at least one for each trade treaty being compared, then picking on particular issues and comparing the treaties, Canada is a part of three major international trade treaties: The Canada-Mexico-United States Agreement that replaced the North American Free Trade Agreement (NAFTA). (This agreement has different names in the different countries. Americans call it USMCA. Some Canadians call it NAFTA II; others call it CUSMA.) The Canada-European Union Comprehensive Economic & Trade Agreement (CETA). The Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP). (Canada has also negotiated many other one-on-one agreements with individual countries, but we are not talking about them.) Canada is the only country in the world with continental scale, multi-country agreements spanning the globe, potentially allowing Canadian companies to act as an international hub if the companies can navigate the different terms in these agreements. Your comparison should cover the following items: What are the limits wrapped around any opening of the market for trade? How does this apply to goods? To services? To labour mobility (ability for people to move freely)? In the event of disputes, what legal procedures are called for? Does the agreement protect intellectual property and other property rights? Who benefits the most? (Multi-national corporations, large domestic companies, small companies, entrepreneurs)? I'm satisfied if you use summaries and analyses you research to understand these agreements rather than read the original source text: as a consultant, I had to digest the original NAFTA agreement : it took me five weeks to understand it. So find good summaries (accounting firms, major management consulting firms, and government information for international trade are good places to search) and go from there.
