Continuous journey regulation

The continuous journey regulation was a restriction placed by the Canadian government that (ostensibly) prevented those who, "in the opinion of the Minister of the Interior", did not "come from the country of their birth or citizenship by a continuous journey and or through tickets purchased before leaving the country of their birth or nationality" from being accepted as immigrants to Canada. However, in effect, the regulation affected only the immigration of persons from India.
