No matter who won the 2016 U.S. presidential election, Canada was bracing for NAFTA to go down in flames. It pointed to Clinton's repeated statements that the trade deal needed to be renegotiated, but particularly highlighted then-candidate Trump's "far stronger and far more frequent" negativity on NAFTA. Then in August 2017, Trump decided it was time to take a new look at trade in North America. If the NAFTA deal was ripped up, the rules under the CUSFTA (Canada-United States Free Trade Agreement), the previous trade agreement signed in 1987, would have been reinstated. The CUSMA trade deal isn't yet ratified, facing roadblocks in the Democrat-led U.S. Congress that threaten to delay the approval process.
