Early life and education
Yerxa was born in 1947 on the Little Eagle Reserve, Couchiching First Nation, in northwestern Ontario. He studied graphic arts at Algonquin College(Ottawa), and fine arts at the University of Waterloo(ON).
Yerxa began publishing poetry and participating in group art shows in the 1970s, and had his first one-man gallery show at the Thunder Bay National Exhibition Centre and Centre for Indian Art, entitled "Renegade: The Art of Leo Yerxa", 1984.
Yerxa's designs were used for the Series Four 1975 (1976) Summer Olympic Coins. The coins bearing his designs included $5: Marathon Runner; $5: Women's Javelin; $10: Women's Shot Put; and $10: Men's Hurdles. His use of Algonquin art motifs in the design of these coins is considered an early example of Canadian public art expressions of indigenous values and aesthetics.
Yerxa is the author or several books for children, including the critically acclaimed Ancient Thunder. for which he received a Governor General's Literary Award in 2006. and Last Leaf, First Snowflake to Fall,
