Since 1937, an annual celebration known as "Hands Across the Border" has been held at the Park, sponsored by the International Peace Arch Association. Hundreds of Scouts from the U.S. and Canada are in attendance and the highways and Ports of Entry on both sides of the border are closed for several hours for the event. There is a procession of Troops and world flags through the Peace Arch, signifying Scout unity around the world. Speeches are made by honored Scouts from Washington and British Columbia, and State, Provincial and local dignitaries attend. On February 28, 2013, after 90 years, the event's former organizers announced that "Hands Across the Border" had been cancelled. However, following public support the annual program was re-established in 2015.
