The Montreal summit’s most persistent critics were not in the room, and their objections will follow the agreement home. Conservative Leader Pierre Poilievre objected to aligning with European policies and to the EU carbon border tariff, arguing that Canada should not import European rules as the price of closer cooperation. The Bloc Quebecois, meanwhile, says Prime Minister Mark Carney must hold a promised vote and negotiate with Quebec where provincial jurisdiction is touched. Together, those objections frame the opposition case against the Alliance for the Future.
Poilievre’s argument is about sovereignty in the opposite direction from Carney’s. Carney told reporters that above all, this is about sovereignty, meaning sovereignty gained by diversifying away from the United States. Poilievre argues that sovereignty is lost when Canada aligns its policies with Europe, particularly on carbon, where the EU’s carbon border adjustment mechanism imposes a charge on imports based on their emissions. For Canadian exporters, that charge could become a cost of selling into Europe, and for Canadian voters, it could become a symbol of rules made elsewhere.
The objected to aligning with European policies position also raises a practical question: how much alignment does the alliance actually require? The summit text speaks of ever closer association, a phrase that replaced the stronger associate membership language promoted in September, after Germany led the push to drop it. Ever closer association is deliberately vague, which allows supporters to describe it as cooperation and critics to describe it as a first step toward obligations that have not yet been spelled out.
Quebec’s separate objection
Quebec’s objection is different in kind. The Parti Quebecois premier, Paul St-Pierre Plamondon, boycotted the Montreal meeting after being refused a public speaking role, and the Bloc Quebecois says Carney must hold a promised vote and negotiate with Quebec where the agreement touches provincial jurisdiction, including areas such as education, culture and natural resources. That is not an argument about carbon tariffs, but about federalism: whether Ottawa can commit Canada to closer association with Europe in areas where provinces have a constitutional role, without their consent.
Carney’s government has argued that the alliance is a federal responsibility, covering defence, trade and foreign policy, and that provincial concerns will be addressed through consultation. Quebec’s parties are not satisfied with consultation, and they have a lever: a vote in the House, if Carney honours his promise, and public pressure in Quebec, where the summit was held and where the boycott was visible. The test of that lever will come when the first agreement under the alliance touches a provincial area, and Quebec asks whether it was consulted, or merely informed.
What the opposition case means for 2027
Both objections will shape the 2027 summit, by which time ever closer association is supposed to be defined. Poilievre will ask whether alignment has cost Canadian exporters, and whether carbon charges have raised prices. Quebec will ask whether its jurisdiction was respected, and whether its vote was held. Carney will need answers to both, because an alliance that is popular in Montreal but contested in Ottawa and Quebec City is an alliance whose definition will be fought over, not agreed.
The Montreal summit launched a partnership. The opposition case ensures that partnership will be debated, and that debate, in Parliament and in Quebec, is where the alliance will either gain democratic legitimacy, or become another summit agreement that voters feel was decided above their heads.
