Abstract: The lack of national spirit is one of the resistances encountered by Canada while building a nation. Based on the colonial union movement， Thomas McGee， an Irish poet， boiled down his nationalism to New Nationality from the perspectives of political system， economic development， ethnic relationship and native literature. As for politics， it proposes establishing Canadian confederation following the British system; as for economy， it stands for implementing trade protectionism based on national identity; as for ethnic relationship， it hopes to respect the interests of minority groups; as for literature， it urges to express Canadian native characteristics and advocate patriotism.

Key words: Thomas McGee, Canadian nationalism, New Nationality, confederation movement
