The Big Rideau Lake Association (BRLA) is committed to long-term environment protection and service to all who use our lake and share its resources.

Located on the Big and Lower Rideau Lakes in Eastern Ontario, the BRLA is a non-profit organization with roots back to 1911. The Association supports programs in the areas of environment, recreation, government affairs and lake safety. The BRLA is managed by a volunteer Board of Directors, assisted by seasonal staff.

BRLA Members are all those who enjoy the Rideau Lakes: cottagers, boaters and local residents. We each have a stake in protecting our lake community.
