Thousands of people are coming to the area to open up their cottages and enjoy the beach this weekend, but some will also be stepping back in time.
They'll be re-visiting their high school days at the 50th Stayner Collegiate Institute Reunion starting on Friday.
Registration starts at 6:30 PM and after that former teachers and students can look through the decade rooms, have dinner at a number of local restaurants and then attend a social night and jam session.
On Saturday, there's a BBQ, car show, rugby and volleyball games and a sold out dinner in the evening.
But alum can still attend the dance at the Stayner Community Arena at 8:30 PM.
Seven hundred people are registered for the reunion.
Park Street Collegiate Institute in Orillia is also celebrating a half century of education this weekend.
