The Nanabush story is a valuable record for understanding the lifestyle and thought system of Native Americans. In addition, this mythical figure contributes to the aesthetic value of literary works through creative writers in addition to the historical and cultural anthropological value of understanding the lives and lifestyles of indigenous people. In addition, the story of Nanabush secures the identity and uniqueness of Canada and becomes an important source of independence for Canadian literature. This study explores the establishment of Nanabush as a cultural symbol in Canada through a study of the character Nanabush in the mythology of Northern European indigenous people, and examines The Rez Sisters (1988), a representative play in which Nanabush appears, focusing on the meaning of Nanabush in the imagination of Canadian writer. In the play, Nanabush appears as a trickster, and it is difficult to find the aspect of a creator or cultural hero shown in the mythological texts. Instead, in this literary imagination, he is portrayed as a being who connects the past and the present and, as a result, meditates the spiritual bonds and collective emotions of Canada's indigenous people. He becomes an important means of realizing aesthetic values as much as ethical and historical values.
