Canada and Mexico approach an historic juncture in their relations with the United States. Both countries face a July 1 deadline over the Canada–United States–Mexico Agreement (CUSMA) which replaced the North American Free Trade Agreement (NAFTA) in 2020 under the auspices of Justin Trudeau, Donald Trump and Andrés Manuel López Obrador. CUSMA is due to be formally extended for 16 years or to be continued under annual reviews. The Trump administration has already run roughshod over some aspects of the agreement and the unpredictable Donald Trump sometimes even seems prepared to walk away.
It’s not the first time both Canada and Mexico have simultaneously confronted a moment of such significance with a wallop from the United States.
On June 19, 1867, the French appointed Emperor of Mexico, Maximiliano de Habsburgo, was executed in Querétaro some 220 kilometres north of Mexico City. On July 1, 1867, many citizens of the Dominion of Canada celebrated the creation of a new nation state.
Consequently, each country can date the dawning of its independence within two weeks in the early summer of 1867. This independence is unofficially recognized in Mexico because while 1821 saw the overthrow of Spanish imperial rule, the official date of Mexican independence is September 16 with celebrations starting in the evening of the 15th to commemorate the beginnings of revolt against Spanish rule in 1810. The year 1821 marked the beginning of a highly conflicted independence that featured almost half a century of war between Mexican conservatives and liberals. Also in that period, war with the United States led to the loss of just over half of Mexico’s territory by 1848. Then in 1862, the French under Napoleon III invaded Mexico at the urging of some of Mexican conservatives.
Both the French invasion of Mexico and Canadian confederation were motivated to a significant extent by events in the United States – specifically the bloody American Civil War 1861 – 1865. Napoleon III miscalculated that the south would win, become his ally, and renounce the Monroe Doctrine. After the North prevailed on April 9, 1865, Napoleon III withdrew his troops and abandoned Maximiliano and the Mexican conservatives who supported him. Meanwhile in what would become Canada, British North American politicians like Macdonald, Brown and Cartier worried about an expansionary United States after the war, and having seen the internecine chaos to the south, wanted a form of union that would preserve the British political connection rather than emulating American style republican government. In sum, the American Civil War served as political accelerant on both sides of the United States border.
