State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q,10-D, N-SAR, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.

The independent public accountants (the "Auditors") engaged to audit the financial statements required to be filed with the Annual Report on Form 10-K (the "Annual Report") of SunOpta Inc. (the "Company") were unable to release to the Company their audit opinion in sufficient time to allow the Company to meet its filing deadline on the due date for the Annual Report. As a result, the Company could not complete the filing before the applicable filing deadline, and the delay could not be eliminated by the Company without unreasonable effort or expense. The Company filed the Annual Report for the year ended December 30, 2017 shortly after the Edgar filing deadline on the required due date, which was within the 15-day extension period provided under Rule 12b-25 of the Securities Exchange Act of 1934, as amended. The statement of the Auditors required by Rule 12b-25(c) is attached as Exhibit 99.1 to this notification of late filing.
