In order to obtain religious freedom the Jehovah’s Witnesses popularized the idea of a Canadian Bill of Rights and established numerous libertarian precedents before Canada’s highest courts (see Human rights).

On June 9, 1947, they presented a petition to Parliament for the enactment of a Bill of Rights with 625,510 signatures. John Diefenbaker became an advocate of the Canadian Bill of Rights and eventually introduced the Canadian Bill of Rights to Parliament during his tenure as Prime Minister.

The Canadian Bill of Rights was the precursor of the Canadian Charter of Rights and Freedomswhich is part of the Canadian constitution.
