Close relations with Europe, especially but not only with the United Kingdom, have long been a consensual tenet of Canadian foreign policy, which has supported European integration since the 1970s. The UK's withdrawal from the European Union threatens to upset this consensus. While Liberal Prime Minister Justin Trudeau has consistently cast Brexit in a negative light, Conservative leaders Andrew Scheer and Erin O'Toole have commented positively on the UK's leaving the EU. Did their polarized views resonate in the population? To answer this question, this article analyzes the results of an original survey of voting-age Canadians. Findings show a strong degree of correspondence between positions expressed in party discourse and preferences in the Canadian population. This raises the possibility that the difference between two models of transatlantic relations, which we call Eurosphere and Anglosphere, could emerge as a new fault line in Canadian foreign policy.
