Why Canada did not join the American Revolution

Was there serious interest in Canada joining the American War of Independence to become a separate country?

No, in this account: differing colonial origins, imperial relationships, religion, and Indigenous alliances explain why British North America remained apart from the rebellion.

In this interpretation, different colonial origins and relationships with Britain help explain why British North America did not join the rebellion to the south. Economically organised settlements and French Quebec differed from colonies strongly shaped by Protestant groups dissatisfied with the Church of England. Those religious and cultural differences complicated the idea of a common revolutionary project. Indigenous support for Britain is linked to distrust of settlers from the Thirteen Colonies and experiences of earlier frontier conflicts. The complexity and variety of these relationships exceed a brief account.
