Since then there have been major international reunions at other sites. At the Casselman Reunion in 1984, the second Sunday of July was proclaimed Casselman Day in 1984. Each year on Casselman Day, the Casselmans of Eastern Ontario hold a family church service and indoor picnic. There is a potluck lunch, a short business meeting, and either a guest speaker or some form of entertainment. Anyone is welcome to attend.
Preparations are now under way.
