The federal government has announced it will begin the process of restricting the importation of milk protein concentrates.Dairy Farmers of Canada chairperson Jaques Laforges notes Canadian processors have been displacing domestic production with the cheaper off-shore alternatives.  The process involves invoking a clause in the general agreement on tarriffs and trade which allows a country to renegotiate its tariff concessions at the World Trade Organization.  Laforge says this will level the playing field between processors who had been using imported milk protein, and those who had stuck with domestically produced product.  He expects the negotiating process will take 4 to 6 months to complete.  The overall outcome of the process will be new tariffs and the establishment of new tariff rate quotas.  In exchange for that Canada must provide other WTO members with equivalent compensation.
