Canada launched a formal challenge at the World Trade Organizations against the European Union for its ban on Canadian seal products, the National Post reported. Ottawa asked the WTO to form a dispute resolution panel to review whether the EU ban violates WTO rules. The ban came into effect in 2010. A report tabled this week from the House of Commons parliamentary committee on trade suggested the seal issue could hurt the chances that the Canada-European Union free trade agreement will be ratified. This is because the European Parliament now has veto powers over the trade deal since the coming into effect of the Lisbon Treaty in 2009.
