We have acted as Canadian counsel to SMART Technologies Inc., a company amalgamated under the Business Corporations Act (Alberta) (the “Company”), in connection with the registration pursuant to a registration statement (the “Registration Statement”) under the Securities Act of 1933, as amended, of up to 40,595,000 Class A Subordinate Voting Shares of the Company (the “Shares”), of which 8,800,000 Shares will be issued and sold by the Company and up to 31,795,000 Shares will be sold by certain selling shareholders (the “Selling Shareholders”) (including up to 5,295,000 Shares issuable upon exercise of an over-allotment option granted by the Selling Shareholders). We understand that the Shares are to be sold to the underwriters for resale to the public as described in the Registration Statement and pursuant to an underwriting agreement, substantially in the form of which is filed as an exhibit to the Registration Statement, to be entered into by and among the Company, the Selling Shareholders and the underwriters (the “Underwriting Agreement”). This opinion is being delivered in connection with the Registration Statement, to which this opinion appears as an exhibit.

We have examined the Registration Statement and, for the purposes of this opinion, we have also examined the originals, or duplicate, certified, conformed, telecopied or photostatic copies, of such corporate records, agreements, documents and other instruments and have made such other investigations as we have considered necessary or relevant for the purposes of this opinion. With respect to the accuracy of factual matters material to this opinion, we have relied upon certificates or comparable documents and representations of public officials and of officers and representatives of the Company.

In giving this opinion, we have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals, the conformity to authentic original documents of all documents submitted to us as duplicates, certified, conformed, telecopied or photostatic copies and the authenticity of the originals of such latter documents.

We are qualified to express opinions only with respect to the laws of the Province of Alberta and the federal laws of Canada applicable therein. We express no opinion on the laws of any jurisdiction other than the Province of Alberta and the federal laws of Canada applicable therein.

Based and relying upon the foregoing, and subject to the qualifications, assumptions and limitations stated herein, we are of the opinion that: (i) the Shares to be issued and sold by the Company have been duly authorized and, when such Shares are issued and paid for in accordance with the terms of the Underwriting Agreement, will be validly issued, fully paid and nonassessable, and (ii) the Shares to be sold by the Selling Shareholders have been duly authorized and are validly issued, fully paid and are nonassessable.
