The Ontario Lacrosse Association (Ontario Lacrosse) is a not-for-profit sport organization and a member association of the Canadian Lacrosse Association, the national governing body for lacrosse in Canada. The Ontario Lacrosse Association is the largest provincial lacrosse governing body within Canada. The mission of the OLA is to govern, improve, foster, and perpetuate the sport of lacrosse in Ontario. It was established in 1897. One of the oldest team sports in North America, the origins of lacrosse lie with the Native American people who lived in Ontario, Quebec and western New York. The first written rules were established in 1867, and although formal amateur provincial competition began in 1887, the Ontario Lacrosse Association was not established as the provincial governing body of the sport until ten years later. In the 1930s, the birth of box lacrosse (indoor lacrosse) increased the popularity of the sport among both athletes and observers. Although official competition was impacted by the number of participants available during both World War I and World War II, lacrosse teams have maintained activity on an annual basis since the inception of the Ontario Lacrosse Association.
