Britain’s decision to leave the EU could jeopardize a massive free trade deal with Canada. It upsets a "fine balance" that took years to negotiate, says former Tory trade minister Ed Fast.

The European Union is giving its 28 member countries a say on the final ratification of its mammoth free trade deal with Canada in order to quell rising anti−trade sentiments.

Obama’s chiding of Canada on its commitment to NATO was one of the few discordant notes in an otherwise friendly visit to Ottawa.

Pena Nieto’s anti−isolationism message came one day after he and Prime Minister Justin Trudeau trumpeted their bilateral relationship as a model of political and economic co−operation.

Human rights questions have followed Pena Nieto to Canada this week, where he has tried to keep the focus on deepening economic and environmental co−operation with Canada and the United States.

Although both changes are still months away, Trudeau and Mexican President Enrique Pena Nieto expressed satisfaction that the two main irritants in their bilateral relationship would be removed.

Obama, Prime Minister Justin Trudeau and Mexico’s Enrique Peña Nieto will release what he called a "a comprehensive North American climate, clean energy and environment partnership."

Canada and Mexico must also take the opportunity to strengthen their bilateral co−operation as a counterweight to an incoming U.S. administration in 2017 that is likely to be more inward looking.

Trudeau will host Mexican President Enrique Peña Nieto during a state visit next week before the North American leaders’ summit that will also include U.S. President Barack Obama.

Trudeau said he wants to see Britain continue to be a strong voice in support of trade and economic prosperity as the country’s voters decide Thursday whether to remain part of the 28−country bloc.
