State below in reasonable detail the reasons why Forms 10-K, 20-F, 11-K, 10-Q, N-SAR, N-CSR or the transition report portion thereof, could not be filed within the prescribed time period. (Attach extra sheets if needed.)

The Annual Report on Form 11-K for the fiscal year ended December 31, 2006 (“2006 Form 11-K”) of the IMAX Corporation 401(k) Retirement Plan (the “Plan”) cannot be filed within the prescribed time period because additional time is necessary to prepare the Plan’s financial statements. Consequently, the Plan’s 2006 Form 11-K cannot be filed by its due date of June 29, 2007; however, the Plan expects to file its 2006 Form 11-K no later than July 13, 2007.
