It has been a wild two years for business in North America, and few other events can capture the emotions and uncertainty better than the talks to renegotiate NAFTA.

There was a time, after all, when companies believed President Donald Trump would pull out of the deal altogether. At another time, negotiators were all but certain a deal could be reached by the end of 2017. Today, with the United States-Mexico-Canada Agreement having been reached, those times feel like far-off realities.

The truth is, the past twenty-or-so months have been dramatic. Elections, trade wars, and political rhetoric often got in the way of a deal. Meanwhile, negotiators worked long nights and longer months to find common ground.

Relive the drama of the talks to renegotiate the North American Free Trade Agreement (NAFTA) with the timeline below.
