The Canadian Accounting Standards Board (AcSB) announced that all Publicly Accountable Enterprises will replace the use of the Generally Accepted Accounting Principles (GAAP) by the International Financial Reporting Standards (IFRS), starting January 2011. Since 2009, the enterprises are allowed to adopt the new accounting standards. The objective of the research project is to examine the adoption behaviour of a sample of Canadian private enterprises to identify the factors explaining the timing of the adoption of IFRS (2009, 2010 or 2011), and the policy choices made under the preferred framework.
