How many jobs in the USA depend on trade with Canada

President Trump's historic summit with Kim Jong-un in Singapore was overshadowed by the tumultuous climax of the G7 summit in Quebec. America's closest allies are still reeling from the divisive summit, and shortly after it ended, Trump insulted Canadian Prime Minister Justin Trudeau in a series of tweets. This was in response to a press conference held by Trudeau at which he announced retaliatory measures against US tariffs on steel and aluminium. Trump labelled Tudeau "very dishonest and weak" and claimed he "acts hurt when challenged", which infuriated Canadians. The Globe and Mail newspaper called Trump's outburst "one of the most shamelessly orchestrated crises ever perpetrated by an American government against an ally."
As there is no sign of the dust settling any time soon, it makes sense to take a quick look at whether Canada has leverage in a potential trade war. The Canadian government has often highlighted the fact that Canada is the most important trading partner for 35 US states, yet there are only two states with which trade accounts for more than 10 per cent of economic output. On the other hand, Canadian provinces have always been dependent on US trade - 49 per cent of GDP from Ontario depend on it. In Alberta it is 31 per cent and in Québec 23 per cent.
Nevertheless, the US could suffer economically in a trade war, and it is quite possible that some states could feel the first effects on their employment rates. Last year, the website canadianbusiness.com analysed government figures from both countries to determine how many US jobs per state depend on trade with Canada. The analysis found that a total of around 9 million jobs depend on cross-border trade, with California (1.66 million), New York (680,900) and Florida (620,000) being the most affected. Even if President Trump maintains his protectionist stance on trade with his key allies, the US will certainly not be immune from retaliation.
