under standards of the Public Company Accounting Oversight Board (United States) on the
Registrants' internal control over financial reporting as of the Evaluation Date. The required attestation report is appended to the audited combined financial statements for the year ended
December 31, 2015, filed as Exhibit 2 to this annual report.

C.Changes in internal control over financial reporting.    As of the Evaluation Date, there were no changes in the
Registrants' 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 Registrants' internal control over financial reporting.

---



D.Limitations on the effectiveness of controls and procedures.    The Registrants' management, including the Chief
Financial Officer and the Interim Chief Executive Officer, does not expect that the Registrants' 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

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

Each
Registrant's Board of Trustees or Board of Directors, as applicable, has determined that it has one audit committee financial expert (as such term is defined in
Form 40-F) serving on its Audit Committee. Each Registrant's Board of Trustees or Board of Directors, as applicable, 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 Registrants. 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 or the Board of Trustees, as applicable, 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 the Board of Directors or the Board of Trustees, as applicable.
