What begins as the completion of a North American road trip trilogy becomes something more personal. Theroux traces his own ancestral connection to Quebec, where his forebear Antoine Theroux arrived in the 17th century. Theroux meets his Quebcois friends and relations, then travels more widely through remote villages, multicultural cities, and sweeping landscapes that have defined modern Canada. Along the way, he speaks with farmers, refugees, writers like John Irving and Michael Ondaatje, and Indigenous leaders such as Tanya Talaga, listening as Canadians reckon with identity, belonging, and patriotism, often in response to the jabs and provocations of their southern neighbor.
