This essay examines the meaning of freedom of conscience and religion in s. 2 (a) of the Canadian Charter of Rights and Freedoms. Set within a polyvocal cultural heuristic, the essay uses the voices of dramatists, historians, judges, legal theorists and ordinary people to illustrate and document the development and evolution of the meaning of conscience. In particular, the essay focuses on whether freedom of conscience and religion is one integrated right or whether the notions of conscience and religion are separable, such that it is possible to argue a non-religious, secular claim to conscience on constitutional grounds.
