OTTAWA — The 3.5-million French-speaking Walloons of Belgium are standing in the way of the seven years of negotiations that led to the wide-ranging free trade deal between the 35 million people of Canada and the 500 million living in the European Union. The Wallonia region has an effective veto over the deal because Belgium's constitution gives them that power over the country's national government. Here are five things at the heart of Wallonia's discontent over the deal, known as CETA:

Too much corporate power While the Walloons are worried their agriculture sector will suffer under the deal, they are increasingly concerned about the investor-state dispute settlement system as well. The region's socialist government has adopted many of the concerns of the civil society groups that oppose the free trade deal: they say it gives multinational corporations too much power to sue governments if they make regulations that affect their ability to turn a profit. 2. Trade tribunals The Walloons want changes to the ISDS provisions of the treaty, specifically the tribunals that would settle disputes. They want them to be more transparent to eliminate the possibility of bias or conflict of interests by the people appointed to adjudicate disputes.
