The Globe and Mail reports in its Saturday edition that Canada, Mexico and the United States failed to reach a preliminary deal to alter the North American free-trade agreement at a high-level meeting Friday. The Globe's Adrian Morrow writes that professional negotiators will continue meeting to sort out details while Foreign Affairs Minister Chrystia Freeland will keep in regular contact with U.S. Trade Representative Robert Lighthizer and Mexican Economy Minister Ildefonso Guajardo. Ms. Freeland, however, would not put a date on reaching an agreement in principle. She said negotiators have entered "a new, more intensive phase of engagement." Unnamed sources say it remains unclear exactly what the scope of an agreement will be: a limited deal that covers only the crucial auto sector while punting other tough issues to future negotiations; a more expansive pact that settles several contentious issues in principle while leaving details to be worked out; or a complete agreement that makes a handful of changes while leaving other sections of NAFTA untouched. Also undecided is whether the three countries will meet the U.S.'s goal of having something to announce next week at the Summit of the Americas in Peru.
