The LEO was founded by Bernard Cain in the mid eighties after a lot of lobbying with the OMHA to get it up and running.
The small Local League originally comprised of Lakefield, Ennismore, Otonabee, hence the name "LEO". Years later when the League grew to include multiple Centres in Eastern Ontario, the name was changed to the League of Eastern Ontario, while still allowing the short form of The LEO to be used. Today the League of Eastern Ontario, with the support of the OMHA, has largely grown to include 14 participating Centres.
Sadly Bernard passed away in OCT 2022, but the League proudly continues to keep his legacy of founding The LEO alive and growing.
