The setting in Chapter One is Toronto, Canada.
Life of Pi opens with a fictional author’s note, explaining the origins of the book. The author explains that while in India and floundering on the book he is trying to write, he travels to Pondicherry, where an elderly man, Mr. Adirubasamy, tells him he has a story for him that will make him believe in God. Adirubasamy tells the author about Pi, who the author manages to find in Canada, where Pi relates his story.
That story begins in Chapter 1. Pi describes his education at the University of Toronto, his double major in religion and zoology, and why he is so fascinated by the sloth, an incredibly indolent creature. He says that his great suffering has made all subsequent pains both more unbearable and more trifling. He loves Canada, although he misses India deeply.
