Management’s Responsibility for Financial Reporting February 20, 2013 PricewaterhouseCoopers LLP, an independent registered public accounting firm, appointed by the shareholders, have  audited our financial statements in accordance with Canadian generally accepted auditing standards and have expressed  their opinion in the auditor’s report. The Board of Directors oversees management’s responsibility for financial reporting and internal control systems  through an Audit Committee, which is composed entirely of independent directors. The Audit Committee meets  periodically with management, our internal auditors and independent auditors to review the scope and results of the  annual audit, and to review the financial statements and related financial reporting and internal control matters before  the financial statements are approved by the Board of Directors and submitted to the shareholders. Management has a process in place to evaluate internal control over financial reporting based on the criteria  established by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in Internal Control  – Integrated Framework. Management is responsible for establishing and maintaining adequate internal control over financial reporting. Any  system of internal control over financial reporting, no matter how well designed, has inherent limitations. Therefore,  even those systems determined to be effective can provide only reasonable assurance with respect to financial  statement preparation and presentation. The system of controls is also supported by a professional staff of internal  auditors who conduct periodic audits of many aspects of our operations and report their findings to management  and the Audit Committee. Management is responsible for the integrity and fair presentation of the financial information contained in this annual  report. Where appropriate, the financial information, including financial statements, reflects amounts based on the  best estimates and judgments of management. The financial statements have been prepared in accordance with  International Financial Reporting Standards as issued by the International Accounting Standards Board. Financial  information presented elsewhere in the annual report is consistent with that disclosed in the financial statements. Donald R. Lindsay  President and Chief Executive Officer Ronald A.
