Canadian ideals, 1957

This is how the Minister of Citizenship and Immigration greeted a new Canadian citizen in 1957:
Dear Madam,
I wish to take this opportunity of congratulating you personally upon the attainment of Canadian Citizenship. By this certificate of citizenship you have been granted the rights and privileges of the citizen of Canada. These rights and privileges entitle you to freedom of speech, religion, thought and action, the right to vote as you choose, and the right to be secure in your possessions.
Your citizenship carries with it the obligation of defending your adopted country in time of need, of living in peaceful brotherhood with your fellow Canadians, and of doing your part in the preservation of Canadian ideals and institutions.
I extend to you a warm welcome on this solemn occasion and I invite you to share with us the ancient liberties of a free people living together in harmony, under a democratic government which recognizes the rights of all its citizens.
Ellen L. Fairclough,
Minister
