Nationalism is deeply-rooted on the Canadian left, and it’s not hard to imagine scenarios where the nationalist challenge comes from there. Some elements in the nationalist left — Maude Barlow, for one — find themselves both agreeing with the nationalism of Donald Trump and trying to avoid being associated with him. This stance may be harder to sustain if the flow of immigrants — and especially unskilled immigrants — increased sharply. If suppressed national wages and increased national inequality is enough for you to reject trade, then it’s not clear why you’d accept an immigration policy that has the same effect.
"The central barrier to increased political integration between
Canadaand the United Statesis that there is almost no policy overlap between nationalist groups in the two countries, and thus fewer projects that can motivate these groups to set aside national partiality in order to participate in a joint undertaking."
