EXPLANATORY NOTE



Brookfield Canada Office Properties (the “registrant”)
is filing this Amendment No. 1 to Form 40-F to revise the previously filed Annual Information Form, which was filed as Exhibit
99.1 to the registrant's Form 40-F filed March 21, 2013.  The revised Annual Information Form includes a description
of exemptive relief the registrant has been granted in relation to Canadian securities law requirements governing related party
transactions. The relief permits the registrant, subject to certain conditions, to include the Class B LP units of Brookfield Office
Properties Canada LP in the calculation of the registrant’s market capitalization for purposes of the exemption from the
minority approval and formal valuation requirements for transactions that have a fair market value of less than 25% of an issuer’s
market capitalization. Other than as set forth above, this Amendment No. 1 does not, and does not purport to, update or restate
the information in any Item of the annual report on Form 40-F or reflect any events that have occurred after the Form 40-F was
initially filed.
