The Parliamentary Secretary on behalf of the Minister of Foreign Affairs, Matt DeCourcey, had presented the OECD Multilateral Convention to Implement Tax Treaty Related Measures to Prevent Base Erosion and Profit Shifting (MLI) on January 31, 2018, in the House of Commons. In this way, the MLI ratification process had been started. This ratification procedure is expected to be finished around March 22, 2018. Note that, an implementation bill must be announced. It needs to be approved by the parliament and receive Royal Assent. Also, Governor in Council needs to authorize it to ratify the MLI. And at the end, a ratification notice must be deposited with the OECD.  The MLI will come into effect for a particular Covered Tax Agreement after the domestic ratification procedures are completed in both Canada and the jurisdiction of the relevant treaty counterparty.
