CETA entered into force provisionally on September 21, 2017, meaning that most of the agreement is now in force. This is one of the great advantages of CETA for EU businesses. Canada has opened its public tenders to EU companies more than with any of its other trading partners. Irish and European businesses will be able to not be at the federal level, but also for Canadian provinces and municipalities, the first non-Canadian companies to be able to offer goods and services. The Canadian public procurement market in the provinces is estimated to be double its federal equivalent. Negotiations ended in August 2014. All 28 EU member states have approved the final text of CETA, with Belgium being the last country to give its approval.  Justin Trudeau, Prime Minister of Canada, travelled to Brussels on October 30, 2016 to sign on behalf of Canada.  The European Parliament approved the agreement on 15 February 2017.  The agreement is subject to ratification by the EU and national lawmakers.
  It could only come into force if, at Belgium`s request, the European Court of Justice had not issued a negative opinion on the dispute settlement mechanism.  In its opinion, the European Court of Justice found that the dispute settlement mechanism was in line with EU law.  Until it enters into formal force, the essential parts apply on an interim basis from 21 September 2017.  CETA is Canada`s largest bilateral initiative since nafta. It was launched as a result of a joint study „Assessing the Costs and Benefits of a Closer EU-Canada Economic Partnership“ published in October 2008. Officials announced the opening of negotiations on May 6, 2009 at the Canada-EU Summit in Prague   At the conclusion of the Canada-EU Summit in Ottawa on March 18, 2004, at which the Heads of State and Government agreed on a framework for a new Canada-EU Trade and Investment Promotion Agreement (TIEA). TIEA should go beyond traditional market access issues and include areas such as trade and investment facilitation, competition, mutual recognition of professional qualifications, financial services, e-commerce, temporary access, small and medium-sized enterprises, sustainable development and the exchange of knowledge and technology. TIEA should also build on a regulatory cooperation framework between Canada and the EU to promote bilateral cooperation on the regulatory approach, promote best regulatory practices and facilitate trade and investment. In addition to removing barriers, TIEA is expected to increase Canadian and European interest in each other`s markets.
 TIEA lasted until 2006, when Canada and the EU decided to halt negotiations. This has led to negotiations for a canada-EU trade agreement (later renamed the Comprehensive Economic and Trade Agreement (CETA) and this agreement, beyond TIEA, is in line with an agreement with a much broader and more ambitious scope. In cetA`s consolidated text, iPR (p. 339-375) deals with copyright, trademarks, patents, drawings, trade secrets and licenses. It refers to the TRIPS agreement (p. 339 f). In addition to the interests of the pharmaceutical industry and software, CETA encourages the continuation of the camera (Article 5.6, p. 343). Negotiations on food exports, in particular, have been very long. Interests in European cheese exports and Canadian beef exports have led to the protection of this type of intellectual property and long lists of „geographic indications for the identification of a product originating in the European Union“ (p. 363-347).  Canada and the EU have a long history of economic cooperation.
