Section 27 of the Canadian Charter of Rights and Freedoms states: ‘This Charter shall be interpreted in a manner consistent with the preservation and enhancement of the multicultural heritage of Canadians’, and we know surprisingly little about why the Canadian Federal Government agreed to insert it in the Charter and how this occurred. In this article I will use new historical evidence to explain both these things and I proceed in three stages. Firstly, I explain why the Canadian Federal Government agreed to include what became Section 27 in the Canadian Charter. Secondly, I explain how it was actually included. I then conclude the article by explaining why the evidence in it not only explains why and how Section 27 was included in the Charter; it also increases the possibility that a largely unsubstantiated claim made by certain prominent scholars is true. The claim is that the Canadian Federal Government's policy of multiculturalism was used to shape the Canadian national identity.
