The Globe and Mail reports in its Wednesday edition that the United States-Mexico-Canada Agreement is not a done deal, it still requires Congressional approval. The Globe guest columnist Colin Robertson writes that Canadian auto manufacturers have cause for celebration. It appears Canada evaded President Donald Trump's threatened 25-per-cent tariff and, even if trade is slightly more managed, the new rules of origin and the wage component could well create more opportunities, especially for Canada's highly competitive parts manufacturers -- our real niche in the global auto trade. While majority governments in Canada and Mexico will be able to secure legislative implementation, passage in the next U.S. Congress is no sure thing. We need to continue the advocacy campaign into the regions and within the Washington beltway. Mr. Robertson says to protect our interests, Ottawa and the provinces must develop a permanent outreach campaign with Washington and state governors or lieutenant governors. Premiers can help through establishing offices in the states that matter most to them. Mr. Trump used Canada's dependence on the U.S. market as leverage, highlighting Canada's need for more trade diversification.
